Customer Reviews
★★★★★
Quality Downpipes!
Verified Buyer — Alek (@thatblackraptor) | January 31, 2024
Installed these on my 2018 F-150 Raptor. Install took roughly 3-4 hours with simple garage tools. The most difficult part being removing the studs from the turbos but Stainless Works provides the tool required! These downpipes have the turbo adapters built in and are stout! Such an upgrade from stock, you'll instantly feel the turbos spooling up quicker! Truck doesn't feel as restricted anymore and definitely is more free flowing!
