Sounds great

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.

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.

It was exactly what it said and worked perfect has a good tone but not anything deafening or pulling load but puts out a definite sound than stock sound

Sounds great on my 21 Pro 4X Titan. All I did was add this and a borla tip and got great sound. I do get a little cab drone but not as much as the Flowmaster I used on my last Titan.

Feels well built, but the welds could be a done nicer. As always with Borla it sounds great. Would buy again.

I replaced my stock muffler with this one on a 04 tahoe. Muffler shop put in a adaptor after removing stock muffler. Outside it sounds good and it sounds nice at higher rpm's (3500+). But between 1900-2400rpm it drones and sound is loud and "boomy" inside. At idle its very slightly louder than stock. At highway speeds too much constant drone in the cabin. Car is a 2004 Tahoe.I am planning to remove it.

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.
