Review: Great muffler, I love the deep rumble. - Sounds great on my truck. Really let's the engine breathe. Very well made and it has increased the torque and throttle response in my my old pickup. Only drawback is the drone in the cab however alot of that may be just my setup as I just put a turndown pipe 18 inches off the back of the muffler.
Review: Sounds good but not too aggressive - Sounds good if you’re looking for a little louder than stock. Not too loud and no drone Just gives a deeper tone. Looks good also. I used it on a 95 Chevy dually with a 454 single 3 inch exhaust. At About $50 is a great price. Can’t buy stock for that anymore

### ⭐⭐⭐⭐⭐ Excellent product! 5.7L Hemi sounds fantastic with it!
*by J***G on December 30, 2025*

Muffler sounds great! I had my truck essentially straight piped with the factory catalytic converters on. I couldn’t stand the droning in the cabin and was looking for an inexpensive but effective muffler. This muffler helped reduce the cabin noise significantly and the truck still sounds great. I would highly recommend this product!
