Replacing muffler only

Replacing muffler only 6.2L engine

Seeing if anyone did this yet. Seeing the escalade has 3 inch exhaust I think from factory no use spending 600-1000 for a cat back.

Im going to just replace the stock muffler only and then get rid of resonator and do a turn down behind rear bumper.

Seeing if anyone did this and is the stock cat back 3 or 3.5 inches?

Are you looking for just sound quality? I dont think there is much performance to be had over the stock system. Hell, even stock, our 6.2 sounds awesome..

im going to just take off rear resonator and run stock muffler. Ill just run pipe to the back of the truck hidden behind rear bumper

I just replaced my muffler on my 07 escalade ext with a magnaflow muffler. Sounds good but not loud enough in my opinion. Going to take it back in to get the resonator taken out. It is just slightly louder than stock. I agree though, replacing the whole system for an overpriced cat back system seemed unjustified considering the stock system is 3.5" and is stainless. I just wanted it a bit louder and figured the magnaflow flow through design would be good for a bit more power (not much I know). I did a 3.5" in/out muffler by the way. Can't recall the part number but they only make a few with that pipe size.

I know the resonator takes a lot and with 3.5 stock (havnet checked mine yet it comes in tomm) thats more than enough.


One thing from my trailblazer ss by removing the stock resonator and doing a 4x9x14 was horrible drone. Moving to a 5x8x30 (24 inch long muffler) sounded good not to loud.

I do think the stock set up is offset/center design.

if so here is one

That is the muffler I used.

not to hijack, but Im looking into replacing the factory muffler with a Mellotone, which is a flowmaster knock-off, (just for the sound) and was thinking about leaving the resonator to hopefully eliminate the drone. Is that thinking correct? I know I will get some drone, just trying to get a bit of sound, but not too much drone. Thanx!

Just my opinion but I think the flowmaster sound will give you some drone. If you leave the resonator on it will definitely help. It's purely a matter of taste but I think the flowmater sound isn't right for this kind of truck. Too raspy IMO.
Update:
My Magnaflow has 'broken in' and sounds awesome. I don't think I will take the resonator out anymore as I like how it sounds. I guess after a bit of time the material in the muffler gets packed in and produces a less muffled sound.

the resonator i removed it barly made the truck louder. The resonator is solid inside only a little hole in the middle check it out.

NORCAL, i did the single in and dual out on my ESV with turn downs behind the axle. Dunno if i angled it wrong but it was loud as f$ck. Took it off cuz the kids couldnt hear there movies in the truck. I used the 50 series muffler. Gonna try Borla next....we will see.
