MagnaFlow XL Series 4 in. x 9 in. x 14 in. Oval Multi-Chamber Performance Exhaust Muffler 13216

Installed this on my truck last weekend and the baffle design completely killed the annoying drone I had at highway speeds. Fitment was perfect with the 4-inch inlet, and the oval shape tucked up nicely under the frame.

Installed this on my truck over the weekend and the exhaust note is deep without any annoying drone at highway speeds. Those internal baffles really do tame the resonance while the perforated tubing keeps things flowing. Well worth the effort.

I swapped out my factory muffler for this one and was surprised how easy it was to fit in the space—the oval shape slid right into place. The perforated tubing does a good job cutting out rasp while giving the truck a deep, aggressive tone. Definitely an upgrade over the stock sound for the price.
