B & G Mufflers Inc.

B&G is a family-run exhaust and welding shop on Northwest Highway in Grapevine. The floor is built to lift heavy: they say they can service vehicles up to 30,000 pounds, which is how RVs, limousines, and buses get in next to cars and trucks. Catalytic converters are the volume work, including same-day replacement when the part is in. They stock Flowmaster and Magnaflow mufflers and tips, and they will custom-make exhaust for a car, truck, or RV. An ASE-certified technician is on staff for emissions, electrical, and engine-mechanical diagnosis (P0420/P0430 and related catalyst-efficiency codes). Welding, trailer repair, light-duty diesel, tires, and general auto repair sit beside that. Custom exhaust is by appointment; they say they will turn jobs down when the bay is full.
