I wanted to write this review so that others who purchase this down pipe can know about the pros and cons. To start off with, this was a very affordable down pipe. Other down pipes, including shipping start at like $500. But of course with a low price, quality is sacrificed. Haven't gotten to give it a good heat test yet with the turbo but welds seem solid. The 5 bolt flange plate did not line up to all of the holes on my turbos flange. I had to drill the holes on the gasket and on the down pipe flange to make 4 of the 5 bolts fit. (i destroyed the threads accidentally in one of the holes on the turbo). I don't really know if it's the down pipes fault for fitment or the turbo but figure it should get put out there. Fitting into the far was easy however this will NOT bolt up to your pre-existing catalytic convertor. The down pipe is 3" and the cat is 2". It's also a different length than the OEM down pipe so my entire exhaust had to be removed. The tubes/flanges for the external wastegate did not fit my wastegate entirely. The wastegate would want to be pulled up and away from one side while the other needed to be pulled down and towards to. Anyways, cheap solution was slap 2 gaskets on 1 side and fill gap with JB weld(i am a cheapo). Personally I would have welded completely around the tubes and flanges for the external wastegate. Mine were just tac-welded on. On the passenger side at the end of the down pipe the flange is at a sharp angle so one of the provided bolts needs to be used with the head of the bolt being on the down pipe side and thread goes towards the back of the car. The car did sound nice on start up but again not much testing has happened because my return line was bellowing smoke. Full honesty I would say I love my down pipe and it definitely saved me a couple hundred dollars. For anyone worried if this is a scam, it is not. I was a bit worried at first because of no reviews online but I waited the 2-3 weeks to get it shipped all the way to Hawaii and everything worked out with minor modification. If you are going budget then I would suggest this down pipe however if you want perfect fitment and top notch quality then go spend the $500-1000 elsewhere.
