YOUR 1 STOP DFW CUSTOM EXHAUST SHOP: Their exhaust technicians are really old world craftsman. From their precision polished welds to OEM quality custom exhaust system design and installation, Chris' Service Muffler Shop Inc. should be your ONLY custom exhaust system choice. Their pricing is very fair and worth every penny when you consider that their custom system will actually fit, perform and sound the way you want it to. They don't use clamps in their systems, only high quality welds! They even have the tooling to do ball flanges that are virtually leak proof (without gaskets). Their work is so good that several coach level custom builders and classic muscle car restorers (who build high end vehicles to sell at Barrett Jackson) use Chris's Service Muffler Shop. Even better, their shop is Christian owned and operated so you know you can trust them.
