Hey Hillbilly,
I will be putting it in this weekend. No NAPA around here so I ordred one from fleet filter and it was 28 bucks or something like that with shipping.
I found the clamps at Homedepot but also wasted about 2 hours trying to find heating ducting or piping that would fit. 4" is not 4" on all that stuff. Don't buy any of it.
While looking for some air brake line for a heat exchanger I am building I found the pipe. Finally. Don't waste your time stopping by 7 different exhaust shops...even if they say custom....because gaurantee they won't have it.
The place I found it was a Big Truck shop. They sold it by the foot but they cut me the 3" length I needed and it was only 6 bucks and gave me the rest I'm sure I will find a use for.
So with the clamp, the pipe I FINALLY found, and the Filter it was around 40 bucks. Again Hopefully my looking saves you time, but if you have a napa go pick up the filter and a clamp, then just call around for a BIG truck shop and bet they will have one. They have stuff for Stacks as well and it was all very cheap.
I will let you know how the install goes but looks easy enough...Not as fancy but saved me about 100 bucks over Dales...But then again I drove around a lot and his is built a lot better than what I'm throwing together. If you have the money and Have to drive around a bit I would say his is worth the money. By far the cheapest filter set up you can buy out there and I hear he is a really good guy.
