Properly welded is superior to clamped...properly being the operative word. I chose to go with a custom-fitted/fabricated system, because you have some input on the bends, routing, hanger locations, exiting, mufflers & tips. $200.00, including shipping is pretty good, but you or someone else has to install it and $100.00-$150.00 is not much to work with, when it comes to your time or someone else's labor.
