Ecotec swap with new exhaust, new dyno and drag!
#42
New setup is 4-2 upper header section with 1 5/8" primaries, v banded secondaries that go all the way under the trans and over to the stock cat back flange location and merge to a 3" v-band and a 3" exhaust with Vibrant ultra quiet resonator and Borla oval muffler.
Due to matching the cylinders unevenly (1-3, 2-4) the car now sounds properly good.

I eventually went with the 1320 Performance Polaris Slingshot shorty header because it has 1.75" primaries and seems to be a higher quality piece. I don't think my $500 engine with stock cams is going to care much.

How do the dyno numbers supposedly compare to a 4-2-1?
