I had people tell me that muffler was going to be to loud with headers and catless. But I ran the stock muffler with the headers and catless first and the 12909 was just a touch louder than the stock muffler and no drone but sounded better. My 1 year old at the time would sleep the whole way back from the lake pulling 7,000 pounds worth of boat.
I pull a boat too so that was one of my concerns. Well hopefully yours will be up and running soon and I can hear it. Are you on headers and catless Y pipe now in that truck?
hahhaah got damn I hear that. When I drink I can't leave **** alone. My wife used to hate when I drank cause she had bad experiences before me but now shes getting to where she encourages it ever since I mowed the yard and then washed dried and detailed both cars on like a tuesday night with some crown lol

No headers yet. They where suppose to be before the cam but things change. So headers won't be on until Christmas. But I will have that muffler put on really soon. I wish I knew how to weld.

If you have a welder get some scrap pieces of metal and practice. If you have a decent machine and a little practice it ain't bad. I taught myself to mig by playing with a welder and scrap metal. In a few minutes I was making decent beads. Turn the power up and down and wire feed up and down on a piece of scrap, it's all pretty intuitive. If you blow through, turn it down. Doesn't penetrate turn it up.

That's how I learned to weld. I'm using an old 110 mig with flux core wire. They aren't pretty welds but that's what grinders are for.
The overall length of the magnaflow is 28". You could probably cut out the stock muffler, get some 3.5" to 3" adapters, some guillotine clamps, and be able to clamp it all together.

The guy I bought it from gave me some scrap 3.5” pipe but I have a 6.2 so I’m pretty sure I don’t need the 3-1/2” to 3” reducer. I’m Pressure I can get it welded in for around 50 bucks around here

I think they reduce at the exit of the muffler. So 3.5 in and 3 out, somewhere around in there.
But yeah it's super cheap to just have someone do it.
On my 5.3 that's supposed to be around 2.75" exhaust, it gets down to near 2.25 at the tail pipe. Put a 2.5" magnaflow in place of the oem muffler and the flanges on the muffler were decently bigger than the stock piping. In other words the 2.75" exhaust was a little under or right at 2.5 at the muffler area and keeps getting smaller on the way out.
I measured both exhausts with a dial caliper the best I could. Near the Y pipe the 5.3 is 2.75" and the 6.2 is 3.5", at the tail pipe the 5.3 is right around 2.25" and the 6.2 is right around 3"

So already having a stock 6.2 exhaust and wanting headers, should I leave the exhaust stock?
I mostly want headers for the significant power bump, not sure if that's negated with the stock catback.
I wish someone would try to retrofit the camaro NPP exhaust onto our trucks. I mean it's the same motor with the same AFM. With NPP systems you can run headers and it'll still be very quiet with the NPP valves closed
