Need quiet muffler for dual set up, 2018 sierra 1500

[joeb123joeb]

Bought a 2018 Sierra 1500 crew cab short box. Came with a performance exhaust. Want to change things out to get as close to possible to stock sound but keep dual exhaust. Any ideas? Would a Walker quietflow ss single in dual out work? See pics for current set up, attached from front to rear. Thanks

Damn that 3rd pic looks awful. What did they do put cement around it?

Yes, a walker muffler should be quiet.

Same with several longer style magnaflow mufflers.

Anyone have a part number for a Walker Quietflow SS single in, dual out for a 2018 gmc sierra 6.2L? Thanks

Happy with my Magnaflow 12909. its single in / out but you should be able to find a dual out.

 

If anything its a little too quiet but better than stock since i can actually hear it in the cab. Of course much better flow as you can look through the muffler vs stock which has all sorts of baffles and tubes.
