134

Equipping the proper size of exhaust pipe on your car is important, as an incorrectly sized pipe may lead to backpressure and increased engine heat, which are things that reduce torque and horsepower. The key to knowing whether you have the proper diameter of exhaust pipe equipped on your car is the size and power of your engine. Choose the correct size of exhaust pipe by reviewing your car’s engine specifications.

Step 1

Review the size of your engine by consulting your automobile’s owner’s manual.

Step 2

Review the horsepower of your engine by consulting your automobile’s owner’s manual. If you do not have your owner’s manual, take your car to a professional mechanic and ask that they determine the specifications of your engine.
