MAK Performance created a simple cat-delete system for the latest Mustang GT

From the moment we laid eyes on the 2015 Mustang GT’s exhaust components, we knew that driver-side catifold would be an issue. The fusion of exhaust manifold and catalytic converter would make it difficult for enthusiasts to just swap on a high-flow mid-pipe for the track. This setup would seem to mandate a move directly to headers. Well, that’s not quite the case…
The clever folks at MAK Performance in Hialeah, Florida, created Off-Road Cat Delete Pipes (PN MAK-MUS15001; $399) for the new 5.0 Mustang. Yes, this setup still requires some cutting and welding on the factory manifold, but it does offer a more affordable solution than moving right to a complete exhaust system upgrade.
“On the S550—more than previous models—the exhaust is a great point of restriction. Mustangs have not had 2.25-inch exhaust since the early ’90s, so with this new Coyote motor we knew that size piping was just begging to be upgraded,” say the folks at MAK. “While Ford made some changes that do not allow this to be as easy as in years past we have taken out the guesswork and provide detailed instructions with pictures to make the process as painless as possible.”
The kit in question includes 3-inch, mandrel-bent, 409 stainless steel piping. After you cut and weld the driver-side catifold, this setup retains the factory connections, and the kit includes all the necessary hardware and bracketry. MAK Performance describes it as a 75-percent bolt-in, so the other 25 percent is done by taking your factory driver-side manifold to an experienced welder to mod it for the new setup.
MAK is also offering resonator, a.k.a. suitcase, deletes in H- and X-pipe configurations that will bolt up to is own cat-delete pipes or the stock exhaust.
