2013 6.0L Resonator help...

[smpldezine]

Last weekend I installed a 3.5" in/out Magnaflow 22" muffler in place of the stock one on my 2013 Silverado 2500HD 6.0L. We welded a 3' piece of 3.5" 309SS from the muffler to the existing flange and behind the muffler we welded it up to the stock pipe. While I was at it, I gutted the resonator and now it drones terrible. Sounds awesome outside but in the cab is a different story. I know, I should have waited but I really didn't think it would have this affect. My question is now that I screwed up, what are my options to fixing it? Buying a factory ypipe section or welding a new resonator in place? Anyone want to trade ypipes?? TIA

Sorry....back to stock?

I love the sound of mine stock. Quiet at cruise and yet when you get on it it has a nice kind of growl.

Best part is that it cost me nothing.

 

ASAP - As Stock As Possible

Learned my lesson awhile back.

I think this is the first I've heard of a 22" being too loud. Most say mine is too quiet. Is yours a round muffler?

 

I didn't know they had a resonator on the Y, I thought all the had was cats. But generally gutting anything is a no no. Especially that far up.

Well on my 2005 1500 Z71 there was no resonator in the ypipe, just the 2 cats which I left alone and added a corsa sport catback which I loved. Instead of dropping 1k again on a catback, I added the 22" magnaflow (#12909). I think it would have been the perfect sound if I didn't gut out the resonator. I think stock ypipe is the way I have to go back or a Vibrant resonator welded in? In the Y, there are the 2 cats, 1 on each side and right after the 2 pipes join up there is a small 'bump' in the pipe which is right under the passengers feet that holds the resonator.

Oops. That "bump" ain't no resonator. Resonators are near the rear of the exhaust.

If you are talking about the 3rd cat looking deal that is at the end of the y pipe just cut it off and put a piece of pipe there. That's what I did with a magnaflow I think it's a 22" also.

That is what I am talking about .. this solved the drone in cab problem?

When i installed the muffler i had them take it off.

I get a nice rumble in the cab no drone.
