Car-x was originally a Muffler and Brake specialist. When we bought the franchise it was Car-x Muffler and Brakes. We bought a bender and had overhead torches available in each bay and had a mig welder. We also bought and stocked about $20,000 worth of mufflers, converters, direct fit pipes, and assorted exhaust parts. We found out the first year that that model would not work. We no longer stock anything but a few basic mufflers, converters, stainless steel tips, and some straight pipe. We still do exhaust work and do some custom exhaust mostly duals on pickup trucks.
