I have heard about people seeing gains with them when they are open.

There are electric options already available on the market. The problem is that over time the motor will start to fail and the valve won't completely seal.

I spoke with ED about doing a cut out and was told that if i am serious to have it done before i go in for my tune so i can be tuned with it closed (closed/around town/DD map) and open (open/track/race map). I personally would like to do one as well but i have so many other things that take priority over a cut out.

What you could do... is take those small electric motors, encase it in some silicone from tap plastics(making sure the wiring is in place) and to open and close the flang you can use a worm gear. should seal it pretty well. I would cover it in heavy grease so that it won't rust up so easily. You could prob make the whole thing from a heavy gauge sheet metal. but you can work out the whole set up later on.


Thanks for the idea. I think im going to try this out. (ill let you know how this goes.) lol

I run a stock muffler with APS 3.5" exhaust, they cut both ends and flange the pipes to fit eachother and v-band them together! It's amazing the difference when open and closed.

As for placement, dont put it where it will scrape easy and then fall off on the freeway like mine did lol..

got it at Blacktrax in milpitas

I guess what I'm trying to ask is, will I have a higher likelihood of knock(blowing my engine) if my car was tuned open cutout and smashed around with the cutout closed or if I were tuned with it closed and smashed around with the cutout open?
