Muffler Delete
Just want to make sure that I am not going to do something stupid or mess something up......
I am getting my Tuner next week, and one of the mods I want to do before it goes in is the intake mod, (6637) and the muffler delete for lower EGTs. Now I haven't crawled up under the truck to check it out but is it that easy?.... Just cut the muffler off at each end and replace with straight pipe?

I mentioned doing this to a mechanic friend of mine and he frowned on it saying it could mean a big fine if detected, I live in Florida and we dont have inspections etc... and the DOT dont regularly stop p/u trucks for inspection 
So how hard wood it be to hollow out the muffler and how wood I go about it??????

I couldn't find anyone local that handles/could bend 3 1/2 pipe.. This is the route I went.. Very simple to do.. I bought the clamps but ended up tack welding it in place.

ALL:
Is there a kit to do this? It would be nice to just crawl under the truck, sawzall the muffler off them clamping on a piece of pipe.

Just cut the muffler out and leave it alone. Leave the stock tailpipe in place so it looks stock.

Before my Duals, I had a glasspack put in the stock muffler location from a shop behind me for 130.00 bucks total but he said just for cutting out the muffler and putting in a delete(frowned at here)) was 30.00 bucks. If you didn't want to do it yourself, might want to find a local muffler shop to do it for you in less than an hours time, good luck.

BillyBob, I had a local shop do mine (better welds than I could do) and he just put in a straight pipe. It actually made the exhaust tip level with the ground by bringing it up a bit. The offset isn't severe enough to warrent an S bend (my opinion). Out the door $100, but it was worth it due to the outstanding weld job.

Wasn't there a cheap flow-through muffler option for like $40 or $50 from Napa or someplace?? Hardly seems worth the trouble to gut the stocker if you can get a good flow through for so cheap.
And Tom got it -- you have to cut the bent pipe and rotate it in the clamp to line it up if you go with a straight line muffler or straight pipe.
