True duals with SFC'S

I am planning true duals and i will need SFC's(i have t-tops) in the future and want to know if they are compatible.
I have hooker super comp LT's and will put a 3" cut out behind each collector, from there run dual 3" pipe back to dual magnaflow's underneath where back seat floorboard would normally be (gettin custom floorpan for clearance).
I will also get a new torque arm to go with the SFC's(brands unknown, suggestions?) will these create any problems with clearance?(already lost 1 1/2" - 2" with the hookers)

I would think SFC would be a great idea with true duals. If you get boxed ones the weld along their entire length, you can reroute all the sensitive lines next to them and out of the transmission tunnel. This is just my idea though I dunno if its praticle or not.

I would think dual 3" is too much for a TBI 350 unless you really spin it to hell. Maybe you should look into dual 2.5". Magnaflows are also stright through so they would flow more than a similarly piped chambered muffler.

The only reason i was gonna go with 3" is that i will upgrade to a 400 or 406 after not too long and don't want the exhaust to be a restriction.
How much ground clearance would i lose with something like that?
Anybody on here running this combo?

3inch kinda borders in the scrape zone unless you getto modify your floorboard "IE, BFH".
2.5 should provide plenty of flow for 400+cu monster. Another plus to running 2.5 is the clarance with the suspention on the rear end you know the bars that >< on each side, unless you plan on dumping before the rear you migh squish the pipe on a good launch.
