Tailpipe threw a hairball today

[6716]

Kinda freaked me out when I first saw it.

Didn't find anything on it searching here, but on the OS there are a number of threads. Thought I would link back to some of those threads for anyone searching here.

Supposedly, it's fiberglass from the muffler. Doesn't seem to have a major impact on much, except your brain while you wait to figure out what the heck is going on with it.

So, what I'm thinking is (since I still haven't gotten around to the backpressure test yet) if I have the exhaust pressure to push that fiberglass from the muffler out the tailpipe .... the cat is probably not blocked.

looks like the fiberglass from your resonator.. not your muffler... happens to alot of us SS folks...

 

[The_Roadie]

Oh, no!

Lots of people mistake that for muffler fiberglass. It's really your air filter disintegrating, and the fragments being processed by passing through the combustion process and re-extruded through the muffler and resonator pipe holes like cotton candy. The muffler fiberglass is out of the exhaust flow path and can't come out like this.

Spoiler

Of course, I'm kidding.

See ... I make a couple real easy repairs, I start to think I know something .... fortunately you all are ready to keep me humble when I spout off in public.

Everybody I talked to before I posted said "muffler". Can't tell if they didn't know the difference between the resonator and the muffler, or just couldn't believe that I would.

It is fiber glass and comes from the resonator. Did the MUFFLER delete on my SS.

 

[navigator]

did a muffler delete or a resonator delete?

 

[jrSS]

Muffler not res

Muffler not res

How does that sound? Got a sound clip?

No I do not. Youtube does . That's what made up my mind. Sounds awesome.

I was wondering about this for Phantom. I was thinking on putting a new sleek looking magnaflow res and deleting the muffler for a meaner sound. But I don't know if it would work the same on my truck or not. The SS sounds sick with or without the muffler/res, but not sure if we would get the same effect on the I6 LWB.

Jeff do you know if it can be done? Well...let me rephrase that as it can be done, but do you know of anyone who has done this to my type of truck and got the same or close results to all the SS video's?

 

[jrSS]

Never heard the 5.3 muffler delete. I imagine it would sound good tho.

I have the 4.2 lol Wish I had the 5.3 though as I would imagine it would sound better than the I6. I guess I have some research to do

 

[jrSS]

Oh yea. Duh. 4.2 probably sound like a fart can. Lol

 

[Voymom]

Oh yea. Duh. 4.2 probably sound like a fart can. Lol

LOL that is funny shit right there! Maybe I will just keep it how it is, the slight drone of no res is pretty nice, although my neighbors don't care for it much at 4:30am

 

[The_Roadie]

Almost 100% of offroaders get rid of the resonator because it hangs down way too much and gets bashed.

Your neighbors complain about your stock exhaust minus the resonator? Resonator deletes barely makes a difference .. you must have some anal neighbors that you pissed off a loooong time ago

Actually ours made quite a noise difference when we deleted the resonator. I can hear hubby about a block away with the res off the truck. And yes I pissed off my fair share of neighbors, but they will get over it I can't wait to park the ass end of Phantom near their house when they have their house windows down, and give them a good smoke show

With the 5.3 and no resonator, my truck is what I consider very civil. Even when you get on it, it is not terribly loud. Walking around the back when it is idling is only slightly louder than the wife's Impala with a 3.8 (and the res).

 

[Voymom]

Maybe I need to get a video. ours is pretty loud. It has a very deep thunder-ish sound to it especially at idle. When I get on the gas, it sounds normal.

Here is the video...sorry for hijacking lol

Not as bad as I thought from the way you were making it sound. Granted, it does have a little "rattle" to it when it is revved. I'll try to get one this weekend of mine.

I can hear him come about a block away, I think it's due in part that we live in a pretty quiet, country setting without much white noise. Plus I think the way the houses are set up it causes an echo.

I am also basing the noise off of the comments when I was trying to convince my husband to cut the can off, and posters said you can't really notice a noise difference, which was BS But i'm happy with it, I do wish I had more noise to it, I want the big boy to sound pissed when I'm driving through town

 

[Sparky]

Oh yea. Duh. 4.2 probably sound like a fart can. Lol

Yeah, it pretty much does from every sound clip I've heard.

Does not

 

[Sparky]

I meant it sounds like a fart pipe if you remove the muffler, not just the resonator.

WTF is a fart pipe lol....

The little ricer cars with the fat can in the back. I call them fart cans.

 

[jrSS]

When I had the res. deleted on my envoy (4.2) I could only notice the sound difference, besides the drone in the cab. Dunno why yours sounds different.
