Hey guys, i recently got a cypher cat back but am now after the upgrade to turbo back but i was wondering if through buying cat back then upgrading would it come with a high flow cat and if not is it highly nessecary to get one. if it is nessecary how much roughly would i be up for?

cheers guys

Wearing bigger running shoes wound’s necessarily make you faster. I am of the opinion, you should make it breather better (cold air intake) first and then think about having a bigger diameter cat and exhaust.

yeh an aps cai is coming straight after

the exhaust does help it breath. infact on a turbo, the larger the diameter exhaust- the better.

Indeed , noting better to extract exhausts would be a turbo, and by the same talking you need a measured balance between intake and extraction.

well done mate,
although the stock dump pipe and cat are the most restrictive part of the whole exhaust.

leave the hi-flow cat converter to last and your a fool, do it once and properly.

The induction box already pulls more then enough air through it. It is not a choking point if the only mods to the car are a cat back exhaust.
