<div>Thanks for everybody's input. I have a couple of super trapps. Never really cared for them on my hillclimb car. They create noticeable back pressure with plates and end cap. I hole sawed a 1-1/2" hole in the cap which allowed the motor to spin a whole lot better but was a whole lot louder too. I have a spiral muffler from another project but it is 3-1/2" inlet/outlet. Maybe I'll pick up a 2" inlet/outlet and try it.</div><div>Thanks again.</div><div><br></div>
