Difference in catback and hi-flow catback

[Jericho123]

Sorry to sound ignorant but what is the difference in a catback exhaust and a hi-flow catback exhaust.

im pretty sure a high flow allows more emissions through so better something but worse emissions but better performance i think. lol sorry i thought i knew it but now i realise that i dont (bike)

there is no such thing.. there is a high flow cat convertor and a cat-back exhaust. meaning that after the cat is where the new exhaust starts.. a high flow cat converter has less restriction than what the stock covertors have, thus a small hp gain.

I want an exhaust set up that will let the engine breath at its best and want every last bit of performace it can give me with the exhaust being really quiet. What can you guys reccomend to me?

headers, if they make them, high flow cat, to stay legal and about 2.5 inch exhaust with new muffler...

um good luck on finding an exhaust that gives the best performance and is really quiet. a new exhaust will always produce at least a little more noise than stock.

silencer is always an option....still reduces your power though, but at least you can pick when to unleash the beast
