Could you guys give me your thoughts on this exhaust pipe we built. Im just not sure if its to restrictive since its not mandrel bent. It fits my 3.5 inch colectors at the headers and quickly reduces to 3 inch all the way through to the flanged X. Is it possible to send this peice to someone and have it duplicated in a mandrel pipe? The engine is a 540 making 650ftlbs.

Thanks Rich

If you're going to make an x-pipe, keep the collector diameter constant all the way to the crossover. The collector reducers represent a 36% reduction in cross section.

What he says! smile.gif For most 'normal' bbcs, it might be fine, but for a 540, ...naw.
