Damn thats pretty cool

 

[Rennat]

would be nice if you could control how closed that butterfly valve is...

 

[T-MA71]

Wow... i want one now haha thats sick!

 

[akito]

nice!!!! I like it.

 

[Facime]

slick as hell! great concept. I wonder how well it holds up over time.

 

[rtrdpenguin]

That is really cool. I'm pretty sure Porsches and some other high-end cars use a similar system, but instead of you controlling the valve with a remote it automatically opens and closes based on how far open the throttle body is.

nice i want one looks fun

 

[tsuper92]

look's like a window motor open's and close's the butterfly

Pretty neat, but I'd still rather have a cut-out at the end of the downpipe and a relatively quiet exhaust.

 

[626na]

how do you do a cut-out sorry newb

how do you do a cut-out sorry newb

its having that butterfly in the exhaust near the cat as appose to being inside the muffler. there are electrical and mechanical cut outs.

New corvette z06 has it based on throttle position, its vacuum operated.

It would be cool(er) to have it opened by boost pressure, with a VSV to turn it on and off. so when its on its only open under boost, and when off it never opens.

this has been around for awhile they sell them in the hot rod market.I always thought it would be a coole idea for sombody to do it on a jap car.It's a cool idea but not somthing I would buy.

It's not the same as the butterfly valves that are mounted in the exhaust. The butterfly closes causing the exhaust to go around the outside of the muffler, acting like a better than stock muffler.

Think of it as having control over if your silencer is in your muffler or not, but at the push of a button.

Cutouts have their issues as well...
