Can anyone tell me what exhaust system is used on Nascar Truck. Is it a dual catback or single. What size pipe used. What muffler is used(flowmaster?)? Any information would be greatly appreciated.

 

It is a stock system just like all the other 98 F150s, 2 1/2" pipe in and out. The only difference is the Rouse split tip. The only performance items on this truck were the FOU1 computer code which was just a little hotter than stock and the 3.73 rear end which is not limited slip. The yellow sided tires are one size taller than stock.
