    30571 - JEGS Dual Exhaust Kits is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Workable I'll start by saying if you don't have a welder don't attempt to install this exhaust. Some connections can be clamped, but some will have to be welded because the bends were not perfect for my application "67 Cougar" The muffler hangers are cheap, I purchased heavy duty swivel hangers from local parts store for $6.00. Come on manufacturer of this kit don't skimp for a couple of bucks. Overall a decent DY kit.
