Need some Magnaflow help

Again, it depends on what manufacturer you go with. Some include clams other don't. If you choose one that does not buy yourself stainless band clamps. Try not tou use the typical U shaped exhaust clamp as they kink the pipe and make it real difficult to adjust later on.
 
Well, this weekend I installed my Magnaflow Catback I got from Partshopper a few months ago. It had everything I needed in it, except for some removable loctite (for the last hangar set-screw)....I didn't have any around (of course I had 3 bottles of the premanent stuff!!), so I used teflon tape, I hope that keeps them in....
IT sounds awesome! Well worth it for me :) Good luck...
