Currently the exhaust exits behind the rear wheels, both sides, right before the bumper.

I got the broken manifold bolt cut off, drilled out and tapped last night. Since everyone keeps saying stay with manifolds, my question is how much performance loss is there in that? Is there a mani that is 'better'...I've seen talk about 'vette mani's but I'm sure those will be hard to find.

My motor is about a 330hp street motor. 600cfm eddy 4 barrel with performer manifold, flat tops 60 over, stock heads with valve job, isky 270/280 cam.

I know it's not am overly hot motor, but a few extra hp is always nice if it can be had. Maybe not enough to worry about if i do some other exhaust changes after she's running.

Part of my concern was that broken stud on mani to tail pipe flange and I have cut to fit plug wires....don't want to custom fit them to manifold and then have to change to header and have it look bad.
