I should make a video of my open downpipe, sounds like a broken truck, lol

 

For the quietest and most flowing exhaust the cut out is the only way.

Great article:

My setup is fairly quiet. Check out my build thread: https://www.s2ki.com/s2000/topic/855...-build-thread/

In the vid of me running down the track you can hear how the exhaust itself isn't very loud. You hear the dumped wastegate more than anything...

 

I agree with Soul and MissmyS. If you want quiet, go stock or similar and a cut out for when the noise doesn't matter - when you're trying to pop wheelies on the S. My vote goes to Sound Performance boost actuated cut-out. I did not have a single issue and it was opening and closing MANY times in a day. It's as reliable as any turbo internal wastegate. One personal preference is that instead of the cutout quickly closing shut between shifts (< 10 psi) I wanted to slowly close, maybe I can plumb a bleeder valve in the vacuum or something

This is IMO the only way to have best of both worlds. I went quiet to add to the sleeper- "please don't pull me over"- look.

 

What is the highest power someone has laid down with a 70MM exhaust????


The fact that I may have to sell my T1R duals makes me want too

 

I'm running 70mm T1R dual (sparrow)

~12psi
~500hp Dynojet
~450hp Dyno Dynamics

I'm sure this is no where near the "highest" power

I love my exhaust...glad I didn't have to get rid of it!

 

Forget about your exhaust. It's the log manifold that will hold you back.

 

great topic, i'm tired of my 3" exhaust, i will be using the cutout system. would you guys recommend a specific brand? how about this one

 

I recirculated my wg and its super quiet even with the Greddy Tic single

 

Lol I agree.
