Hey yall,
I have an 04 G coupe with HKS knock off(Godspeed) cat back exhaust with Megan resonated test pipes and it sounds great.
My question is if i replace the headers will i get an even deeper growl and any performance increase?
Thanks!

 

If you add headers to that mix, it will rasp like crazy.

 

Performance wise you will not notice any difference. My exhaust tone became slightly higher pitched and a lot louder when I installed headers.

 

true that....same thing happen when i put on my long tube headers.......but with the motordyne tdx v2 it still sounds sick

 

^

Any vids?

 

headers don't do much(performance wise) for non-rev's w/o cams

 

here's a vid.....never got a tune yet jus dynoed after a Nismo 350z HR

261whp 250wtq. the Z had 276whp 253wtq. not bad in my opinion. he has all the boltons NA except headers and tuned

 

sounds sick

 

I will be installing adjustable cams pretty soon
thanks!!!!!

 

I have your exact exhaust setup except my HKS knock off is the Xo2 ive heard the the godspeed rep is really raspy but i added megan headers to my setup and i loved the way it came out not to raspy. As the others said you wont really feel a huge increase unless you get cams and most importantly a tune. But if you have someone who will do the install for you for cheap then hell go for it but if not i wouldnt do it.

 

jus a quick note.....I sold my friend my motordyne tdx v2 and he had the Xo2....the response is now quicker he picks up faster, I'll see if he can get a dyno sheet for his increase.
