This forum has been very helpful with me and my truck. I do have a question. I have a 98 sierra with the vortec 5.7 and I went to a muffler shop to buy and have two flowmaster 40 series put on my truck with new pipe from where cats used to be to the axle. Until I can get my LS swap done im trying to get the most aggressive sound out of an almost stock motor. Here’s the problem. Sounds good enough unless you bear down on it then it starts popping like glass packs. Also I can’t see the word “flowmaster” embossed on the mufflers. Given they are flat against one another and welded where you can’t pry them apart but I had lower ranked flows before and the didn’t pop on acceleration. So i am going to get 2 1/2 exhaust no need for bigger but would the small exhaust setup on this truck have something to do with the popping or possibly I’m a victim of Chinese flowmaster knock offs since they are doing that now. Also can someone lead me in a direction of the mufflers I’m looking for? I e heard jones exhaust ,loudmouth exhaust which I heard personally on a stock mustang and That’s what I’m searching for. Sorry for the novel
