ive stfa but cant seem to find any good tips/diy for an atp downpipe install...tia
Look for ANY dp install. I think I did a DIY on a downpipe even. Basically its four bolts at the turbo, and then a slip fitting about 4 feet down where it connects to your catback, and then remove two 02 sensors.
Then to the same in reverse to put the new one in.
You will have to take ott both of those cross braces under the car too, but theyre only 4 bolts each, so that shouldnt kill you either.
