Q:

will this fit a 2016 chevy sliverado 1500 5.3L 4wd

Asked by RONALD on October 02, 2019

A:

Yes, it will not be a direct fit as the factory pipe is 2.5” but any muffler shop can adapt the Borla muffler to the factory pipe.

Very Good Sound

Summit RacingSummit Racing Verified Purchase

BOR-40085
I purchased this muffler because it was the cheapest Borla that I could find. It is a very loud muffler, but with the help of a factory resonator that I left on my 2012 F-150 (3.7L) it is not incredibly harsh. The finish and inside components of this muffler are of flawless quality. (And it has a distinctive Borla sound.) I would definitely make this purchase again. ...read more

Deep and thunderous (stock 2006 5.3 L59)

The XR-1 I bought went on my 2006 Suburban and in the spot the factory muffler was located at. In short, it has a really deep tone, which was what I was looking for. At warm idle, it's not loud or noticeable at all, but putting a load on it/giving it throttle definitely reveals a louder, bassy, and rumbly tone. Cold starts will wake up neighbors, so it sounds great there. It has low pitch exhaust pops (like THUNDER) off throttle that I was ALSO looking for, especially if you lock out gears and let it engine brake starting at 3200 rpm down to 2300 rpm. The pops sound incredible. To my liking, it has no rasp. Only negative point would be some drone from 1700-2200 rpm with ~>30% throttle, but its tolerable. It is pricier than Magnaflows and Flowmasters but it fit every sound point I was looking for. Overall, I'm very satisfied and pleased with how it brings out the deep roar of an iron LS and would buy another if I buy another car/truck with an LS based engine. ...read more

sounds great!!

this for my 2016 for f150 5.0 and it changed the attitude of the truck. Even at idle you can hear the difference, it's bit louder but has a great low rumble to it. When getting on highway it's really aggressive but doesn't have an obnoxious drone. I left the rest of the exhaust system stock when this was installed. First borla but not last for sure! ...read more
