So the 12909 magnaflow fit perfectly into the stock 6.2 exhaust with out any reducers. Mine doesn’t reduce down to 3” until after the rear resonator at the tail pipe.

with headers it would be perfect. With my stock cats it’s alittle to quite for me even with the rear resonator removed. It will be perfect with headers and no cats.

I'm waiting to hear your results after you get headers. I'd really like to get some more volume out of this setup but after doing a 15hr round trip in the truck, I definitely don't want any drone.

I really wish I could hear the 12909 with headers and no cats in person. So far it sounds like the best setup
