Electric exhaust cutouts.

Does anyone use one of these. I would like some pics and some links on where to get something like this.
I want the best of both worlds a quiet car sound or a race car sound at push of a button.
Thanks,

Brady Mahoney

I had my car tuned with the Duel N1's on it. I am switching over to the RB catback. I want to use a dump pipe to make up for the flow lost by the RB.

Shouldn't my waste gate control boost spikes? I would think the dump pipe would just make the turbo spool faster.

Does anyone know if the T78 down pipe is exactly 3".
I think it is.

From what I've heard here, there isn't much of a flow difference between the aftermarket systems. Do N1's really flow better?

I don't know for sure. I will have to check the butt dyno after I change them out.

Keep in mind that most of the people using these don't have the immense heat (and unfinished combustion in the exhaust which causes it) of the rotary engine to deal with. I wouldn't mount one anywhere near the engine or downpipe, especially since the body of the assembly is made of 6061 aluminum (melts at ~1,100 degrees).

Most recommend mounting them towards the rear of the car anyway to avoid resonance in the cabin.
