i looked and couldn't find a 2 1/2" manual cut-out, BUT i did find an electric one for about $150 each, which should save you about $200

The cutouts allow you to go open headers with minimal modifications to the exhaust.

Drive your car to the track with the full exhaust, and then on the line, switch over to open headers with the pull of a cable or push of a botton.

If you are going to do it, go with the electrical. I've seen too many problems with the cable activated ones not sealing all the way.

So do you have 2 exhaust systems, one with a straight pipes and one with muffled pipes? And then there is a valve that seals the flow to the muffled pipes and opens it to the open ones??

That's cool

The cutouts are usually right after the collectors. When they are open its like running open headers with a small extension off the headers. With them closed, the exhaust gasses continue on their normal route through the mufflers.

C'mon, get under the car and open them up you pansy. Just Kidding.

I bought the kind that you have to open yourself, I couldn't justify the expense of the eclectics. And I wouldn't want it reducing to a 2" diameter from a 2.5".

Hey guys I'm going to run my cut outs right after my X pipe, I bet it sounds cool.

sounds just like running without a muffler...

Not sure if its worth the cost....run Flow Master mufflers and forget the cutouts...I have had them and they can be a problem sealing then your car sounds like it has and exhaust leak all the time.....and thats not cool!
