Mesa Muffler does, Good, Fast, Reasonable priced work. I towed in my 63 Chevy C10 Pickup with a 348 W block motor, no brakes, and not running. Why is that important? Old truck, wrong motor, and can't be tested when the job was done. Mesa muffler did a great job on my custom exhaust running from the manifolds all the way back. The welds look great, the exhaust was tucked up tight, it does not vibrate or rattle, and care was taken around the starter (I can remove the starer with out removing the exhaust and the exhaust is not cooking the starter). I brought them a difficult project and they did the job and did it well. 3 weeks after they installed the exhaust I drove her from Phoenix to Minneapolis without any issues. These guys pay attention to what they are doing and don't just slap on a pipe and muffler with booger welds because its under the car and out of sight. Its nice when guys actually know their job and do it well.
