I'm looking to replace the muffler only on my 04 EXT was looking into either a Magnaflow or a Corsa Touring. Anyone know the part #'s that will fit the best? I don't want to purchase an entire catback will weld and fab it up myself. Want something that flows better than stock w/o the drown or anything extremely loud. I already have a Mustang Race Car which is loud already this is a daily driver.

Corsa touring is the way to go. i have the sport and i still have no drone whatsoever, just a deeper growl. I find the Corsa sound to be clean,crisp and consistent and i find the Magnaflow and the Flowmaster to be a bit loose messy and phlegmy sounding. You can go to the website and listen to what the touring and the sport will sound on your Escalade.

anyone know the actual dimensions of the oem muffler and inlet outlet pipes don't have access to my truck right now I believe it was single in dual out if I remember correctly. Try to match something up that will be a close fit. Don't want to purchase an entire catback...

on my ext its actually dual in and single out. it's going to be hard to find a muffler like this. I did find one that has dual in dual out, so maybe i'd run a pipe to the drivers side.

Here's a pic of the stock exhaust. I replaced it with corsa sport. I love it! Its amazing how nice it sounds but is barely noticeable at highway speeds. Unless you floor it! I can measure it if you want. There was a number on the corsa exhaust itself, maybe that's available separately?
