Reading on this forum about the huge variety of aftermarket exhaust for the S2000, I am interested to know the difference between them. I am not interested in noise or drowning sound or looks. Just why would one make better Bhp then the other. I am asking this cause I am in process to have one made custom for the S together with a test pipe. The reason am not getting a ready one as the cost of shipping to my country is economically irrational not to mention import duties and taxes on arrival. I would go for a single as that

 

 

PLEASE

 

I have a friend (Ph.D at F*RD) that spends much of his time designing intake systems, and tuning the resonance frequencies to optimize certain parameters of engine performance. I have got to believe that the good folks at Honda have such people on board too, so modding a component as critical as an exhaust system for power gains without compromising something else is well out of the realm of shade-tree mechanics now I'm afraid. Any shop can design one to save weight (single pipe &/or exotic materials) or even sound different (trial & error, unless you just want LOUD )

Just my .02

Thanks Brian

Any others ?

 

I believe someone on the forum had a muffler shop replace the mufflers with straight piping. Same with the resonater. At the very least it saves weight.

Do you know if there was a performance increase or a better throttle response.

Another question would be, What is the diameter size of the stock piping Vs Aftermarket. Pros & Cons about the width ??

 

Well, you're obviously willing to experiment. I'm not sure how your shop plans on making the muffler part of the exhaust or do you plan on just adapting one you have? If so, I would try to find stainless tubing to use as pipe and hope your shop has a mandrel bending machine. Just make the split at the center nice and even and don't put more turns in it than you have to.
