Doesnt ats have an exhaust kit on their website? If you wanna be a redneck, go buy some pipe and find someone with a tube bender and make your own exhaust...thats would I would do, but you have to be pretty good with your math to get the bends right.

Well then it depends on what kind of setup you want to do. I'd straight pipe it from the headers all the way to the back. Maybe do a dual exhaust setup. You'll save a few hundred bucks doing it that way. I'd probably use 3 or 4 inch electrical conduit, its really strong stuff.

i put a 3 inch flowmaster delta 50 series on my truck, where the downpipe goes level with the bottom of the truck. then out of the muffler to a T pipe, and out to the stacks.
it is still loud enough for you to hear it, but not loud enough to not hear the radio with the windows open.
before the muffler was installed, you could not hear the radio. with the windows closed!!!

on my 79 i have a 3 inch delta 50 flowmaster connected to the y pipe, and 18 inches of pipe off the outlet to a 45º turndown on it. it sounds about the same, nice rumble, but not loud enough to make cops look as you go by.
the only reason i went with the flowmasters was the thickness of the muffler body.
the 79 muffler is 20 years old, and still i perfect shape.
the best i ever saw out of a muffler on a gas job is 10 years with anything else, so i feel they are worth the price paid for them.

I have changed my exhaust many times but the best sound I have found came from a true dual straight pipe package that someone made out of 2 1/2 inch pipe coming back and 45'd to each corner of the bed into 4 in tips. Keep in mind that the only reason he went with 2 1/2 was because it was a stock 6.9 diesel so your turbo would need probably 3 in true dual or 3 1/2 to 4 in single or y pipe

I just bought a 4 inch Donaldson truck muffler. Its for a semi but I have a friend that put one on his and it sounds good and its a straight thru. It was only $75 which I thought was pretty cheap.

I am going with a 3" single on my 84 F250 4x4 6.9, running 3" pipe from the Y straight back into a Dynomax Ultraflow and dumping it in front of the passenger side rear tire with a 6" tip. I am thinking she'll sound mean.
