1992 Trans Am vert LB9 wants increased performance
I am looking for some simple changes to increase the performance of my 1992 Trans Am vert with an LB9 engine in it. The car is stock except for the hood and wheels (still have the originals for both) so I don't want anything that would require major modifications (want to try to keep it as close to stock as possible). Any simple modifications that would increase the performance would be greatly appreciated.

Headers, good catback and an adjustible fuel pressure regulator will give you a nice increase in performance.

I would go with a nice se of coated hooker 2055's Still emissions compatible and will probably outlast your car

The 2055's are a good header, I am running them on my GTA, I am also running the hooker catback as well. check my sig for a sound clip of it idleing.
