questions about true dual exhaust design

[High Five H2]

So I'm thinking about putting some long tube headers on my H3 alpha. They're going to have to be custom fitted, obviously, because no one makes them specifically for it. There's a place that does true dual exhaust right now the street from my work, and I figure I might as well do the headers and exhaust all at one. I want to put a borla muffler on it. I found one that's 1 muffler with 2 inlets and 2 outlets. Will that work for dual exhaust, or should I get 2 small mufflers? I know space is tight under there and mufflers add a bit of weight. Will there be a power loss? if so, how much?

Any other suggestions? I'm thinking about doing an H pipe and having the muffler towards the middle instead of under the cargo area for more clearance.

Last question: are long tube headers any weaker than manifolds? will they break from offroading?

Judging by the undercab space on my 06 3.5 you're right, it could get tight. Get measurments of twin mufflers and the 2 in 2 out and visualize where the pipes would need to intersect the muffler and if there'll be clearance issues with the driveshaft. A single is no prob but that pesky fuel tank kinda gets in the way at times.:giggle: True duals would sound killer though and a good muffler shop should be able to custom bend one in a few hours.
