Choosing the proper diameter of the tubing for your exhaust system is as important as selecting the right muffler. Your tubing diameter choice will affect the sound level and performance characteristics of the muffler, but keep in mind that bigger is not always better. Using tubing that is too large can actually hinder exhaust scavenging by slowing the velocity of exhaust pulses in the tubing resulting in a loss of torque. And torque is what moves the car.
There are many variables that need to be taken into consideration when choosing the correct tubing size for your application, such as engine technology (flat head engines vs 60’s engines vs present-day engines) cubic inch, catalytic converters, head flow, vehicle weight, how the vehicle is driven and numerous others. Light to moderately modified street applications will generally use 1-5/8" to 2-1/2" depending on the engine displacement, power output and the product type paired in the whole system.
