This is the best you can get for your non-turbo exhaust system!!! This kit is a FULL 3SX engine-back fully-stainless steel exhaust! Start with our custom 3SX Long Tube Headers, leading into a high flow catalytic converter, and then into our quad-tip cat-back exhaust system.

Don't believe the hype?
The proof is in the numbers! We subjected our 96 3000GT to a battery of exhaust installation and dyno testing and have shared all the results in an FAQ article: 3SX NA Exhaust Dyno Testing. Here is the dyno graph comparing the "all stock" to "all 3SX" exhausts and showing the 20 hp gains at 6500 rpm.

 

This is the dyno video of the car with the full 3SX exhaust installed. Check out the 3SX NA Exhaust Dyno Testing for many more videos.

 

On-Track In-Car Road Course Video
This is Eric's FWD NA Stealth running on the Corvette Museum 3.2-mile Road Course. He is running the 3SX Long Tube Headers, 3SX Race Pipe, and 3SX Catback.

Note:  The long tube headers were designed around the manual trans.  If you are going to install this on an automatic you might need to dent the pipe to clear the inner halfshaft.
