It would gain some hp, but it will be loud and will not sound good.

first off 120 is way too much to chop off some pipe. if you want loud get an exhaust cut out.

the factory mufflers are really restrictive.. since your on a budget, i would cut that **** off (yourself) keep those 120 bucks and invest in a catback for later.

i bought my car with this done to it... didnt sound HORRIBLE, but didnt sound good either. needless to say, it was the first thing i changed since i like to hear myself think... for 120 bucks you can buy yourself a decent replacement muff, magnaflow, etc and put it on yourself. you'll be MUCH happier

NAY!!!!!!!! Its going to sound like ****. At very most if you just want it loud get a bullet or a spiral flow muffler and put it in the mufflers place.

i had mine straight piped running through cats and it wasn't bad....i thought it would be crazy loud and obnoxious, but it wasn't....it didn't have that tone like you hear from alot of performance exhausts, but it was still better than bone stock IMO

I would say keep your $120, cut it off yourself, buy a single Classic Chambered Powerstick, and clamp the powerstick on with a band clamp, maybe with a turndown. That shouldn't be anywhere near $120 and won't sound like a dump truck.

I'd say to hell with just replacing/cutting off the muffler and pick up a used cat-back system for that price, then install it yourself.

Yes please try to keep these cars from getting any worse rep and put some sort of replacement muffler on there. Just cutting of the muffler is very ghetto / trashy.

OP. You could probably get a Magnaflow muffler put in place for that much. Or a cutout put in the I pipe. I had a cutout when mine was stock and I gained 10whp and 1tq on the dyno vs stock. So either way you can't lose.

definatly thanks for the advice. i would love to do it myself but not sure how to do it.especially if it involves welding. if i was to put a different muffler i would def. put magnaflow. but the cheapest ive found a magnaflow muffler for was 300 plus installation. so next question,thanks to the advice b4 im no longer gonna cut the muffler, but how can i buy the magnaflow and do it myself?
