On Up-pipes Sinister Diesel has opted to get rid of the bellows in favor of a much stronger, longer lasting "double slip" flex joint. In turn, there are now, no bellows to heat fatigue and crack. It will still allow the upper, and lower sections of the Y-Pipes to flex and move due to heat expansion, while maintaining a 100% seal. The double slip also allows some flexibility to account for different tolerances in the motors from year to year, as well as aftermarket turbo kits. All of their up-pipe kits a fully TIG welded on a fixture, as well as back-purged for the highest quality, strongest weld possible. Sinister Diesel Y-Pipes are Built with Solid Stainless Steel CNC Flanges and Stainless Steel Tubing. These Y-Pipes are Fully Tig Welded.

What do you get when a group of diesel, truck and 4x4 off-road enthusiasts get together with a dream of changing the automotive aftermarket industry? You get Sinister Diesel. Founders Brian George, Michael Mitchell and their whole team share a love of everything diesel. One afternoon, while working on Brian’s truck they thought of starting a new company. Sinister Diesel® actually started out as MKM Customs. So, why the switch to the Sinister name? It appeals to Brian and Mike because they feel it captures the spirit of the diesel lifestyle. “The spirit of diesel truckers is like our own,” Brian says. “A little bit rebel. Of course, we don’t all live a rebel lifestyle, but we all share that spirit. The name Sinister captures that sprit perfectly.”
