I am helping my brother source some parts for his 04 Comp G. We are looking for some headers, doesn't seem to be a ton of options for the 04+ cars. So headers for the 97-03 GTP's fit on the 04 cars?
I have seen some recommend SSAC, I check out there site and again they are listed for the 97-03 GTP. I have also done of searching for headers on ebay and came across these.
OBX headers for 97-03 GTP
OBX Exhaust Headers 97-03 Pontiac Grand Prix GTP 3.8L : eBay Motors (item 370337853882 end time Mar-20-10 22:23:39 PDT)
They seem like a quality piece for the price.
So are the 97-03 headers an option for us? What about emissions looks like these eliminate the cat we don't have testing but without the cat will the car sound like ****?
