What would it really come down too if say with my combo I made the 358 lb-ft torque at 4100 rpms (flywheel) like in the article you all have seen before. That was done with full 3" exhaust with flowmasters. If I went to 2.5 " What kind of real world torque numbers would be increased ? I would only think mabye 10 at the most and it would be made at lower rpms, what do you all think ?
