STM 1G AWD DSM Stainless Turbo-Back Exhaust

STM Tuned Inc.



We price match!

The STM full 3" stainless steel turbo-back exhaust (TBE) for 1G 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 1GA and 1GB bumpers and bolts to any stock-location aftermarket 2.5/3" o2 housing or add one of the STM o2 housings.

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 34.80 pounds with hardware (not including the o2 housing). Pictured installed on the STM 1992 Talon shop car.

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.

Additional Fitment Notes:

Beautiful craftsmanship!

This has to be the best 1G exhaust on the market. Next time it’s outside, I’ll get some audio and post!
