dumb/front vs cat back

[mupkant]

i'm guessing cat back would produce more flow?

or do they both break even?, i.e same shite?

just get it all the way through, do it right the first time

Well majority of the people do the cat-back first so there might be a reason why, then they do the front/dump/cat later on. But you save on the labour part if you just do it all at once, just my 2 cents.

Cat back will give you more initally as it removes the restrictions in the back half of the exhaust.

Front pipe will give a small gain in response and midrange power but the gasses still have to get out of the stock cat/exhaust.

Catback first, followed by a dump and high flow cat at the same time is probably the way to go if you're on a budget.
