Allan, I haven't plumbed Ruby's Magnaflows up yet. Looks like a winter
hibernation project!
I've yet to locate 1 5/8ths J pipes, relocate and weld hangers, and mandrel 'S'bend exiting tail pipes. They'll be mounted side saddle by my valve covers...but being thinner and shorter they'll give me more room and a better sight line for future valve adjustments.
I'm far from being a competant 'wrencher' & 'welder' but this is a can do project for me! When you hear them gurgling at Carlisle 2013 they'll trigger pleasant memories for you and Bobbi.
