PowerPipe Exhaust for slant/6

slantsixness said

Your small pipes dump into a pipe that is extremely too big...You made no attempt to streamline these pipes to the larger pipe creating a lot of turbulence...I think you will find you have killed the low end power of a slant six but only track times will tell you....

Agreed. Those pipes look like crap from a flow standpoint. It seems like you have some talent with welding,why not try and make something like a short tube header,instead of this power pipe crap? The stock manifold will almost certainly have better flow charicteristics based on design alone.
