Ok i have been planning to replace from the exhaust manifold back to the end of the car on my 01' integra GSR. I have searched so i dont get flamed. I want to use a cheaper header because i havent decided on turbocharging yet. so i wanted to keep the price down. I know the GSR of the 94-99 and GSR of the 00-01 is different cause of the length. Are the cat backs the same? and where can i find a 2.5" cat to use with a 2.5" header to fit the OBDII 01 gsr. Final question will this header fit with the exhaust?http://cgi.ebay.com/ebaymotors...33631 thanks!

just wait man not worth spending the money. OR actually, buy it and when you decide to go turbo sell me your header for 50 bucks. lol jk. I am making 185WHP with a lsvtec with a stock exhuast manifold. Wait my son unless money grows on trees for you.
