How To Install A 2005-2010 Performance Exhaust For Your Ford Mustang

Once the hangers are disconnected, the mufflers drop right out of their pockets. It is amazing how easy this is when you consider muffler replacement on '65-'04 Mustangs.

As mentioned previously, it's easy to get the muffler hangers mixed up and wind up with mufflers that won't hang correctly. Take digital pictures when mufflers are removed so you can keep the hangers in their original locations when transferring them to the new mufflers.

Marlon Mitchell disconnects both the exhaust pipes between the H-pipe and mufflers. This is as easy as muffler removal.

The new Dynomax 3-inch pipes are installed next. All Marlon has to do is plug them into the existing H-pipe and tighten the clamps.

Installed, our 3-inch pipes look huge. Clamps have been tightened and we're ready for mufflers.

Dynomax bullet mufflers get new clamps thanks to the hefty 3-inch sewer pipes. These clamps work the same way as the factory pieces to provide solid security without the hassle of a saw and welder.

Hangers are installed on our Dynomax bullet mufflers just like they were located on the factory mufflers, which is why we suggest paying close attention to the original locations.

The Dynomax mufflers are installed as shown, then clamped to the pipes. Carefully check muffler positioning, getting the tips uniform on each side. Where it gets challenging is muffler positioning. When hangers are welded at the factory, they move as they cool, which alters hanger position during contraction.

Sometimes, you have to heat and bend the Dynomax hangers to get muffler positioning just right. This is typical of most aftermarket mufflers for late-model Mustangs.
