Default think i got the wrong muffler

hi guys maybe someone else has had this happen. i pulled out my stock muffler and put in a thrush welded aluminized performance muffler. the first few months it sounded fantastic. at high rpm's it sounded like the big block dodges from the late 60's early 70's. i loved it. now when it hits high rpm's it sounds like a vacuum with a rattle in it. it also developed a ting in the exhaust at low rpm now too. it kind of sounds like a high lift cam in ting from the older v8's. everything is stock on my truck...for now....it's a little pricey building a power wagon. ok i got one mod....37 inch cooper discoverer stt's.

Sounds like a baffle inside came loose, the welded series is famous for it.

Looks like its muffler shopping time for you!!

The mufflers with the baffles are junk, flowmaster especially.

The straight through design mufflers like magnaflow or SLP are way nicer

i think you guys are right. i tapped on the muffler with a dead blow hammer and something is rattling inside. since i don't have the mds i think it may be time to go high flow cats and a short bright red glasspack. i think i might go with a single in dual out and have both tailpipes welded together running out the passenger side. just to be different. and yea the 37's fit. i just need a 2 inch lift to use the sway bar disconnect. i think it looks pretty good with the 37's. and i only get minor rubbing on the upper control bar for the solid axle. this is her with the 37's
oops thats just how i feel when i drive my pw. lol
this is her with the 37's. i kinda like it.
