3.5" single exhaust options?
 

Time to try a different exhaust on my 07 Avalanche and I'm looking for a 3.5" single system with no luck so far. Stainless Works has a 3.5" system for the Tahoe (which I'm sure I could make work) but I'm hoping there are other options out there that I haven't come across. Anything out there that I'm missing? Current mods are in my signature.

I'd also consider modifying a factory takeoff 3.5" exhaust like my Denali has but so far no luck finding one.

EDIT: decided to try searching for a Yukon XL which should be the same and found Gibson and Mangaflow options in 3.5" just not positive they will fit. Also, like the Avalanche, it looks like a part number difference starting in mid-2008 but no idea what the change was.

After some more searching I found the Magnaflow 16720 3.5" system which is for the 2007-8 Escalade ESV/EXT and Yukon XL Denali. Since the 07-8 Avalanche shares part numbers with the Suburban and Yukon XL I'd imagine this system for its 6.2L cousin should work?

I wonder if it sounds like total shit without the cats. Wouldn't mind ditching the magnaflow for that on my Colorado if it didn't sound like total asshole.

Thanks aurthursc2 that helps a bit. I've lot 1 7/8 longtubes and a 3" y as well and the Kooks are the same PN for the 6.2 in the Escalade ESV/EXT etc. I can't see why the Magnaflow system wouldn't fit. I love my Corsa Sport but it's been on for 150k+ miles and 12 years. Corsa has been great and they warrantied several components that wore out but I'm just ready for a change.

I have to agree with the other guy above, it will sound a bit buzzy or tin can-y if you catch my drift. My friend put a cam in his 07 trailblazer 5.3 to remove the DoD/AFM stuff but kept the stock manifolds and gutted the cats. Left the stock muffler and tail pipe but has the tin/pingy sound under moderate load. He doesn't care because it's quiet at cruising speeds so we left it.

I took the cats out of the Colorado and with the stock muffler/catback it sounded less like a tin can and more like a 55 gallon drum. Worst exhaust sound ever lol. But sounds like magnaflow is still the best option. I prefer engine roar over exhaust noise anyway.

My muffler was rattling after the cam swap so i bought a 4ft piece of 3.5 inch and 3 45's from summit.
Cut off the 3rd useless cat and made my own with a borla XR-1 #40946 and the stock resonater.
Love the sound and the wife gets compliments all the time on it.

Here is my old 6.2 with 1-7/8 OBX headers, no cats, 12909 muffler and the rear resonator cut off and just dumped over the axle. I had a 1 year old baby at the time and pull the boat to the lake every weekend with him knock out asleep. And never worried about a down shift waking him up. It sounded great at WOT but no drone and the tires where louder than the exhaust at cruising speeds.
