necessity of a high flow cat?

[ninzee]

hey guys just wondering if a high flow cat is a must to a good full exaust and what sort of power will i be loosing by using a stock cat. the exaust consists of 2 1/4 extractors and a 2 1/4 catback for a D16A8 CRX all stainless steel mandrel bent.
cheers

yes a hi flow cat will make a difference

There are too many variables for someone to tell you how much power you would gain with a high flow cat, but a high flow cat is definately necessary if you want a GOOD exhaust system.

just curious i have a titanium catback exhaust, is it possible for me to get a high flow cat? cause i heard they can't weld steal/SS with titanium or something along those lines

[geeang]

They could easily just weld flanges on the cat so that it bolts onto the catback, most Honda's are setup with a cat that is bolted on and not welded in place.

yes get one. the cat is one of, if not the most restrictive part of an exhaust system

thanks heaps guys.. any suggestions i.e magna flow, x force??

On a D16A8, make sure that you have the need for that extra flow capacity. If you are not maxing out the exhaust flow, then the gains from the high flow cat will be low.

just keep it stock
so you wont get pulled over for it and get defected and complain
better spend your money else where
wont make much off a difference anyway

any quality brand such as magnaflow or x force will be fine

wonder how much different between the three

Normal Cat
Hiflow Cat
Decat Pipe

Would be good to see a dyno result
