I don't know if they do. I was planning on running the exhaust througha muffler before they turn up for the stacks. If someone does make stacks with built in mufflers I was unaware!

The problem is I need 6" stacks! I think the muffler will either have to be custom done, or put in before the "turn-up".

I am so on that!
Think that will affect my EGTs at all or with the size counteract any restrictions?

Not even remotely.. That little thing!! I had to e-mail your garage to all my buddies and they are just flippin over that little truck!! You need to weld something to the frame so you can pretty much say that you've built that little truck from the frame up!!!!

Wiggs,
I have a 5" exhaust also. When I first bought the 5" exhaust it was hellaciously LOUD! and droned really bad going down the highway.
The only thing I have found that works well is to purchase a 5" resonator from a place like www.airflowonline.com
Place the resonator as close as you can to the turbo and it will cut about 40-60% of the drone out. If you wanted it even quieter you can put 2 resonators in.
Its not truck or tranny issue...5" is just LOUD!!

D. Wiggs, If your exhaust is resonating a vibration type noise at low RPMs, this seems to be normal w/ 5" and 6" exhaust systems. I believe because the piping is larger, it is stiffer, causing vibes from the engine to travel down through the exhaust system. Mine is pretty bad when idling in gear, the tip wobbles at least 1/2".
