Thanks for the input, when I'm ruler of this earth your death with be quick and painless.

if i was going as far as to replace pipe i would definitely do mandrel. Crush bent causes turbulence, which is bad for exhaust.

how bad though? like a 1-2 hp loss?

well i for a bolt on type car its probably nothing you would notice. Anything where you really start pushing more air is where it would start to show itself.

about to buy some pacesetters for the car in a day or so, I have an intake too. Think I'll be fine? I have my doubts I'll be doing anything major for a long time.

is there a size difference between the pacesetter y pipe and the stock one?

you should be fine with it. The y should be same, as its meant to bolt up to stock exhaust.

if i were you id leave the stock pipe its stainless and will last way longer, are you getting a new muffler too or do you already have one

Its not a bad catback at all. I know alot of people that love the sound of the dynomax.

hell if i had all the stuff for my turbo kit i would sell you my magnaflow cat back for that. good price though. ive know people that had dynomax before and they dont sound too bad. they just seemed to be kind of quiet for my liking
