3.5" Single In/Out Race Muffler Style 1

These are drawn for a single 3.5" in and 3.5" out, so the file's already set up for that size. You just run the DXF on your plasma, laser, or waterjet and build it from there.

The files don't lock you into a thickness, so go with what's standard for your exhaust build. If you want a recommendation on material or a shop to cut and roll it, shoot us an email and we'll point you in the right direction.

Nope, this one's a single chamber with serious race sound and decent backpressure, not built for the street. If you need something tamer for a street truck, email us and we'll see what other files might work for your build.

These are digital — soon as your payment goes through you get a download link for the DXF cut files. Nothing physical ships.

The 3.5" Single In/Out Race Muffler Style 1 is $8.00.

Yeah — if you don't have your own CNC plasma, laser, or waterjet, shoot us an email and we'll send over a few shops that can cut (and press/bend) the parts so you can weld them up.

Soon as your payment goes through you get a download link for the DXF cut files. You (or a shop) cut them from steel on a plasma, laser, or waterjet, bend whatever needs it, then weld them into your build. Nothing physical ships.

Yep — these are cut files for DIY and pro fabrication. A lot of the parts are "plasma table friendly" (flat plate, no bends) to make cutting and assembly easier, but you'll need to cut and weld them in yourself, or have a shop handle it.
