Its a shame because this downpipe is the highest quality i've seen. Welds, flanges, everything is top notch. It has an awesome heatcoat on it, just doesnt work iwth my gtx3071 turbo . Swapped it from my CNT Catted Downpipe and instantly ran into problems. Only 2-3 lbs of boost and noise coming from turbo. The IWG is hitting the divorced lip in the pipe since atp uses an extra wide wastegate door. Just wanted to throw that out there to others that might not know.

Anybody need an awesome downpipe without a ATP Turbo? ha

 

Go ewg.

 

hmm good to know.

 

Im working with Grimmspeed to get the problem resolved now with ATP Turbos. Hopefully we can get this tweaked and sorted out. Its to nice of a dp to pass up.

 

Ok ive been gone for vacation and just got back recently.

The easiest way I found to make this work is to bend the divorce lip 1/3 of an inch to give the wastegate that little bit of extra clearance. Works perfect now. Didnt need any cutting just a little bending with some vise grips and now it fits like a glove. Im sending Grimmspeed over the info so they can address the problem.
