4.3L exhaust system?

im looking for a good exhaust system for my 04 and ive always liked flowmaster. the problem is im having trouble finding a kit for the 4.3L engine and its bugging me. im looking for a single side exit 2.5in system with the new super 40 muffler, i know my car's a v6 so will it still be loud/throaty... or will it not sound good at all? i also like the dual out setup they have, would that be louder/would i gain more power? im getting tired of the stock exhaust and im also looking for some extra power. any input would be great. thanks.

On the blazers/s10's (with the same 4.3) the flowmaster 40 or the ravin z55 sound good. You don't really need to get a whole system. Almost all of the sound/feel you will get will be achieved by just putting in a better muffler. Dual exhaust is worthless extra weight unless you think it sounds that much better...

anyone else have any input?
