custom exhaust manifold

Well, it's good to see tha that "franken - header" worked for you. Any Idea why your shop opted for a log style manifold instead of doing something along the lines of a 4-1 header?

With the 4-1 design, the o2 sensor could still be located at the collector, and depending on the rest of your exhaust system you could see a nice little HP gain.

this vehicle needs two cats, one near the engine to get really hot to deal with NOx, and a 'regular' cat.

i did not want any used components on this vehicle, as i will drive it till the wheels fall off therefore i wanted something a little more reliable and long lived.

this manifold does fit the rest of the factory system, so i wasnt too worried. it has larger internal I.D. then the cast manifold, though yes, a 4-to-1 would have been much better. i think they were lazy, and didnt give a shit. as i mentioned earlier, if i was there, it would have been different.

*UPDATE*

the damn thing is bursting at the seams!
in other words... the fugly welds are failing.

is there no craftsmanship left in this world? no pride in what you do?
next time, I DO IT MYSELF!
