Will Aftermarket Exhaust from 2011-2014 Fit a 2015?

Will Aftermarket Exhaust from 2011-2014 Fit a 2015? I would think so given how the chassis is a holdover from the 2011+ GMT900 HDs. Does anybody have any experience with this?

Working on this myself. I'm in a 3-4 week hold for the system before it arrives so I will keep you posted. Right now, Magnaflow is one that I found that specifically lists two systems for 2015 HD trucks with the 6.0. I would have purchased but, I had a Magnaflow cat back on my 2012 1/2 ton and it was good, but I wasn't...thrilled. Droned in a few spots while not in AFM mode.

I ordered from Corsa. I called them, they said there might be some slight issues at the tailpipe. I think clearance of that black strip part of that rear plastic chip guard thing at the rear of the fender. I shall see...

Thanks, interested to hear the results. Corsa was the brand I was looking at.

Update:

It's on the truck. Every bit of it fit and clears the body just fine. Got to re-torque the clamps and will take pictures and video.

It's as quiet as stock cruising on the inside 100%. NO DRONE! When you accelerate, you know it's not stock. Outside is where it shines. Quite the growl.

Great to hear! Can't wait to see pictures and video... is it the Corsa Sport model?

Yes its a Sport series. http://www.corsaperformance.com/viewpart.aspx?year=2013&make=Chevrolet&model=Silverado&submodel=2500&body=Regular+Cab%2fLong+Bed&partnum=14790&cfg=609

Here is a flyby of it from the outside. Working on a couple more videos.

Thanks for posting - that sounds great! Looking forward to seeing more pics or videos.

Good to know there is no drone. Corsa makes a quality product.

One other question... how was the install? Did you have to do any cutting of the factory system, or is it basically bolt off bolt on process? Thanks!

I had a Corsa Touring on my 08 VMAX and I loved it. I would love to go with them again but their systems are 3" and the stock piping is 3.5. I don't really want to go down in diameter.

No cutting at all. Unbolt from the flange and take the old system out of the rubber hangers.

Can you verify that the system you put on was indeed 3" diameter?

Huge thread bump, but... is this something you can do without a lift? I don't have access to one at the moment. Also, the Corsa website says 3" but the exhaust on these is supposedly 3.5". Does it bolt up or do you need something to neck down to the new diameter? Thanks!

Bolts right up. I have noticed no power difference (loss) since putting it on. I did mine in the driveway. If you want to keep the factory system in 1 piece, its a bish to fish out from under the truck. If cutting it doesn't bother you, it will come right out if you do such.
