I just installed a set of BBK 1 5/8 unequal shorties in my 89 5.0 and as I drove home after the install I noticed a burning smell so I pulled over to investigate and found out that my air tube hose that comes off the H-Pipe into the engine compartment (passenger side) was rubbing up against the #3 and #1 exhaust port header pipe. Does anybody have a fix for this problem because the hoses are preformed
