no the only system they make for the dual cat cars is the force II, and ive heard from a few different people that the muffler on that system doesnt sound very good

I have experienced the Force II system in a lot of ways. Right now with long tubes and mufflex off-road y-pipe it sounds totally wicked. However, I have had this system since I bought my car. So, I have also had this Force II exhaust as the catback in the following configurations:
1) Stock Manifolds with stock dual cat y-pipe and stock cam
2) SLP headers with SLP dual cat y-pipe, dual cats, and stock cam
3) SLP headers with SLP dual cat y-pipe, GUTTED cats, and stock cam
4) SLP headers with SLP dual cat y-pipe, dual cats, and 218/224 cam
5) SLP headers with SLP dual cat y-pipe, GUTTED cats, and 218/224 cam
6) SLP headers with SLP dual cat y-pipe, dual cats, and 230/245 cam
7) SLP headers with SLP dual cat y-pipe, GUTTED cats, and 230/245 cam
8) Hooker Long Tubes with Mufflex off-road y-pipe and 230/245 cam
Each step of the way the sound got better. With stock manifolds and a stock dual cat y-pipe the exhaust is very gentle at idle. It only makes noise when you romp on it. I liked this because I could sit in traffic and not draw attention to my car. So - this is obviously a take it or leave it exhaust. Some people like a really nice rumble at idle. The Force II didn't really get that. It only made noise when you got on it. I wasn't a big fan of this exhaust when I purchased it. It gave me the level of sound I was looking for but not the tone. However, this changed along the way. The more I opened up the exhaust the better the tone got. I wonder if flowmaster tests a lot of their mufflers (in terms of sound) on an open exhaust (headers, no cats). I am saying this because the Force II was definitely made for an open exhaust. The difference in sound is night and day (IMHO).

whats a cut out??
When its welded in, theres that pice of pipe sticking out the side, this part has a cover at the end of an electronic butterfly valve type thing over it to prevent anything from flowing through it. This keeps the exhaust going through the whole street legal syste. When you uncap the cutout, you are allowing the exhaust to flow out BEFORE it gets to any cats, mufflers, or piping.....so your going with pretty much open headers. I think that electronic cutouts are better in some ways but the ones where you have the wing-nuts do some advantages....
With the electric valve you could say your going down the highway late at night, noones on the road, you have your radar detector on, noones around, so you flip the switch and suddenly your driving with open headers.......you come up on some cars so you partially close it (i think some electric cutouts you can control how open it is) so its not TOO loud..... you open it back up and your radar detector starts beeping.....a cops near you, so you close it all the way and your legal. You get to the track, flip the switch and open headers......after your done racing and driving back home, close them up. Problem i have read about with electric cutouts is that sometimes they get stuck or something, so my guess is that you should upen them up and close them and open and close them a few times like not even when the car is running....just to keep things from getting stuck from dirt or rust or whatever.
The manual ones you have to get under the car and undo the three wing-nuts. Problems with this are that you cant do it spur of the moment or while driving, you probably cant control how much it is open, and this is only an educated guess......but *** damnit its gotta be hot under there if you drove anywhere and want to uncap it! so you'd have to have some plyers with you and some place to store the cover and nuts......but if it gets rusted or stuck or whatever, all it would take is a screwdriver to pry it open......dont have to worry about wearing out any electric motors or whatever......
btw i am no expert, i dont have cutouts (dotn even have a car) but i have read stuff and learned about them from my father and uncle who both have their childhood (teenage) storys about cutouts :-D lol
