Quick Muffler Question/Opinions Wanted
Hey guys, many of you have seen the thread on my current exhaust system. Well starting a day or so ago it started to develop a rattle when sitting at lights, stop signs, etc... So i crawled under and started banging on things. Turns out the rattling is coming from the passenger side muffler. I know cats go bad as well so i checked and am very sure its coming from the muffler.

So Jegs said i can return it, but im wondering if i should just get another one or try a different muffler. The labor on these wont be much at all since they are so easy to get to, so im not really worried about swapping 1 or 2 of them.

Im between another Pypes M-80 or a set of Moroso Spiral Flow mufflers. Has anyone had experience with the Moroso's?

M-80 Muffler:

Moroso Spiral Flow:

Im open to other suggestions but need to keep the same 4" body diameter and about the same price of around $50 each. Oh and you can slightly see them from walking up to the Jeep, so no cherry bombs! Black or Stainless only please :D

Re: Quick Muffler Question/Opinions Wanted
Do these mufflers have a deep sound to them? Or ar they loud and raspy?

Re: Quick Muffler Question/Opinions Wanted
Its fairly deep right now but drones like a B on the hwy. I think once the tips come out of the side it'll help calm the in cabin noise. I read on LS1Tech that the Moroso's are a bit more refined sounding and reduce drone. I think im going to give them a try. Im uploading a video I just took a bit ago of the current exhaust
