Help por favor...lol
Alright kind of a dumb question but is the OE downpipe (pipe between manifold and catalytic converter) on a 4.0l, 2 1/2" or is it 2 1/4 like the rest of the system. I have a cracked manifold, which seems to never happen on these engines
, and I am just gonna go ahead and do the 99+ intake, maybe 703 injectors, new exhaust manifold or header, and just run 2 1/2" pipe the whole way.
I tried finding a diagram of the exhaust system but none seem to help me. Any info would be appreciated
