STM 2G AWD DSM Stainless Turbo-Back Exhaust

STM Tuned Inc.



We price match!

The STM full 3" stainless steel turbo-back exhaust (TBE) for 2G AWD DSM is made in-house at STM from 3" mandrel-bent tube and tig-welded flanges with an Ultra-Quiet resonator for the perfect mix of sound and performance. Fits AWD models only and fits both 2GA and 2GB bumpers.

Downpipe options are available to bolt to the stock o2 housing or to bolt to a stock-location aftermarket 2.5/3" o2 housing or just add one of the STM o2 housings for a perfect fit. A 2.5" Remflex gasket is used between the downpipe and o2 housing for the best seal when using a 2.5" o2 housing.

Includes a GESi GEN1 ultra high output EPA compliant catalytic converter which supports up to 850 HP. The full exhaust utilizes all factory hangers and weighs in at (33.50) pounds with hardware (not including the o2 housing). Pictured installed on Cory's 1999 GSX with the STM atmosphere dump o2 housing (which is no longer available as of September 2023).

Available without the o2 housing or with your choice of the STM recirculated housings with or without TiAL MVS. If you purchase the TiAL housing, you will also get all the wastegate fittings that are included with the MVS, they are just not pictured.

Decent exhaust

I'd say for 999.00 it should definitely have vband flanges. It should also come standard with a bung for a wideband, or atleast make it a option. Other than that the welds were on point and the fit was perfect I'd rate it 8/10.

2G Eclipse Exhaust

Beautiful pipe work on this exhaust, I haven’t finished the build to hear how it sounds yet but looking at it is more than enough to justify the purchase! Thanks STM!
