    Part came in on time and fast 2 day shipping. The muffler sounds great on 5.3 Chevy with no cats and a resonator. Minimal drone compared to flowmaster. It’s aggressive when you step on the throttle and quiet at cruise. For me personally I was actually hoping it was a little more quiet because I tow and when you get into the throttle it gets loud. Overall it’s a much more refined and pleasing sound than a super 44. Although you can’t beat the flow master sound wide open!!! Great product!!

    Borla Pro XS

    Don’t let them tell you this muffler is quite. It’s anything but. My truck transformed into a beast. It has a very good rumble and when you get on it , it sounds awesome. I put it on a F150 2019 5.0. Nice thing though when you plain out it settles down to hardly any drone in the cab!

  • Best muffler period.

    I’ve always wanted a Borla exhaust system. The sound is great with no drone. Great product. Great buy.

  • Perfect Tone

    Didn’t want it to roar, or irritate the neighbors, but they do know when the Hemi is awake. Stock was totally silent. I hate that, and now I can hear the deep tone an 8 cylinder should have. Love it, and the installer said I’d love it before he put it on. He sells Flowmaster.

  • Awesome in everyway

    Installed on my f150 5.0, sounds perfect! Ive tried other brands, borla sounds the best and actually can feel more torque down low.

  • Great sound for the money.

    As expected. Worked well with the universal exhaust kit I purchased on ebay.
