Its a 3.5' Mark H unit. The chassis shop routed the wastegate back into the downpipe. The overall look and quality of the downpipe is very good. The fit on this application, not so much. The downpipe was literally resting and melting the inner fender ( had to cut the inner fender) and needed a little heat and manipulation to properly clear the heater box and also the frame.
With all that done its a thing of beauty. We also added a V-band under the car so pulling this downpipe out can be done in 5 min
Nice engine bay. I used one of TR Customs 3.5s as well and ran into the same issue with the inner fender. Had to trim a good deal to clear but overall the quality of the pipe itself is very good. I modified mine routing the gate back into the dp downstream.
