We originally  designed the TR Series in 2008 to solve ground clearance issues on some cars. The unique triangle shape makes for some of the most efficient use of available space. On most front wheel drive cars, the empty drive shaft tunnel is triangular shaped. With TR Series Triangles, the muffler is able to fit up higher into the tunnel without contacting the sides. By placing the muffler higher, up to 1.5” of extra ground clearance can be gained vs. a similar sized round muffler.

The TR Series make for great resonators because they have the same internal volume of a larger round muffler  and none of the ground clearance issues. The result is a great sounding exhaust that doesn’t drag on the ground when ever you drive over a speed bump or into your driveway. These units can also work wonders on rear wheel drive vehicles, where they can be placed in the tunnel on either side of the driveshaft.

• Body Length: 14”, 18”.
• Configurations: Center/Center.
