More Towing Power With An Aftermarket Exhaust System

Installing an aftermarket exhaust system for more towing power

By Dan Sanchez

The facts are that your towing customers would always like more power to tow heavy trailers up steep grades. So why not make additional revenue selling bolt-on aftermarket exhaust systems? Many stores think aftermarket exhaust systems require welding and special bending tools. But the fact is, most aftermarket systems bolt on easily to replace the factory system.

To demonstrate how simple it is to install an aftermarket exhaust system, we looked on as Advanced Flow Engineering installed one on a Toyota Tundra that tows a 25 foot enclosed camper trailer. This installation took about an hour with a basic ratchet, socket set and some WD40 to loosen rusted bolts. According to AFE, a typical system like this one can provide as much as 21 extra horsepower and 33 lbs.-ft. of torque, which can definitely help getting a heavy trailer moving up a steep grade.

Installation Procedure

 

The factory exhaust on this Toyota Tundra has lots of bends and a restrictive muffler that hinders towing performance. An aftermarket system will allow it to flow more exhaust to provide more power, and add more profits to your store's bottom line.

 

 

 

 

 

 

 

The first step is to raise the vehicle on your lift and saturate the bolts connecting the exhaust to the catalytic converter with a lubricant like WD40. Then the bolts can be easily removed.

 

 

 

 

 

 

 

Using a jack or a co-worker to hold it in place, the bolts and clamps holding the factory muffler to the system are removed and the muffler can be lowered to the ground.

 

 

 

 

 

 

 

Here you can see the difference between the factory muffler on the left, and the AFE performance muffler on the right. The AFE muffler is lighter and less restrictive, allowing more exhaust to flow through and provide more power. But this muffler also has baffling and sound absorption properties that will give the truck a healthy performance tone, without being loud.

 

 

 

 

 

 

The new muffler is lifted into position and is hung on the factory muffler hangars on the vehicle's chassis.

 

 

 

 

 

 

 

The new larger diameter tubing, stainless steel in this case, are attached with the provided clamps in place. Note how the tubing slips over the muffler openings.

 

 

 

 

 

 

 

The rest of the exhaust tubing attaches to the factory catalytic converter flanges using new hardware.

 

 

 

 

 

 

 

Once the tubing in front of the muffler is aligned properly, the clamps can be tightened to hold them securely in place.

 

 

 

 

 

 

 

 

The over-axle pipe is slipped into the muffler and is hung on the factory exhaust hangars.

 

 

 

 

 

 

 

 

Once the alignment and positioning of the over-axle pipe is satisfactory, the clamps are tightened to secure it.

 

 

 

 

 

 

 

 

The final step is to add the exhaust tip. This AFE unit uses a nice black exhaust tip that also enhances the overall appearance of the truck.
