Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars.  Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly.  The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves. Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction). By replacing the factory downpipe/catalytic converter with our Sports Series 4" High Flow Metallic Catted Downpipe, more power is unleashed!  The factory catalyter uses a 900 cell ceramic core. What the 900 cells means is that per every inch, there are 900 "cells" that the exhaust gas must pass through. We use a 200 cell metallic core. By having less cells per square inch, these individual "cells" are bigger in size thus allowing exhaust gas to pass through it more easily. Thus, the lower the cell count, the higher the flow. Higher flow = more power, faster turbo spool up (less turbocharger lag) and better throttle response. Bottom line, faster. The benefits of a metallic catalytic converter vs a ceramic like the factory is that it can take higher temperatures and is more durable (last longer). They are also lighter than their ceramic counterparts.   200 Cell Metallic Catalytic Converter Element Our Sports Series 4" High Flow Catted Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping.  They are 100% TIG welded by our in house fabricators and built in the USA.  The factory turbocharger turbine housing utilizes a 4" V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel.  Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods.  The O2 sensor is positioned at the factory location.  Since the outlet of the turbocharger is 4" and the factory exhaust system is 3", the factory downpipes reduces size using short transitions from 4" before the catalytic convert and 3" afterwards.  Due to space needed for the cataylic converter, the factory downpipes reduce in size using very short transitions.  Since our catless downpipes delete the cataylic converter, we have more space.  Thus, we use very long transitions.  These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller.  This results in less exhaust turbulence and backpressure which again improves throttle response and increase turbocharger spool times (less turbocharger lag).  The factory downpipe utilizes a flex bellow section that allows the exhaust system to move.  This eliminates undue stress on the exhaust components like the exhaust system, downpipe, turbocharger and exhaust manifold.  Many of our competitors do not feel it is important to keep this.  While you do not see any adverse affects right away, over time, the stresses caused by not having a flex section and having a rigid exhaust system will cause premature wear and tear.  Any stress failures like cracks will form quicker than usual on exhaust manifolds and exhaust components.  Also, without a flex section, the exhaust system cannot properly deflect impact.  Especially on lowered cars, whenever the exhaust system contacts the ground, the entire system gets pushed up.  Without a flex, you can imagine how much stress is put into exhaust components like the exhaust manifold when the exhaust is pushed upwards.  We fully understand that durability of our products is important.  Thus, like BMW, we incorporate a flex section into our downpipe.  Our flex sections are 100% stainless steel (cheap flex sections only have stainless steel center braids and steel caps) to ensure corrosion resistance.   OPTIONS Ceramic Thermal Coating -  The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out.  This keeps underhood temperatures lower and less heat absortion by nearby parts/surfaces.  Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure.  The ceramic coating also adds additonal corrosion resistance.  We utilize the best ceramic coating possible.  Our thermal coating can resist up to 2000F of heat.  It is available in black only (all the other colors cannot withstand heat that high). Additional O2 Sensor Bung -   An additional O2 sensor bung can be added so that you can easily add a wideband o2 sensor and gauges so that you can monitor air/fuel ratios.  The additional O2 sensor bung will come pre-installed with a plug so that you do not need to run the o2 sensor right away. Optional EGT (Exhaust Gas Temperature) Bung -  An additional 1/8" NPT bung can be added so that you can easily add a EGT sensor and gauge.  The optional EGT sensor bung will come pre-installed with a plug so that you do not need to run the EGT sensor right away.

Optional Synapse Synchronic Blow Off Valve now available!!! Optional HKS Super Sequential Blow Off Valve now available!!! Limited Lifetime Warranty. Again, another parts development directly from our 135i Time Attack racing program.  The factory diverter valves were causing an issue of not being able to hold up against the rigors of high boost application, therefore they needed to be replaced.  Thus attention was brough to the factory diverter valve pipe and the need to optimize for maximum performance on a race car facilitated the need for a new pipe to be built.  Often ignored, charged intake airflow characteristics greatly affect throttle response, turbo lag and ultimately maximum power potential.  Smooth bends and minimal obstructions are ideal.  This is not the case with the factory diverter valve charge pipe.  On the factory diverter valve chargepipe features a sound baffle for the diverter valves.  This sound baffle is connected on the side of the factory diverter valve  charge pipe which splits airflow.  This causes turbulence inside the pipe which slows the charge intake air velocity (speed of the air traveling inside the pipe).  By removing this turbulence (by eliminating the factory diverter valve sound baffle), increased throttle response, decrease turbo lag and ultimately higher maximum power potential can be realized.  Our Diverter Valve  Charge Pipe eliminates this sound baffle and thus eliminating the unneccesary turbulence in the diverter valve pipe, keeping charge intake air velocity at it's maximum.  Apparrently, BMW thought the same thing as later model (2009-10) did not come with this baffle.    Since one of the reasons for changing out the factory diverter valves was to prevent boost leaks (from prematurely opening on high boost), causing boost leaks while upgrading the diverter valve would be counterproductive.  During our research and development, the connection at the throttle body was looked over very carefully.  