What would your choice be for bolt-on a cat-back?
...and why.
I have sold my blown Avalanche and replaced it with a 2011 Ext cab 4x4 Sliverado. I don't plan on getting too extreme with performance mods on this truck but mod #1 has to be to make it sound like a V8. Right now, if the radio is on, I have to look at the tach to see if it's running.
I would like a bolt on stainless steel cat-back system that I can put on myself. There isn't a shop anywhere close to me that can do mandrel bends and I want the longevity of stainless pipe. My goal is not to make a hot rod out of this truck but I would like an aggressive sound during acceleration with out much drone at cruising speed.
I'm not willing to spend the money for Corsa or Borla. I do want dual outlets but haven't decided if I want them out the back or behind the tires.
I probably won't buy from Ebay but it was easy to find links to the systems that I'm looking at:
Flowmaster

Magnaflow

Gibson (although, I would go with stainless and this link is for steel)

Magnaflow but I'd just save the money and buy a muffler. the rest of it is just pipe that your truck already has. But that's just me. I replaced all the piping from Y-Pipe back with a resonator and Borla XR1 for a fraction of the price of a cat back.
Id go magnaflow

So ya lose the Av and you forget all your friends from those forums, huh?
I had the Gibson Dual Extreme on my Av and liked it a lot. The idle wasn't too loud, but you could hear the exhaust when going down the road and it sounded great under heavy acceleration. There was zero drone. I bought the aluminized system and it rusted out at the clamps behind the muffler in about 6 years. If you go with the Gibson I'd suggest you get rid of the clamps and have the pipes welded together at the earliest opportunity, even if you go with stainless.
I've currently got a Hooker Max Flow large body 3" muffler on the Av and I'm probably going to dump it. It drones way too much at highway speeds (even with a 14" glass pack in front of it), from 1600-2000 rpm. It's worst at 1800, which is at 65 mph in my truck. Funny thing is that I bought two, sold one to Chevyfan, and he loves his. He says it has no drone on his truck. I'm going to have to go for a ride in his truck at Bratfest this year.

The Gibson and Magnaflow cat-backs have been the best-fitting systems that I've put on. Some of the others, including flowmaster and dynomax, didn't fit well and were a PITA to install. Especially if you're concered with how good the hangers are, and how well the tailpipes line up & exit.

I think (but am not 100%) I'm going with the Magnaflow. It seems to be a quality product at a fair price. I do like the behind the tire exit of the Gibson and FM better for towing but I don't tow often. I do insist in dual outlets on different sides of the vehicle, that's the old-school in me.
You bring up a point about clamps vs. welding. I don't know anyone that welds with anything but mild steel wire or rods. I'm thinking that would cause a weak point as far as rust. I think I'll buy some SS clamps if the kit doesn't come with them. They are available, any thoughts?
