Review on Enhance Your Vehicle's Sound with Flowmaster 953045 Super 40 Muffler - 3.00 Center IN / 3.00 Center OUT - Aggressive Sound, Black by Mario Portillo

I put this on my 1995 Ford 460 camper van. I noticed an immediate increase in torque, horsepower, mileage per gallon and the fact that it now sounds like a race car is just amazing! The biggest difference is that it can now climb any hill at speed (60-70 mph) without cutting out on acceleration.
