OK guys waht is the most restrictive part of the exhaust on a 1989 5.0L LX with a 5 speed?
Factory headers?
Factory H-Pipe and w/Cats?
Factory Mufflers and tail pipes?
If you could only upgrade one part of the system which one would it be?
If you could only upgrade two parts of the system, which ones would it be?
