custom ypipe dumped before the axle vs duals dumped as well
 
i am wanting to redo my exhuast setup

i currently have macs, stock mac orp, and a dynomouth setup

i am thinking of two things

1) custom ypipe into a muffler and dumped
3" ypipe with dual cutouts, flowmaster collector, into 3.5" piping and a muffler dumped before the rear axle (not sure on muffler yet)

2) duals
2.5" duals, xpipe, single chamber flows or magnapacks, dumped before axle

both setups would have the ball flanges cutoff and the collectors extended slighly with 3" flanges

the ypipe would be lighter, and louder, but the duals would sound better

my question would be powerwise though, both street (cutouts capped) and strip (cutouts open)

any ideas

I've also thought of ripping off the catback and going 3.5" from Y-pipe back, with one 3.5" Flo Pro Twister bullet, dumped. I'd try to squeeze a cutout in there before the bullet. This probably would not work, so 2 cutouts at the Y then.

Might as well do X-pipe 3" true duals.

the dual mufflers would be single chambers or magnapacks

the single would be a 3.5" deltaforce flowmaster or a dynomax ultraflow

man i wish i never had to make decisions

actually thinking about it i probably wouldnt run dual cutouts in the first one, it would flow well enough as is

anyone have a setup similar to this, im leaning towards the first one

Tally, do you know if it's illegal to dump under the car in FL? Not that it's gonna stop me, but I wonder...
