1992 3.9L V6 MAGNUM PERFORMANCE

I have been looking all around for performance enhancements for this engine and can't seem to find any. Even the Mopar catalog I have specifically excludes this engine's camshafts. I would also like to add "full" dual exhaust with headers and open flow mufflers & still be street legal. Suggestions please!

one mod i did and i got a great improvment was to the intake 1st i honed the tbi ports
to two inches and put a v8 tbi on and also
welded a 1/8" of alumminum to the backside
to keep the oil from splashing up on the intake whitch creats alot of heat a local
shop did all this for me for $115 I have not
found headers yet but I know sidepipes from a
shelby work great if you can find them I did
at the mopar nats but didn't get a chance to purechas them
