i've heard a lot of people upset about the weld quality on some DC sports stuff, just food for thought.

and as already mentioned, don't expect anything major from bolt ons. with a header, high flow cat, and decent cat back exhaust you'll prolly only get 10hp from all of it.

I just heard problems with their ceramic/ mild steel header, havent heard any problems with SS and hey Ill take an extra 10 ponies any day of the week :D

I'll take any extra hp right now. I'm just slowly buying everything and then installing them all at once!

btw my factory cat is deteriorating. Now 2 things. 1. what would cause the original cat to go bad??

2. should I get a high flow cat if i'm in the market for both headers and catback exhaust system?? or should I just get an oem cat and then get the headers and catback exhaust????

My cat is going bad as well, starts to stink when I push the car hard or floor it sometimes. That's why I wanna get a new header and go full 2.5'' exhaust next summer, cat included. Should also help free up some more hp once my setup is finished.

well, think about this.

header + exhaust are meant to optimize exhaust flow.

what good is a header with a free-flowing collector if all those exhaust fumes just get bottlenecked at the cat?

to me it just makes sense to replace your cat when you're trying to get the most performance out of your exhaust system

That's not a cat, its a test pipe, you do not want that. If you're looking for a high flow cat get a random tech, catco, or magnaflow.

^ you corrected him on using "headers" and then used the same word in your own post:p


You won't see any big difference from cat-back exhaust, header and high flow cat combined. I didn't see much of any REAL difference.

At this point, engine swaps (H22) and forced induction (turbo or nitrous) are the only real ways to get bang-for-the-buck gains out of an I4 6th gen, IMO. Don't expect any sort of big gain from simple bolt-ons because you will be dissapointed if you do.

been hanging around this thread too much lmao lololol
