I am wanting to build my own 4" exhaust from the turbo back. I have been thinking about it and have a pretty good plan. Now all i need is the materials. Does anyone know a good place to get bulk exhaust piping? Aluminized or Stainless. Thanks for the help!

Thanks!

 

Airflow is NW based what you save is going to get eaten up by frt. you can get the stuff from NAPA too or any truck supply house. or try these guys www.mandrel-bends.com but there still in the NW ken

 

Kinda related question: I've got a chassis cab that currently just has a big cylinder of a muffler ending right at the back of the cab. Is there somewhere I can order a downpipe and length to get me that far? It's got a very extended frame and I'm not real sure where I want to put the muffler and exhaust exit, but I can figure that out later.

 

I have not ordered from this company, but they seem to have a pretty good inventory .http://www.munnman.com/

 

I like using this company.. http://www.expanditperformance.com/ They have all the bends 45* and 90* they are like 13 bucks.. Great people to deal with..
