So someone on here posted a link to summit racing, where dynomax will give you a 75$ rebate on certain catback qualifying exhaust systems. so i can basically get aftermarket exhaust for 25ish dollars depending on what i get. my questions are, one is it worth it? both performance wise and sound wise, and two, do i have to do any welding for install?
Any opinions, suggestions, and whatever!

 

ah crap, just realized its in the wrong section probably, if a mod sees this and thinks it needs to be moved go ahead lol

 

no body?

 

Yea it's worth it and no you don't have to weld
