Whats up guys,

I finally had my headers put in. And i had it dynoed yesterday. I actually 5 hp. I mightnow seem much but i would much rather have that 5 hp back to the wheels. I will return my headers and keep my normal svt headers in.

Were there any other changes that you have done? BTW what headers did you use?

Speaking from experience in the GM world I added headers onto my old Impala before i went completely nuts on it. It only increased by 6hp.

I have been looking at getting bassani midlength headers.

i used the mac headers , and i already got mac off road h pipe, and mac intake. I thought maybe it would help but for some reason it lowered the horse power. I thought about gettting the bassani headers also but they ran 700 bucks. I am still paying off the car so i dont have that kind of dough.
