Exhaust opinions, pros and cons

I'm at the part of my project where I need to start figuring out what kind of exhaust I want to run. In terms of sound, I don't want anything real loud, just a very deep rumble, throaty sound. For this project. I'm not going for the two stroke dirtbike sound when i'm on the road since I want to be able to drive this to where I wheel, which pretty much cuts out cherrybombs immediately, even though they do sound pretty cool out wheelin. So any particular suggestions on types of and brands like flowmaster 30 series, flowmaster etc, or magnaflow whatever they have would be appreciated. With this I should add that the pipes will be going on to a 1986 chevy 350 in a 95 yj.

Also what is everyone's preference for the exhaust set up. there are so many pro's and con's, what is the best way to go in deciding....dual exhaust (dumping in front of the tires since the gas tank in the rear is offset to the drivers side with only room for one exhaust), dual exhaust dumping over rear axle, both duals out to infront of 1 rear tire, trying to squeeze both duals out of the gap next to the gas tank at the passenger side rear, or just go 2 into 1 and out the back with a factory look?

Anyone who has experienced the same dilemma or anyone who just has an opinion on exhausts please help me out. thank you.

i currently have the 350 in it,, just not up and running yet due to some last minute details (like wiring, electric fuel pump install, radiator)..yea i know its a bit more than a last minute details, it use to have a stock inline 4 cyl. but i'm thinking in advance. the 350 is all stock with a carb. and i think those 86's get around 275 or + hp. In the perfect world i'd like for the exhaust to dump out of the rear, but since i have to replace the tank for sending unit purposes, and maybe center it in the process, i dont know if i should do duals or not. because then i have to find space for the X or H pipe, buy two of everything (cats and mufflers), and i'm a little on the budget. and by budget i mean i'm in college with little income but my 'budget' of no set amount in dollars always seems to stretch with this project.
Long story short, I want the pipes to be put where they are most out of the way from being crushed, at the correct size to optimize torque and power and of course to sound good and healthy. Since I do a lot of road driving, i dont really want it to be screaming, but when i get on it when i'm wheeling i want it to sound like it has some balls...thats why i think a throaty, deep, rumble would be a good compromise. But what do i need to achieve these hopes and dreams? size of pipe? exit of pipe? duals or 2 into 1?

oo..didnt know about such low hp, i got it for the torque but i still thought it had more. kind of a gut check but still good to know. thanks for all the help guys, atleast now i have some direction.
