Just weld in a set of electric cutouts... Best of both worlds and way cheaper.

Headers are the way to go. They'll make the car a lot louder and you'll get a nice gain in HP to back it up!

Best regards,

My neighbors tell me all the time they hear me start my car in the mornings...haha..but I am thinking about doing this as well.

So, some LT headers with HF cats and a CAI will give me maybe another 50HP?

This will void the warranty right?

One more question, Pfadt is out of business and it looks like everyone liked them the most so what other brands come highly recommended? Kooks?

Headers will require tuning which can void the power-train warranty in the event of a major engine failure. With a good tune, you won't have much to worry about though.

I'd recommend Kooks, but Stainless works and ARH are also very good.

Feel free to call, PM or email me anytime with questions.

Best regards,

Tyler

I have read on here that some don't get a tune with headers. Will the car run like crap if I dont or have a check engine light?

Quad tips & sounds better than the trash cans you get w/o npp. Add to that what everybody is saying about adding to it via headers, cats, no cats, then it makes them worth it.
Did I mention that it looks so much better than the cans & it's lighter too.
