Do you want an additional 15 horsepower, an extra 10 ft. lbs of torgue, all from a chambered exhaust system installation, well I saw it today from a dyno on an LS1 Firebird. Engine was making 333 prior to the GMMG System, 355 with. Made a believer out of me, thats why I went with the system on my 2000SS. (THIS IS NOT THE BRAXXTON)

To anybody that might be confused.

The system is the third version of the Braxxton Chambered exhaust it's just GMMG,Inc. dropped the Braxxton name on it, so the system is just called Chambered Exhaust!

Hey MOO4340,
That's awesome about the dyno results!

Did the Firebird make 333rwhp or was it caculated from the flywheel. The numbers are a little high unless the car had a lot of mods before it got the exhaust. Also 01SunsetOrangeSS has a point about the hp numbers. Usually bone stock a LS1 dynos at 300-310rwhp that amounts to 350hp at the flywheel, so MOO4340 could you give us some more details. I'm sure the exhaust has a hp and torque gain, but 22hp sounds like too much!
