and every body,i need everybodys opinion,wich exhaust system works better,gives more power,sounds the best,on the 1990tt i used to have back in p.r. i had hks exhaust system from front to back i liked how it use to sound,but its theres any other exhaust system out there that really gets the job done better,later will

 

as far as the sound goes anyway.

This site has sound and video clips of exhaust systems. It should give you a rough idea of how certain exhausts sound. Of course I wish they would have sound clips for the Stillen exhausts, so you could here how shitty(imo) they sound.
I'm pretty sure someone around here has access to an exhaust comparison that some magazine or similar has done. Post a link anyone?
Keep in mind that aftermarket high-flow cats, downpipes, manifolds, and test pipes will all affect sound and hp figures.

 

thanks rizz,hks i think sounds the best,and not that expensieve,later
