Ron,

NAPA has what you need in their sales bulletin that is valid through March 31, 2003. The bulletin is called "NAPA Real Deals". Typically there is a pile of them sitting on the counter at your local NAPA store. On page 35, they list the exhaust tubing in the following diameters:
2.5"
3"
3.5"
4"
5"

You indicated that you wanted the 4" hose. The part number for 11 feet is BK 827-5054.

Robert
