From the Header to a Y pipe to a turbo muffler or glass pack then out the back. If legal in your state.

That about all you can do with the 258 that I've found. Doesn't sound like a V8 but sounds alot better then stock.

I got a 20 inch or so magnaflow on my 4.0, and it changed the sound a lot. From what I understand, the longer in length the muffler chamber, the deeper the sound. Also, it's a flow-through.

My 258 has a 20 inch or so glass pack and it sounds good for an I-6, mine is a stock motor with stock exhaust manifolds so headers should sound even better

I used to run a 3 chamber flowmaster on my 4.0 which sounded pretty nice.

i'm running a dual outlet header, to a Y, to a flowmaster 40 series. it sounds nice and throaty while accelerating, but quiets down nicely at speed (which is my personal preference). if you want louder all the time, i hear the single chamber flowmasters are nice and throaty as well as glass packs.

Depending on your free space, a nice trick is to run two glasspacks back to back.

http://www.thrushexhaust.com/pdf/thrush.pdf

The forward unit acts as the muffler while the second acts as a resonator pipe which will help smooth out the exhaust pulses of the 6cyl.

In your case the dual outlet turned around to accept the dual outlet header with another behind it would give it a very deep tone, not effect flow and turn heads under heavy load.

Shoot, When my exhaust broke during a trail ride it was running open at the manifold and it sounded like a cigarette boat at idle

It was way to loud though lol

change the size tubing, smaller tubing usually gives a higher pitch sound. the last foot or so affects the sound too, if you go from sat 2.5 inch to 3 inch using an adapter, you will have a louder exhaust, the opposite is true if you go from 2.5 inch to 2 inch in the last foot of the exhaust tubing. Like a trumpet.

From what i have heard, having just the muffler as the end of the exhaust, no further exhaust tubing from the muffler seems to sound the deepest.

I dont know why this always comes up about exhaust. Glass packs will make an inline 6 sound like a Honda if you want deeper exhaust than get wider exhaust pipes and use NOTHING but a flowmaster in my opinion no other exhaust comes close to the sound and performance of a flowmaster.
