Description

The Active Autowerke Stubbies let E9X M3 owners who run the Signature X-pipe put their factory primary catalytic converters back in the system. They are a low-cost alternative to buying a separate set of high-flow cats, and they are sold as a set of two.

The factory cats are not included; you reuse the ones that came off your car.

What It Does

The front section of the Signature X-pipe comes off with its V-band clamps. A competent fabricator cuts down your factory primary cats and welds a stubby to each, turning them into a compact pair that drops in where the X-pipe front pipes were. From then on you can swap between the straight pipes for the track and the cats for the street as often as you like, since there are no gaskets to replace. The X-pipe keeps its performance either way, and the shorter factory cats are also easier to store.

Materials and Construction

Stainless steel stubby adapters with a mounting tab for each side. Installation requires cutting and welding the factory cats, which should be done by someone experienced.

Features

  • Sold as a pair
  • Reuses your factory primary cats
  • Swap street and track front pipes in minutes
  • No gaskets needed for repeated installs
  • Compact, modular package

Special Order Items

Some items may be special order specifically for the customer’s vehicle. These items generally require a deposit or paid in full.

** All cancellations that are requested that are NOT due to items not being in stock or delayed by the manufacturer are subject to a 5% processing fee. When you place an order with us we pay credit card fees that are NOT returned back to us. We will absorb these fees if we do not have the item in stock OR if you agree to the original ETA and that ETA is NOT met. If you decide to cancel for any other reason you will not receive this 5% fee back
