Whats A Better Buy?

[tezflow]

Hi guys,

I'm just about to put a full 3in exhaust on my r33 gtst. I have been looking around and have come across two different types of dump/front pipes, one is just your standerd single dump/front pipe and the other is a twin dump/front pipe. I was just wondering if anyone could tell me what the main performance differances are and what is a better buy?

WEB SITES TO THE dump/front pipe THAT IM THINKING ABOUT PERCHUSING..

the split system works well because it seperates the wastegate from the exhaust wheel gas, therefore you get no or little turbulence. its not really the same if you compare it to extractors, but where the wastegate pipe connects again is important, as if its too early, there will still be turbulence. these split dump/front pipes provide more hp and a better dyno curve over the open/bell mouth dump/front pipes

taken from the thread that you linked

apparently from what i understand the further back that the wastegate pipe rejoins the better. i think there is a thread discussing this topic around somewhere if you search.

a lot of people on here will vouch for batmbl's products (myself included), and that split dump looks awesome.

Split dump pipe is worth it.

Ok fair enough...I was just wondering though if the difference in performance will be noticible between the 2?
