when having custom exhaust piping done, does having the pipes mandrel bent really that important? how much noticeable difference, power wise, is there between madrel bent pipes and crush/crimp/bent/normal way pipes? im talking about 2.25" piping. thanks!

 

i'm not sure but as soon as someone comes up with hard proof(dyno) i'd love to know myself.!

 

if its crushed/bent/etc it would create less flowage... probably hurting performance..

i remmeber on my SHO.... when the stock Y pipe was replaced with a mandrel bent aftermarket y pipe it free'd up a dyno proven 11WHEELhp. . .
