A s Pete said 2 1/2 twin is the right size..
Just for tech.. I had single 3" on my turbo engine..Left there from old N/A engine...
It made 370 rwkw before there was no gain and back pressure raised very quick with boost power levels...
I'm NOT saying single 3" is better but my thoughts are 2X's 2 1/2 pipes will flow atleast 350 kw..
Yes N/A is different to forced induction.. But the flow is still required ...
2 1/2" twins over single gives better tone, less drone, better less restrictive muffler efficiency...
So fitting twin 3" is way too large... Unless your building a 500+ h.p engine...

you do realise Dyno's are tuning equipment! Not accurate. Also, there is more to performance than outright power. See xcabbi's signature for details!

Yes i nudeqstane that but it appears as though it's some 4 both. I will have 2 c if there is any dyno sheet 4 it as this was the base reading taken b4 being blown..

Can we have that again in english?
Have you got dyno tests with the torque curves of both exhausts before and after? Of course I'm assuming you changed from one exhaust type to another?

Lol sorry mate using my phone. It's my brothers car it was only ever dynoed once n/a and that was with the Di Filippo already on. I have 2 c if he still has it i know it, not 1 2 hold on 2 now thats it's 542 rwhp lol but he might still have it laying around.
