im saying its the PO because i have only had my car for less than a week, and in that week....its finals study week for my college, so the farthest I have driven in my car is to the gas station (2 miles away) and to my mechanics garage (3 miles away). if I dented the exhaust I have no reason to lie about it and say its the previous owner..but I did not dent it...so yea thanks for the helpful post.....and if you were being facetious, my bad, its kinda hard to tell on a forum the context of someones statement...cheers brah

Well, that dent does disturb airflow. No doubt about it.
Will fixing that dent make your car faster? You wouldn't feel it.
Even the dyno won't show gain, if any. (after all, how much HP does aftermarket cat-back give you, other than good sound?)

The pipe isn't crushed that bad.
If you were going to change the exhaust anyway, why bother fixing it?
I'd wait and get the whole thing changed later.

thanks man, I figured the loss if any would be negligible...I am just going to hold out until I can order a new exhaust...however, pretty much every exhaust I have seen in my search is a cat-back design...and the the other ones are a track pipe style no cat design (with the option for O2 sensor CEL fix) I could be misinformed but putting that kind of exhaust on a stock Naturally Aspirated car is actually detrimental to performance, isn't it?

If it were my car, I'd hack that pipe in half right after those dents, use an exhaust pipe expander and some light taps with a hammer, perhaps a torch as well, to get the pipe round again, mount it all up to the car and tack weld it in place with everything fully bolted up/tight. Then remove the midpipe or let it drop down a bit and weld up the cut.

Shouldn't take more than an hour and a half.

how much do you think an exhaust shop would charge to do that....that job is way beyond my scope in terms of tools and mechanical experience
