Pick stainless or titanium, choose your tips and decide how you want the valves controlled.\u003c\/p\u003e\u003ch2\u003eAbout IPE\u003c\/h2\u003e\u003cp\u003eIPE, also written iPE, started in 1998 as Innotech Performance Exhaust and now supplies valved exhaust systems for sports and supercars. Builds use T304 stainless steel and Grade 1 titanium, with TIG welding for strong, clean joints. AutoTalent is a US dealer for the IPE line.\u003c\/p\u003e\u003ch2\u003eMaterial and build\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eT304 stainless steel, handcrafted and TIG welded by IPE.\u003c\/li\u003e\n\u003cli\u003eValvetronic muffler with actuated valves for a quiet mode and a louder open mode.\u003c\/li\u003e\n\u003cli\u003eThe cat-back comes in T304 stainless steel or Grade 1 titanium.\u003c\/li\u003e\n\u003cli\u003eStainless starts with Chrome Silver tips. Titanium starts with Polished Silver tips.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow the Valvetronic muffler works\u003c\/h2\u003e\u003cp\u003eWith the valves closed, exhaust gas takes a smaller path, which keeps the car quiet around town and on the highway. With the valves open, the gas has a freer route out, and the car gets louder with a more open tone. IPE's systems offer On, Off and Auto modes. In Off mode the valves open on their own at 4,000 RPM as a safeguard.\u003c\/p\u003e\u003ch2\u003eRemote control and the optional OBD remote\u003c\/h2\u003e\u003cp\u003eEvery system with the remote option comes with IPE's Bluetooth remote control module. You pick the mode from the remote, and it needs IPE's accelerator signal line installed and set up for Auto mode.\u003c\/p\u003e\u003cp\u003eThe optional OBD remote adds IPE's OBDII hand gesture sensor. It connects through the car's OBDII port and talks to the car over CAN, so you switch modes with a hand gesture. It works only if the car supports CAN communication and has no other OBD devices in the port. It is an add-on to the remote, not a replacement for it.\u003c\/p\u003e\u003ch2\u003eChoose your options\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExhaust System and Tip Finish:\u003c\/strong\u003e Pick stainless or titanium together with the tip finish. Titanium adds $1,100 to the base price, and the upcharge for each tip is shown in the choice.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional OBD Remote:\u003c\/strong\u003e These cars can keep the factory valve control. IPE's remote adds $280 and the OBDII gesture sensor adds $570.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGood to know before you buy\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIPE says these cars work with the IPE remote and OBD control, or with the factory valve control.\u003c\/li\u003e\n\u003cli\u003eIPE says its headers with cats and muffler can be sold separately. Headers are not on this page.\u003c\/li\u003e\n\u003cli\u003eIPE uses the same cat-back part numbers on its 997 and 991 GT3 listings. Confirm the fit with us before ordering.\u003c\/li\u003e\n\u003cli\u003eDo not wash the tips with strong acid or harsh solvents. Light discoloration after heavy heat cycles is normal.\u003c\/li\u003e\n\u003cli\u003eIPE gives a one-year limited warranty from the ship date. It does not cover wear items such as gaskets, springs and heat wrap, or damage from poor installation. Tips are decorative, so IPE does not accept appearance returns once they are installed.\u003c\/li\u003e\n\u003cli\u003eFitment follows IPE's price-list application.
