Hi All, Looking to get a GMPP?borla muffler for my 14 Silverado 5.3
I thought I seen one with GMPP stamped on the muffler body.
Anyone have a part number for it?
Thanks

I had one on my 06 sierra 5.3, honestly sucked, almost no noticeable difference in sound and i had the sport version.

Thanks for the replies. Guess that I will look into something else. Would like to
pick up some performance and decent sound. The stock exhaust on this truck is
super quiet,like a Caddy. lol

Thanks again. BadgerX does Corsa offer a muffler only option for a 14 5.3?

^ no and no. Lol. Gotta buy the whole kit. That's actually why I like them.

Pick up a borla xr-1 or aero turbine if you're staying stock. If you're going long tubes then a 14" or bigger mangaflow would be good.

love the XR-1s on my 8.1...about to put those on my 6.0 true dual with an x-pipe. 8.1 still has the stock cats and you can hear me coming a couple blocks away
