I just installed a 3" THDP and I need to know if there is a standard length test pipe with dump that is of correct lenght for these cars. I got a poliched stainless steel 3" testpipe with dump from Ebay, and its like 5" to short. Is there a short version and a long version of these pipes? or is it just random, and the user has to make it fit?
