Just OK!
Chris (New Jersey) | December 20th, 2025
Beautiful welds and excellent build quality. That said, the fitment of the right-side pipe was subpar. We were able to make it work with some modifications, but for the price, the fitment should be spot-on. As a repair shop with proper tools and fabrication capabilities, we could resolve the issue; however, a typical DIYer would most definitely struggle to install this without significant difficulty.

Terrible do not buy them

Doesn't fit well, hard to get it to seal. Gaskets do not come complete, missing EGR. Spoke with Will at PPE. No help, Joe the owner will not take a call or return my message.
