I wouldn't expect any of those cars to react the same, since none of them have VTEC, and they are all either V6's or turbos with VERY different power curves. There's more to exhaust tuning than gas flow and sound.

 

Here's my car with a full tune and VTEC set at 3800 RPMs before and after adding a resonator.

 

I think the exhaust looks great! With a lot of "canister" style exhausts floating around the forum, I don't understand why this one gets so much hate. I think the helmholtz hanging low actually adds a nice touch to the exhaust. As far as power, I would love to see some dyno's. I really don't think the helmholtz will affect the power too much (if at all), especially with the mild gains you get from exhausts.

 

Of course. It is not easy to make a system for the s2000 that yields significant gains while controlling the overall volume of the exhaust. Most companies are able to produce exhaust systems that give you the most power. In return, you will need to invest in the ear plugs as well.

Our goal here is to do both. Find the best medium. This is something that the s2k community wants. By doing so we must control many variables such as.
Pipe thickness which is set at 3"
Pipe thickness
The bends and where to place specific bends
Type of resonators and muffler designs.
Placement of the helmholtz pipe, Length of the neck, Circumference of the perforation, and the volume of the chamber


In addition, We also measured the tendency in which gas flows throughout the system. As you may know, gases are released in pulses and not a continues stream(which would make our lives a lot easier in tuning the acoustic characteristics of this exhaust). We have taken all these things into consideration before making any of our exhaust.

Do you have any cutaways of the s2k exhaust in production?

 

wow just read all of that. hummmm

 

To put 15 pages into a short summary. The customer was complaining that our exhaust was too quiet. He proved to us that the helmholtz is functional. The OP is no longer complaining because of this fact.

Same exhaust.

havnt gotten around to recording a sound clip but ill try and do it this way.
the only thing i have to record with is my phone so i hope thats good enough

i do wish they tucked the extra canister up more, but the look of it is kinda growing on me.
in total it weighs 33lb, the resonator part weighs about 11lb and the muffler weighs about 22lb
compared to the invidia which weighs about 19lbs

 

is the tip is pointing down in the picture or is it just because of the reflection in the muffler?

 

I have this on my car as well. The tips are straight. I had to adjust my hangers to get it tucked in a bit higher. It is the quietest 3" single thus far.
