Alright here is the deal, i just a new (new to me) 2000 GT convertible 5 spd, this is my first mustang that I've owned. I am going to go through the regular mods but I was thinking of putting cutout's on the exhaust until I buy the SLP loudmouth system in Jan or so. Has anyone put these (cutouts) on there car and do they sound bad or just loud, cause loud I can deal with. Any other ideas or advise please let me know

I have been interested in putting cutouts on my car as well, but I have heard information that caused me to decide not to order and install them.
I'm no mechanic, but here is what I've heard.
The point of cutouts is to bypass the mufflers and, if applicable, the catalytic converters as well. By bypassing the cats, you are also bypassing the oxygen sensors. This could cause a problem with the readings that go to the ECU, and the SES light will most likely come on. Additionally, opening cutouts will greatly reduce the backpressure in the exhaust system. From what I understand, this will cause you to lose low-end torque and gain high-end horsepower. Having the cutouts open might not be bad for the track because your engine will be running at a higher rpm during a race, but I don't think they are helpful on the street. They make your car sound plenty intimidating, but you won't be able to back up the threat because of the loss of torque.
Please feel free to correct any of the above information; I stated it as I understand it, and I would like to learn more about the topic as well.

Do it and we will hate you forever! Exhaust cut-out's are for rusty old Chevy Pickups, and full on Track cars, not of street driven Mustangs....they sound like @$$!
what about electric cutouts? I have friends running them on Fbody's who like them and considered one for my car, or possibly for any future GT. The only thing I can see bad is that with the cutout open on the strip, the car wont be used to the extra flow and would probably run just like it always does, just louder. Sure you could drive with it open all day before you go to the track, but that doesnt help for the occasional random blast down the road (admit it, we all do it)

GM’s and Ford’s are totally different animals, with totally different engine configurations. F-Body's sound like outboard motors with their exhaust intact! Cut-outs actually improve their sound. As far as a mustang goes, you'll loose that throaty sound that makes them distinct and it will sound like an F150 with a gutted exhaust. Not to mention that a stock Stang isn't making anywhere near enough airflow to warrant the use of an type of open exhaust and it would literally kill your car at all ends of the power spectrum.
