Anyone using the MAC 1 5/8 true fit headers? I know they come coated for $299.00 I want to get rid of my Edelbrock TES beacuse of there "dual diameter primarys" 1 1/2 sepped up to 1 5/8. I would like SLP's 1 3/4 too, but for the money the coated MAC's are hard to beat. Plus I was planning on using there off-road cat pipe and cat-back exhaust. I like it cause it all bolts together instead of a slip fit with clamps. Thanks!!
