The motor is about 331 cubic inches. The problem is that the spare tire well drops down in the trunk, and the gas tank occupies the space beside it. I could put dual 2.5's that exit in front of the rear fenderwells, with a couple 'bullet' style mufflers side by side. I know for sure a 3" pipe will route the like original exhaust did, and I can use a sideways mounted flowmaster 3" in/out muffler. Shooting for about 400hp @ the flywheel.


I know with c-bodies the pipes are run over the axle and under the rear frame rails with no problems. Make sure they go past the bumper or your gonna hear em in the car. (droan) Unless that vega is realy low this should still work. As for the newer cars mentioned above, I always thought the split or "Y" pipe after the axle was just a marketing gimick because we like duals so much. Thats why we see them on pickups, no?

I have mechanical Aptitude.
I can screw up anything.
