Review on ๐Ÿ”Š MagnaFlow 5x11 Oval Performance Muffler Exhaust 12589 - Straight-Through, 3in Inlet/Outlet, Satin Finish - Classic Deep Sound by Charles Palma

Revainrating 5 out of 5

Sounds terrible, not a drone

Product works great and sounds amazing. 2001 Yukon XL, no cat, got rid of my roar I had with my Flowmaster, adjusted to normal driving, still sounds nasty when you hit the gas hard. 4 stars because the first one came with a big dent and was sent in for a replacement. The replacement looked great except that one of the welds holding the center tube to the fuselage just wasn't welded on. Instead of sending it in for a replacement I decided to just weld it myself before throwing it in the truck and welding everything together. Very happy with the performance so far. I will definitely focus on magnaflow in the future and not the flowmaster.

Pros
  • Consistent test results
Cons
  • Slightly torn
