Our exhaust components are of the best quality and are proven power makers. All exhaust components are 304SS, with the notable exception of our Signature Titanum Catback, and lightwieght CEL boss. At a Mere 11.25lbs for the entire catback section, this is among the lightest of all catbacks.
Our turbo-back exhaust systems are another way to increase power efficiently. Made of 3 inch diameter polished stainless steel. We offer both 3-piece single tip and dual tips for a more subtle sound and look and two-piece N1 racing-style exhaust for the driver that wants to make a statement. Decreased back-pressure enables the engine to make more boost more efficiently.

In addition to our stainless steel units, GPMoto offers a one-piece titanium cat-back that not only flows as well as our stainless units but also weighs significantly less. Shaving weight improves handling as well as increases the impact of added power.

Equal Length Header:
PN 11001

Our headers are equal length
and feature an integrated up-
pipe. Equal back- pressure on
all cylinders equalizes cylinder temps and EGTs for better tuning and longer engine life.

Equal Length Rotated Mount Header:
PN 11002

This header is designed for our rotated mount turbo setup. By relocating the turbo we have made a more direct air path for the turbo and the intercooler piping. This header features a T3 flange for larger Garrett turbos.

Turbo Back Exhaust:
Our turbo back exhausts feature two O2 boss’s on the down pipe and one in stock location. Our exhausts are all 3 inches in diameter with two resonator chambers for a deep mellow tone and are available in three tip designs. Includes belmouth downpipe with wideband 02 sensor port, full catback with muffler style of your choice, and a stainless steel CEL boss.

Single Tip Turbo Back:
PN 11111
Twin Tip Turbo Back:
PN 11121
For a stock look with a slightly more aggressive tone this exhaust is great for the driver looking to stay stealth. This is a great exhaust for the Forester XT.
Another design with the sleeper in mind. Slighty louder than the single tip it is a great replacement for the WRX twin tip.

  N1 Turbo Back Stainless:
PN 11001
For the driver who wants maximum flow, this exhaust has all the flow needs of the weekend racer or serious street driver. This exhaust comes with a silencer to keep things on the down low when more attention is not what you need. This is the best sounding N1 on the market with a nice deep rumble.

N1 Turbo Back Titanium:
PN 11103

The same design as our stainless unit, but in lightweight titanium. This exhaust is a one-piece design for the driver looking to find the limit. More flow and much less weight equals a faster car, what more could you want?

CEL Boss:
PN 11151

Fix annoying check engine lights with this mechanical fix. This boss removes the o2 from the flow of exhaust so that the sensor runs cooler with an aftermarket exhaust. Aluminum construction for lightwieght. Near universal fit for most modern cars.
