electronically controlled muffler? ID please?

I saw someone put up a video of this switch type thing that was attached to their pipe. I was wondering If anyone knows what that is called, has any reviews / opinions on them and any idea how much they cost.
Thanks!

 

I remember seeing this too...like a y switch that let the driver turn on supah gnar gnar loud exhaust or stock......

08 taco with electronic cutouts

 

Yep all of you have the right Idea, thank you! I think this is superb however It leaves me some simple questions like about how much does it cost or, should you drive with the manifold closed for very long etc.
I would think this isn't typically GOOD for the truck but If it's okay to run just until outside of a neighborhood or for a morning remote start warm up then I'd be very much inclined to proceed further with research.

 

bump anyone know where I can parts for this?

It is more useful for hotrods and musclecars than a taco. You'll have little to no backpressure, so less low end torque. I learned with my mustang that neighbors don't care for them either, but pull up next to a little rice rocket honda, open em up, and let em hear 450hp dumped right after the headers.... pure sex!

 

^ this.

Mostly ricer's use exhaust cutoffs around this town, and it doesn't matter what they do, it still sounds like their driving a damn weed-eater. But my next-door neighbor has a 2008 Corvette Z06 w/dual cutoffs and it's a beast. Your truck, your rules... it's inexpensive but IMO, not a Taco mod I'd do.

 

Lol thanks bud. I always laugh at LMGTFY. I feel like a retarded kid being shown how to turn a page in a book.

 

The cutouts are really useful on turbocharged cars. I had a big turbo SRT-4 and it benefitted greatly from the cutout. Our vehicles would lose so much backpressure, you would actually be slower until the very top of the RPM range.

I always wanted to see this built into the muffler itself.

Or this Australian company does it as well;

So apparently someone neg repped me for this and in the comment it said "hahahaha"

What the f?

I got one block, one, and your gonna neg me? Jeeeez..

 

im diggin these cut outs.. ive never heard of them before. I think they sound the best on V8s.. idk about the Taco tho.

if the GF gets her Challenger.. I'll definitely be throwin some on it

 

I feel like I got into the way back machine. They were doing this in the 1950's on real hot rods.

 

Illegal in most states, although since you live in Texas you're probably alright.

The only people I know running these are 500whp honda's lol

 

im running a QTP 3in electric cutout.
its dumped right after my turbo on my down pipe.
sounds nasty when its open and the turbo is spoolin.
