yeah I got a 97 civic dx..and i changed all my piping from the exhaust manifold to 2 1/4 and i punched out my cat..but like all that runs into my stock muffler cause im still savin up for the axle back exhaust..and i was wonderin how much of a difference would i get when i put on a performance exhaust???any comments are accepted thanks...aite im out....peace

 

what mods do you have so far?? you should notice a diff. depending on the extent of your mods, not too big of one though. hope that this helps. good luck

 

Really you should feel a little power increase. Mostly on normal take-offs, feels like you shouldn't have to rev it as high to make the car move forward. Also you may feel a little less "lag" going from 1st to 2nd and maybe third.

Basically a slight change in throttle response. But hey its a start.

Good Luck
