Hi, I'm Bob Holcomb from Apex Automotive in Great Barrington, Massachusetts. The question today is, "Can I replace my spark arrestor or my resonator with a piece of pipe?" I guess the quick answer would be yes. Although, the spark arrestor or resonator is place in your exhaust stream for a reason, the manufacturer of the vehicle uses this device to muffle sound and also create proper back brusher for your engine to run most efficiently. If you remove the resonator or spark arrestor and put in just a piece of pipe, it could change the back brusher in your exhaust system and your car may not be as efficient. This is a different type of resonator. It has something called a baffle changer. When your engine is running, the gases don't come out of the exhaust stream smooth, they come out in pulses. This device absorbs the pulses and it lets them come out the back side a lot smoother and quieter. It also builds the proper back brusher. The back brusher is important so that the exhaust gases come out of your combustion chamber at the proper rate for the best fuel efficiency and peak performance of your automobile. So, yes, you can change your resonator with just a piece of pipe, but it's not suggested. I'm Bob Holcomb from Apex Automotive in Great Barrington, Massachusetts.
