Has anyone tried using the QTech electric exhaust cutout?
After looking at the underside of this newer car, 40th anniversary edition, I am wondering if anyone has had success installing an electric cutout for the exhaust anywhere positioned after the cat. A search yielded nothing.
Thanks!
Thanks!

someone had the badlandz electric cutout.
he dyno'd 10whp with the cutout open. so its roughly equivilant to a catless midpipe. downside is that it dumps straight after the exhaust manifold, so it sounds horrible. the upside is that you can turn it off, unlike a midpipe.

people don't realize how raspy and horrid the rotary sounds at low and mid rpms without the exhaust system. Cutout without a turbo doesn't sound useful especially since they end up leaking.

I agree that it would have to be mounted after the cat, and that would likley only allow maybe 5 AWHP, if the oem muffler inhibits that much HP/torque (guessing on the values there) An un-muffled rotary is a terribly loud but wicked sounding screamer. But considering the price of the Qtech cut out , in any size 2.5" - 3+",
I thought it would be a deal, to use on those occasions where the extra freed up HP would be useful. But since no one here has ever used it, there must be some drawbacks.

5 awhp?
since when did you get all wheel drive in your rx8?
if you are going to get a cut out, put it before the cat, and open it when you really want to scream.
after the cat you'll get 3whp, maybe.
10whp is for a 3" catless midpipe alone. add 3whp for a 3" catback and maybe another 3whp for an intake. still not a lot of whp for the money.

Yeah, absolutely no point in putting it after the catalytic converter. All you are going to do is make noise. Put it before the cat and at least you get a little bit of power with the noise.
