Taking off Rear Muffler?

[rockrawler]

Has anyone just taken off the rear portion of the exhaust? I am not talking about replacing it with aftermarket, I just don't want it to show anymore. I don't know if this is something that can be done without causing it to be excessively loud. I want to take it off and put a nice black tip on. I really hate how GM puts there mufflers on these trucks and the trailblazers. Who wants to see the muffler sticking out anyway?

If you take off the muffler permanantly there is a possibilty you can throw a code. Not sure but its a possibility.

I hate seeing the resonator sticking out like a sore thumb

I'm pretty sure he means the resonator located after the muffler and right before exhaust tip.

I am aware of at least one who remove it and was pleased with the sound.

One of the first things I did was to paint it flat black to help hide it.

Same thing here.. i took it off and replace it with a nice tip no sound or performance or any issues... i then later replace the oem muffler with a magnaflow one.. it sounds much much better with out been load.. and yes.. when you go from v4 - v8 you do notice a sound.. but only within the change it self... nothing bad just a minimal sound that i dont know how to discribe..

Like others pointed out, it is most likely that you are referring to the resonator, not the muffler. Shouldn't be a problem.

What does a resonator actually do?

I was talking about the resonator, I just didn't know what to call it. Laredo, it looks good, I want the same thing but with a black tip and painted black pipe. It's always good to here someones tried something before you get a guy hacking at your new vehicle and find out that it sounds like crap afterwards.

What does a resonator actually do?

At certain engine rpms, there are some resonant freq. that get thru the muffler and the resonator dampens them.

Painting with hi-temp black makes it almost disappear. See link.

That might be the best way to go, it definately looks better painted.

a resonator reduces interior resonance (sound/echo)
