well, now that i got serious about putting the exhaust on, i get the 02 housing bolted on and it sucked royally and will most likely leak(bottom back bolt). i went to put the downpipe on, and it doesnt fit. the closest i can get it is where i can still see into the 02 housing. nothing goes right for me. now, i gotta get on the phone with atr and see if they will take back this 6 month old downpipe that has been sitting in my house. :-(
