anyone have a cat back set up on thier tow rig? how does it sound? I'm thinking of putting one on my 6.0L Denali, not sure if I should go for the sport or touring set up.

Flowmaster is often the exhaust of choice for the trucks. They have their 40, 50, 60, and 70 series exhausts. The 40 is the loudest. The 70 is the quietest.

That being said; having an SUV, and probably wanting it quiet in the passenger compartment; go with the quietest setup. The long/big interior space of the SUV will allow more sound to resonate inside of it, as opposed to a pickup.

The corsa are a great and different sounding alternative to most out there. I almost went for that on my 6.0HO, but favored a FloPro instead. Exact size and diminsions of the stock muff so I didnt have to scrap the factory mandrel bend 3" SS pipes. Got the sound I wanted, and added a diesel tip and whole thing is kinda custom...but not.

You want the Touring, it is quieter. The Sport tends to be to noisy for long trips.

Corsa exhaust is very well made much better than Flow master. I have the cat back on my srt8 and I really like it. Going to get the same for my Suburban.

I got a killer deal on EBAY for the touring cat back system, (a Chev dealer who is no longer carrying the Corsa line) $400 vs the retail of $1018 should have it in a few days.

upgraded to a set of 22's as well

Just FYI- watch the capacity ratings on the aftermarket wheels & tires. They are often not as high, and I have seen aftermarket wheels break in high load (extreme braking) conditions. Just want you to be safe.

VERY true.

Do you tow the 35' Fountain with the Denali?

Once and a while, & not far, It sits on my hydrohoist 90% of the time.
