I am getting my zzp shorty header installed with the zzp 3ich down pipe with high flow cat, on friday. I am still running the stock exhaust. I know are stock headers have some restriction and are downpipes have alot of restriction. I just wonder it are stock exhauts are worth changing??

 

Stock exhaust.... I say hell yes. Go duals!

 

change out the piece over the axle that is 2.25 to a 2.5 and you will be all set.

 

ya thats what i was thinking...
