  1. Hey everyone! Looking to get some advise on my exhaust. I recently had a Flowmaster Super 44 installed on my 2019 Silverado 5.3L. It's a single in, dual out (dumped). When installed the shop also cut off the flapper that is in line before the factory muffler. While I like the overall sound I'm not a big fan of the popping sound it's making when I let of the gas and start slowing down. Is there a fix for this?
