3" Straight through muffler?

[BgBlDodge]

Anyone know of a decent sounding straight through muffler that will bolt on to the factory exhaust system? The folks are wanting some more mileage and even though I told them it won't help alot they are demanding one so I figured what the hell. I definately don't want to buy a complete system for them.

Not quite. I know it's a fair amount smaller than 4".
