Corsa dB exhaust install on Trucking TimesIncreasing the towing power on your customer’s vehicles is often not a part of most truck accessory store’s priorities. Nevertheless, products such as aftermarket exhaust systems are a great way to provide them with a substantial increase in torque and power that they can experience. At the same time, providing and installing aftermarket exhaust systems can provide greater profits that many stores are missing out on. The misconception is that an aftermarket exhaust system is too loud or requires extensive welding and cutting to install. The fact is, that most systems install easily without cutting or welding.
Corsa’s dB Performance Exhaust is one example of how a high-quality system installs easily, while providing a performance gain and a new sound that your customers will enjoy. This installation on a Ford F-250 pickup, demonstrates the basic procedure on installing a system that took only two hours to install using a lift, and common hand tools.
Once completed, the truck owner enjoyed the deep rumble that the truck produced on acceleration, but also liked how it was quiet on the highway.

The first step to removing the factory exhaust is to loosen the clamp nearest to the inlet of the factory rear muffler using a 15mm socket and ratchet.









Next, the rear muffler and tailpipe hanger mounts are unbolted from the chassis using a 10mm socket and ratchet.







The front tailpipe hangers are removed from the rubber isolators on the hanger mounts using a grommet puller or a pair of pliers.








Once loosened, the stock system can be removed as one piece, from under the vehicle. Then you can remove the rubber isolators from the muffler hangars.







Remove all the Corsa exhaust components and lay them out on the floor in the order that the instructions indicate they will be installed. Then replace the factory muffler hangar onto the new Corsa muffler.







Starting with the Corsa muffler section, slide the 3-inch expanded end of the muffler inlet pipe onto the factory intermediate pipe. The hangar mount is attached and lightly secure the muffler to the factory intermediate pipe with the supplied clamp, using a 9/16-inch socket and ratchet.








Insert the front tailpipe assembly, and one of the supplied 4-inch clamps, and slide them together into the outlet of the muffler. Insert both of the front tailpipe hangers into the corresponding rubber grommets.






Secure the first tailpipe section (behind the muffler) in place with the supplied clamp, using a 9/16-inch socket and ratchet. Make sure to only tighten the clamp nuts just enough to hold the front tailpipe onto the muffler.








Install the rubber isolator onto the rear tailpipe section and slide the pipe into position behind the muffler. Make sure to keep the clamps snug.






This kit comes with a five-inch slash-cut polished tip. It’s inserted into the rear tailpipe and positioned so that it is properly centered. Once everything is positioned properly, go back and tighten all the clamps.









The finished installation on this Ford Super Duty gave the vehicle better towing power which the owner felt as soon as he began driving the truck. The stainless steel tubing and muffler will resist corrosion and keep the system looking and sounding good for the life of the vehicle.
