      Is mandrel bending a stomper for the exhaust. Local muffler shop is saying it isn't. I was also told by them that my pipes are factory mandrel bent, is that true? I have a 03 limited v8?

      Mandrel bending allows the best exhaust flow. It's the best (and should be only) way to bend piping for your exhaust. Definitely follow Hartman's advice.

      Being that you have the 100 Yr anniversery model, mandrel bent pipe is mandatory IMHO

      Yeah I would think so too especially for what I paid too. I am probably just going to go with the catback systems with the mandrel and not deal with custom jobs.

      Mandrel bends will retain all of the tubing inner diameter throughout the bend. Typical exhaust shop "kink" bends will reduce diameter through the bend. Look at it like this- if you're running 2.5" tube, it will be 2.5" all the way through the bend with a mandrel bend. Non-mandrel will make it 2.25" or even smaller (depending on how tight the bend is). Its kinda pointless to run 2.5" tube throughout the truck only to have it choked down to 2.25" at the bends.

      Mandrel bending is absolutely necessary. Your Ex will die without it. Definitely spend the extra money!
