i actually have the devil horns from needswings and by the time you purchase the elbows, the reducer for the driverside, 2 lengths of 3" tubing, a length of 2.75" tubing, 5 clamps you have saved maybe 20$. for that price ill let rob do all the work and ill just do the install!!
also remember if guys like rob cant make a profit then theres no reason to build dual cai's mani's adj fuel setups supercoolers ...... i think you get the idea!
