Coupe

This full stainless-steel cat-back system begins after the front over-pipe with a 76mm (3”) front-pipe with tucked resonator to a full 3” mid-pipe all the way back to the rear section. The 3” piping then splits to two large 63.5mm (2.5”) inlets for the polished, 101.5mm (4”) DD-R mufflers via our precision Y-pipe. The DD-R is finished off with removable dual GPP engraved stainless steel slash-cut tips.

The system sounds amazing and looks great on the car. The only problem I’m having is the tip on one muffler was bent upon arrival. Corey is doing his best to come up with a solution with Greddy, hopefully sooner than later. All I’m asking for is a replacement tip in exchange for the bent one that the system came with. Low rating due to product not being up to quality control standards. I will change rating when issue is addressed and fixed.
