How many people's Dual/Dual mufflers have blown the insides out?
I've always heard a couple people here or there saying that they've gone through Dual/Dual mufflers because they blow the inside packing out. They said it just looks like little whispy strands of cotton. I guess I never thought mine did it because I don't have tips on my system and it would all just end up on the ground. But today I did a test fit on my CME tips and started the car to let it idle for a bit. After only maybe 20 seconds of idling, the inside edges of my CME tips already had a bunch of little chunks of muffler packing stuck inside them.
Is there any fix for this or has anyone gotten anything from SLP as a result of it?
Also, do you know which Magnaflow muffler will directly swap into place of the Dual/Dual one?

i think SLP still makes the dual/dual muffer. i know they discontinued their system but when i checked a week or two ago they still had the muffler listed...at least i think it was the muffler?

If the Dual/Dual mufflers blow through time after time (as I've heard, but didn't know if it was true), I'll just put a Magnaflow in its place. I know their mufflers are amazing quality and sound great with LTs and ORY.

Not necessarily what the inside of the muffler looks like. I could care less about how it looks. It's just the fact that the stuff coming out means the muffler is gradually falling apart!

Many people think that they are the same, or at least similar, due to the fact that their outside appearances are somewhat similar. This is only because they were made by SLP, who obviously finishes the outside of their mufflers in the same manner. The Dual/Dual muffler has completely different internals and different flow path. It is a crossflow-style muffler, meaning it re-routes the exhaust inside the muffler to allow some to pass out the driver's side and the rest out the passenger side. It has an inlet on the right side, then and outlet on each side to retain dual exhaust appearance. The 2OTL is a straight-through muffler and has no crossflow characteristics. Plus, it has an inlet on the right, but both outlets on the left (hence the name, 2 On The Left).

meh, sell it and get gmmg then. do the smart thing
that's what i'd do. i'd buy the gmmg, unbolt my dual/dual, put the dual/dual tips on the gmmg and sell the dual/dual with the $700 style tips.

My Dual/Dual system doesn't have tips because I bought it without them. That's okay though, because my CME valence is in the shop getting painted and the tips have been polished and are ready to go on as soon as the valence comes back.

If you're just blowing the packing out but it still sounds the way you want, (and I KNOW you went through a bunch of exhausts to get where you are ) then what's the difference. It's not like it's going to start blowing chunks of stainless out and self destruct!! (Although, with your luck......)
Yeah, I did go through a decent number of exhausts , but they're all sold now.

My first LS1 with a SLP CME started blowing the packing out After I installed my FLP LT's at 6K miles. The car I have now I bought used with the SLP D&D cat back has never had that problem.

My stock DD blew out soon after adding LTs ORY and my first cam. I bought a new one off Ebay and it lasted 6K miles before it began puking it's guts. Found a used one off Ebay for $20 and it lasted a couple thousand before it went. It's very noticeable when they start blowing out as the sound changes and your tips look like a dryer lint trap. The more they blow out the more they begin to resonate and drone inside the car not to mention the exhaust becomes louder and it begins to sound like a redneck glasspack.
