Review: Your neighbors will love you again... - I had a flowmaster for many years on my 2005 Silverado Z71. It sounded pretty good until I put shorty headers, trick flow heads and a cam in it and it just turned obnoxious. I kept reading how this Borla muffler was a little quieter while still having an aggressive sound when accelerating. The price was right so I pulled the trigger. This muffler is freakin awesome! The tone is fantastic and my neighbors love me again. For me it was all the good reviews come to life. Very happy with my purchase.
Review: Great muffler made my truck sound better - Bought this to replace two small glass packs the previous owner had put on my truck. The glass packs were load and sounded horrible. This muffler sounds fantastic with a low rumble. It is not loud on start up and when driving at low RPM's on the highway. An added bonus is it does get loud when you romp on it. It is a well build muffler and great for the price.

### ⭐⭐⭐⭐⭐ Great sound
*by D***. on December 16, 2019*

Awesome unique sound on a hemi. Great low end pressure and quiet on idle. Sounds mean when you really hit the gas but not obnoxious. Definitely worth every penny. If you have a ram , get rid of the resonators and add new exhaust tips. You’ll thank me.
