Could your buddy be kind enough to post his pics and videos when he’s got it installed on his truck? Ideally a sound check too on the decibel meter please??

Anyone have pics of the Corsa quad exhaust with black tips installed? Thanks!

On another note, for the 5.3 Corsa says peak 95.2 db for the side exit 21125 and 99.6 db for the quad rear exit 21127.

Has anyone switched from single exhaust to dual exit? I know you can switch the rear valance, but what about the hangers for the left side tailpipe? I don’t think the welded frame hangers are on the left side for single exhaust models. Curious what everyone does.

I’m doing this over the next couple of days and will keep everyone updated and post pics. From what I’ve found, these are what we need:

84751055 (Tahoe/Yukon) or 84751057 (Suburban/Yukon XL) rear facia
84688688 spare tyre shield dual exhaust
23388784 & 23388785 left & right hangers
11589166 x 2 hangar bolts
15672093 x 2 bumper nuts
11548585 x 5 U- but brackets
84682684 (optional) left side exhaust shield (OEM exhaust has a muffler close to the spare but now it’s just pipe and further away)

I’m also having my new facia and hitch cover painted body colour today. Will let everyone know how it goes in the next couple days with all this and my Corsa dual (quad) with black tips.

Thanks for all the part numbers much appreciated I thought be able to switch the fascia and let the exhaust shop mount it but looks like I’m going to need to buy more parts before my corsa exhaust comes in

Did you call Corsa and get these numbers? When I was doing the exhaust on my X5, I made the video below. I used the app Decibel X and set my phone up about 6 feet away from the rear end before cold start. According to this app, my cold starts average about 96dB so 99 wouldn't be that much more for me.

BUT I don't know how accurate this app is so if anyone is feeling experimental, I would love to see this done with the Corsa quad exit!

Fast forward to the end for the results...

Just a heads up for anyone on the fence pulling the plug on the Corsa systems. Corsa is having a sale through the 28th. I placed my order today and was able to get my exhaust + intake (they fixed the figment issues, I checked) for a few hundred off and free shipping. They did say that it would be 4-8 weeks until it shipped out - but no bid deal for me as I’m waiting on my Yukon to get built anyway.
