It's 99% bolt on.. The only thing you have to do is drill and tap your upper oil pan for the oil return line coming from the turbo. I leave the flange on the end of the downpipe off as well.. So you can configure it however you want with any after market or home made exhaust setup. Other than that.. it's bolt on..
If you want to discuss pricing.. please email me at [email protected] I try to keep business off of public forums as much as possible.. Since I don't pay for advertising here.. I don't want to offend the owners..
