Yeah, you tube is good for sound clips, that's for sure.

Has anybody had any "noticable" gains of torque?...I would think you would have to change the whole system.

 

no gains on the slip on, well maybe a pony in the higher rpm..
i have a fmf powercore s ti, and it has a nice sound, at idle it's close to stock, the higher you go, the meaner the sound is. plus they have quiet inserts into the muffler, it should move the sound level to almost stock level. .. love it.

 

Thanks for the heads up. I was thinking i wouldn't get much power, but thought there may be a slip on could offer "something."
