Hi There, i have an 07' S2000 (UKDM so it has the F20C) and i have a Toda high power exhaust waiting to go on.
I want to purchase a Toda torquie-kun header and a test pipe before fitting them all in one go.

My question is, would the Toda resonated test pipe be best to get with this exhaust and header setup? or a straight test pipe be best?

pro's and con's of both?

if anyone has experience with this setup, what kind of gains are to be had? I have a pwjdm intake, and will eventually get Hondata flashpro

Before you pick up a header you should budget for tuning - if you can't afford both tune first. As for the resonated test pipe yes. I would sell the intake and pick up a v2 if you just want hp.

I will 100% be getting hondata flashpro to get the most out of the mods.

I didn't see you say anything about an intake, so I don't know what the other guy is talking about, but a straight pipe is better than a resonated test pipe for power, a resonated pipe will be slightly quieter.

The Toda test pipe has a tiny resonator which is straight through. You will not loose power, but you will loose some annoying rasp inherent in our engines. Definitely go Toda resonated. I have the Torqui Kun, it's a fantastic choice and will significantly contribute to a nice torque curve if properly tuned.
