STM Aluminum Cat-Back Exhaust - EVO 8/9

Product Description

The STM Aluminum Cat-Back Exhaust for Evo VIII-IX bolts to your factory cat or test pipe and is insanely lightweight at only 9 pounds!! The entire exhaust is fully aluminum, tig welded in house utilizing the STM Aluminum Flanges and Vibrant Aluminum Race Muffler. All gaskets and hardware are included as well.

The STM Aluminum Cat-Back features a unique 3-piece design which not only cuts down on shipping costs that most exhaust systems bear, but the back section is replaceable between USDM VIII and JDM IX bumpers. So if you purchase the cat-back for your VIII, and upgrade to the IX rear, you only have to buy the back section of the exhaust for a perfect fit to your new bumper (call to order.)

STM has been running aluminum exhaust systems for years on the streets and at the track. With daily driven cars and 1/4 mile passes in the high 8's at 165+, we have tried and tested the performance results.

- Weighs only 9 pounds!
- Tig Welded Aluminum
- Made in the USA
