What benefit will this exhaust offer for the 00-05 s2k's? Basically if you slap on the piece on without tuning?

 

The dyno plots in post #1 show the performance gain with AND without a tune. Basically, if you don't have a tune, then it just performs like a regular 3" exhaust.

 

The adapter pipe for the Greddy SE dual turned out really nice!

 

I know it's a little late in the design process, but you ever messed around with 1/4 wave tubes or helmholtz chambers? Wonder if that would help with the louder mufflers.

seemed to help a little according to this thread:
Amuse Helmholtz resonator dimensions

 

Really great looking!

Said it before, thanks for getting this out there for the S2000 group. I can't wait to get mine that I can call my own.

 

Is it possible to have the option to order a setup unwelded? Essentially marked with a sharpie on your production jig for proper alignment but then shipped in parts?
That way I could TIG it myself and I'm thinking it would likely also be cheaper to ship in pieces vs fully assembled.

 

@Award78 - I tested several different designs of closed-ended side branch resonators, but they were only effective in certain conditions. They were very temperature dependent, and the slightest change to the overall exhaust setup (TP vs. OEM cat vs. HFC, different muffler, etc.) would throw it all off. The short pipe on the OEM style exhaust is actually not used as a quarter wave resonator, and only functions when combined with a catalytic converter and resonator in just the right locations.

@pmptx - Thanks! We will be installing a mid-pipe and OEM mufflers on your car tomorrow, right? It will need to be one of the prototypes, since I made a boneheaded decision months ago about the V-band flanges that prevents all of the muffler sections I've built from being compatable with my final production design ...

@v2kai - The components have to be tacked together using the jig.

 

Definitely want this.

 

Next Friday. And The prototype is still better by a long shot than the OEM.

 

Can this be had without the HFC component?
The reason I don't want a catalytic converter is because eventually they will all fail
and I would rather have that part made of just stainless steel pipe

I am sure this would be easy to mate to my Berk single
thanks
