Hey guys i have a 08 GT and i wanted to get some headers and pipes to make it sound like a true muscle car!! I love hearing cars with that deep rumble noise. Anyways, does the brand of the headers really matter for performance? I know that they vary in price, but is the gain and sound the same for headers? how much horses can you expect from a complete exhaust done? This will definitely probably void my warranty, but i love the sound of exhaust.

If I could do it all over again I would go with bbk long tube headers to the shorty x-pipe w/high flow cats to 3 inch piping to slp loudmouth axlebacks. If you get headers make sure you get ceramic. Shortiies will be cheaper but you will potentaly see more gains from long tubes and bigger piping. If you do go with a combo like I stated above you might see low end loses until you add some real power like a Super charger. Go on You tube and find the combo that you like. Most Long tubes mean off road x or H pipe which mean emissions test failure, so keep that in mind. I hope I answered some of your questions.

bigger piping past the 2.5 inches we come with stock wont get you anything unless you are pushing lots of HP. its going to hurt n/a performance if anything becuase we dont have that big of engines. And you dont need ceramic coated headers either. Very few companies actually have their headers coated.

But it always helps reduce the heat in the engine bay getting ceramics. I meant to say that you dont get the real advatage from LT and bigger piping until you add lots of power, my bad. Its just something to keep in mind if you plan on S/cing someday.

Im in the same boat right now but have narrowed it down. I was originally looking at bbk's but I want a catted X and for the money I would rather drop a few hundred more and go with the kooks or American Racing. In what I have seen between the S197 and pervious models BBK's just dont seem to be enginered as well as the little more expensive ones. Just my 2 cents from what I've seen. But I agree what was mentioned before go to some races or car shows and talk to the guys with a similar car and see if they will fire it up for you and let you listen to it in person. You tube will give you a rough idea depends on quality of camera there using but nothing beats hearing it in person. I heard a car with the FRPP shorties catted x and magnapack and was amazed at the sound that came out of that thing, especially when he did his burnout and launch down the track.

I'm running BBK long tubes with their x-pipes w/cats, no problems here, would recommend it to anyone

Eagle I keep telling people about your exhaust whenever people ask about what they should do. I like your set up so much I might do a complete change.

Seriously? I know you said you wanted 3" piping i've only got 2 3/4 with the magnaflow mufflers, but im really really pleased the sound, it's just amazing. The guys that dyno tuned my car specialize in 4.6's, and when I picked it up he looked at me and said "that's how its supposed to sound right there" it was pretty gratifying lol. I'll recommend anything on my car though it's all run amazingly

And hey, for what its worth people, if your gunna pay the money for a pair of kooks, i'd get a guy to build ya some.
