Need Part Number for Flowmaster 40 series
As the title reads, I'm looking for which flow 40 series SI/DO are compatible with our trucks. I'm assuming, from searching and scanning the threads, that at most I'll want 2.5". I thought I had saved a thread with which worked on our trucks, but I guess not.

if you dont want the delta flow and want to save your self a little bit of money drop the 9 infront of the numbers... its the same muffler and you wont notice a difference....the delta flow is made mainly for cars, but the muffler sits so far back that it doesnt effect the cab of the truck....