The factory diverter valve is connected to the throttle body using an o-ring inside the throttle body flange which is locked in place by a c-clip, which works very well.  It also make removal/installation quick and easy.  Our testing had shown it could hold quite a bit of boost.  During our testing, we had pressure tested this connection up to 25 PSI.  The reason why we stopped at 25 PSI was because at 25 PSI, one of the intake pipes on the turbo blew off and we could not test any higher.  Hoewver, we were confident that it would easily hold over 25 PSI as the throttle body flange showed no signs of failing.  Also, keep in mind, this type of connection is used throughout the engine, in many crutial areas like the coolant radiator system as well as the clutch system.  If BMW did not believe in the durability of this type of connection, they would not use it in such important areas. Many of our competitors use a silicone hose connection for the throttle body connection.  It is not designed for a silicone hose connection which is used by all the other brand diverter valve pipe upgrades in the market.  The throttle body lip is too short and there are no "beads" to prevent the silicone hose from blowing off under boost.  Even though it is the easiest way to  "rig" together, it is not ideal.  The best way to connect the new diverter valve pipe to the throttle body is to replicate the same connection which we did.  We spent a lot of resources developing and manufacturing this factory style connection for this reason. The same issue came with the MAP sensor.  The MAP sensor seals to the factory diverter valve pipe via a o-ring on the sensor itself.  Having a hole in a silicone hose will definitely cause a boost leak as it will not properly seal.  Therefore, again we CNC machined our own replica MAP sensor flange that utilizes the same factory o-ring seal. Charge Pipe Finishes : The Diverter Valve Charge Pipe is available in the same 2 finish options as our intercoolers.  It is available in a mirror polish finish.  It is also available in our Type III Hard Black Anodizing for the guys that want the stealthy, factory look.  An added benefit of the Type III Hard Black Anodizing is that it hardens the aluminum piping and makes it more durable against accidental damage (like dropping the pipe). We also offer our Diverter Valve Charge Pipe in any anodizing color of the rainbow you want (special order) and is available in only Type II Anodizing (asthetics).  It is available as a special order item and is not stock.  Brush (or plain) finish is also available. 1/8" NPT Bungs (For Methanol or Nitrous Injectors) : With the popularity of methanol injection systems and nitrous systems, we have added the option of having a 1/8" NPT  threaded bung (for methanol or nos injectors) welded to our diverter valve charge pipe.  This allows quick and easy installation of methanol/nitrous injectors that are used in methanol injection systems and nitrous systems.  You have the option of adding 1 or 2 injector bungs.  Each 1/8" NPT bung will come with a plug so that you can run with or without the methanol injector.  This is perfect for those who do not have the Methanol Injection yet but plan to do so in the future. Blow Off Valves (BOV): The standard option for our Diverter Valve Upgrade Pipe is designed for either the factory diverter valves or aftermarket "factory style" diverter valve.  Also available is the TIAL Blow Off Valve option which utilizes the TIAL Q Blow Off Valve (BOV).  The TIAL Q BOV features a large 50mm (2") valve to quickly discharged built up boost pressure.  Since the TIAL Q BOV vents to the atmosphere which causes no restriction to venting boost, it reacts faster than recirculated diverter valves.  The internal valve spring can be changed out to different spring rates which allow adjustability.  This allows versatility as it allows you to increase the spring pressure in the future for when you run higher boost levels.  Therefore, it eliminates the need to purchase another BOV or diverter valve if you increase boost levels.  Essentially, this is the last blow off valve you will ever buy.  The TIAL Q BOV is available in 6 different colors: black, polished silver, red, blue and purple.  The black color option is standard.  If you want any other color, please specify when ordering. Due to popular demand, we are now offering our Diverter Valve Charge Pipes with the Synapse Synchronic Blow Off Valve flange welded to our Diverter Valve Charge Pipe.  You can order it with just the flange welded on or with the Synapse Synchronic BOV included.  The Synapse BOV option requires an aluminum flange that is not included in the Synapse BOV Kit (unlike the TIAL BOV which is included).  The Synapse aluminum BOV flange is $25 extra. HKS Super Sequential Blow Off Valve (SSQV) 4 Blow Off Valve (BOV).  You can order it with just  the HKS BOV flange welded on or with the SSQV BOV included.  We include only genuine HKS SSQV 4 (no oversea knock offs like you see on E-bay).  The HKS BOV is designed to make a loud sound when releasing.  Choose this option if you want all your neighbors to hear you coming down the street. HKS SSQV 4 Blow Off Valve HKS SQV Racing Blow Off Valve is a larger version of the HKS SSQV 4.  It features a 51mm valve to release more pressure.  You can order it with just the HKS Racing BOV flange welded on or with the SQV Racing BOV included.  We include only genuine HKS SQV Racing (no oversea knock offs like you see on E-bay).   HKS SQV Racing Blow Off Valve We can also build our Diverter Valve Charge Pipe to utilize any BOV or diverter valve you desire.  Love the way the Greddy BOV sounds?  No problem, we can weld any BOV flange on our Diverter Valve Charge Pipe so that you can utilize any BOV or diverter valve you want.  Due to the fact that there are so many options for BOV's and diverter valves, it will be impossible for us to stock these options.  Therefore, it is available only as a special order and will be built to order.  Contact any of our authorized dealers for more information on how to order this.  Only the TIAL, Synapse and HKS BOVs are kept in stock. Options: Add a replacement throttle body C-Clip.  If your factory throttle body c-clip is lost or broken, you will need to order this.   CAUTION:  This product is intended for  OFF ROAD USE ONLY .
