Cat Diameter

[maximusslade]

Out of curiosity, what is the pipe diameter of Marauder cats? I am doing a 4V swap into my Vic. For that matter, what is the cat back diameter as well?

Thanks for your help.

Marauders will be 2.25 from the exhaust manifold, both sides of the front cat, and on the inlet side to the rear cat. The outlet of the rear cat is 2.00. the center H-pipe is all 2.0 except the crossover which is smaller. After the mufflers the pipe is up sized back to 2.25 for the over axles to the tips.
