I recently purchased some long tube turbo headers. I have 2000 GT with a 5.1 stroker engine. I sold my supercharger and now it is time for the turbos. I have a UPR k-member on it now and i was trying to find out if any one knew what k-member should be on it. I tried to install the right header and it hits on the k-member. I have tried to get on there web site and you can see the products but no contacts or anything on there. Thanks for your help.
