### ⭐⭐⭐⭐⭐ 







  
  
    As usual, just the right tone!
  

*by S***F on Reviewed in the United States on 3 March 2020*

Don't get me wrong; I like Flowmaster's products and other chambered-style mufflers. But they just seem a bit too loud for passenger cars. I removed the main resonator and 2 main mufflers on my Lexus GS400, and the drone was just too bad, so I bought this unit and put it in the place of the original front/main resonator. After that, it goes through the 2 secondary resonators and out through straight pipe. The drone now is at a low level, and sounds sweet! Magnaflow's stainless products can be spendy, but as a technician, I've driven many vehicles with their mufflers, and the sound has always been nice. Remember that the length and size of your pipes affects the amount of drone, so you don't need to blame it on the muffler.

    Sounds amazing, better than I hoped
  

*by F***K on Reviewed in Canada on 4 February 2016*

Sounds amazing , better than I hoped :) Great price too >> I had to pay extra to fabricate two hangers , and extend the outlet pipes as this muffler is shorter , still cheaper than buying the direct replacement fit ( although then it's a straight bolt on install in my own garage) >>
