I dont agree, I think headers are an excellent investement. When done along with the rest of the exaust its been dynoed to add 10-15 HP. While not an astonding number, remeber that every time you add another mod, the headers give you a little more as well.

Besides they sound nice

 

oh man look what i started lol didnt mean to reply to u 2000gt just meant i was the guy that started posting exhaust questions in 4.6 im a nooobie s*it happens lol

 

Headers are an excellent investment along with a larger than stock X or H pipe. I had all mine done and the power difference is awsome!!! Mac ceramic coated headers is what I have and they still look brand new!

 

Yeah, all you non-emissions guys have it made. F---ing California and our smog laws. [:@] Long tubes are out of the question for me. I'm actually thinking about registering my car to my uncle's address though since he lives in a non-smog area...

 

what are the best headers to go with if u need to pass emissions here in cali.... shorties or mid length?

 

i'm new to this site. but anyway is anyone haveing problems with there mac cat backs hitting the axles on the the driver side?

 

I have the Bassani SS axel backs on my 06 GT. I'm thinking about the mac longtubes and a O/R prochamber. Has anybody found any sound clips with this set up????

Thanks guys
