had them on mine... I'm now using the 30's. no difference in sound at all (but my motor isn't stock either), just got more torque from the added back pressure.

True, put a wet rag in your mouth and tell me if you run a marathon faster.
No engine made likes back pressure. Your gain in torque was possibly from increased exhaust velocity. This is why some engines will run better overall with a 2-1/5 inch pipe over a 3 inch pipe. There is more exhaust velocity a lower rpm/smaller engine will get more flow from a small pipe over a 3" pipe!
Apply this to cyl heads as well on the intake port runners

Your dyno pulls didn't improve because of 'back pressure', kiddo. If you actually believe that drivel, you have a lot of research to do.
