Report Anyone built a sports exhaust? in Induction/Turbo/Chargecooler/Manifold/Exhaust Posted December 17, 2009 Thanks Bibs, no special design! we just cut and welded the two 90 deg long radius elbows together. We were also worried about the distribution as well but it has turned out remarkably well, when you put your hand against each outlet pipe at idle you can hardly tell the difference, and visually following the car there is no difference. Not sure how this worked out like this! does yours use long or short radius elbows at the distribution point? After fabrication we thought short radius bends would probably have been a better choice because of the restricted room under the car, but in the end it fitted with no problems.
