From doing a bit of a search I see that there is 2 camps when it comes to exhausts
1) Dual with X or H crossover.
Here's the specs of my van....
XD, 302C, Holley 600 vac sec, Pacemaker headers -> 2 into 1, Lumpy cam Unknown specs, std points ign, MSD Blaster 2 coil, Accel plug leads, NGK plugs. Compression tested with bang on 150psi in every cylinder. Engine rebuilt ~ 20,000 k's ago. C4 Auto.
I measured the exhaust and to my disgust it's running a single 2 inch (I'm guessing the std 6 cyl exhaust) and get this.... 1 bank has about a foot long section of 1½ inch. It's just crap!
So it's coming out on payday I can't decide 3 inch single or a dual x (or H) in 2 or 2½ inch. Since it's a van dumping at the diff isn't a problem what would you do?
Any thoughts on what sort of HP I might pick up going from a crap exhaust to a good setup?
Also why is there no XD Post Icon?
