We're guessing that your shop probably isn't as great as the Magnaflow shop, but then whose is. Our nice little '79 pickup awaits its fate.We're guessing that your shop probably isn't as great as the Magnaflow shop, but then whos So you buy this old truck, a '79 to be exact, and the guy who had it before thought he would make it go faster and sound cool by throwing on a pair of dual exhausts, 36-inch glass pack mufflers, disconnecting the smog pump, and welding in an H-pipe. Can't say as we blame him 'cause that's the general mindset we grew up with, and pretty much still live with. Well GET OVER IT! We just had it proved to us by Magnaflow Performance that converting back to a single exhaust with a catalytic converter made our engine more powerful (nearly 10 ft-lb of torque and just under 7 hp at the rear wheels), run cleaner, allowed it to pass an emissions inspection so we could get license plates, and even made it sound better. On top of that, the cost for all the parts (pipes, muffler, and catalytic converter) was less than the cost of a factory replacement catalytic converter alone! Who would have thought it! We've skipped the demolition work under the truck to show you the old and the new systems, side-by-side. Not only is the old system worn and rusted, it's all 2-inch pipe. Our new pipes are 3 inches from the Y-pipe all the way back.We've skipped the demolition work under the truck to show you the old and the new systems, Nicely bent and welded, the 2 1/2-inch Y-pipes connect to a 3-inch collector. The left side of the truck was chosen for the system because of better under body and bed clearance, but either side could be used (another advantage of single exhaust). Now if only we could get the bottom of the engine as clean as the exhaust.Nicely bent and welded, the 2 1/2-inch Y-pipes connect to a 3-inch collector. The left sid Here's another look at the junction with the collector and the placement of the catalytic converter. Magnaflow converters use ceramic catalysts and are engineered for high-flow characteristics. Dyno results on new emissions-controlled cars often show gains of more than 20 hp compared to OEM. Prices are considerably less than OEM also.Here's another look at the junction with the collector and the placement of the catalytic If the exhaust system works as good as it looks, we'll probably pick up horsepower and performance. Wait a minute-we did-almost 7 ponies and nearly 10 ft-lbs of torque. Looks good translates to runs good.If the exhaust system works as good as it looks, we'll probably pick up horsepower and per Here's what our truck did in the dyno room.
