Esr pipe problem, what do I have?

[Usmoneylover]

One pipe is badged TRX-6 one is TRX-5 ...look the same to me.  Does anyone have any measurements or know how much different the pipes should be?

I am assuming the bottom pipe is the TRX 6. I can see 3 cone sections after your center section of the expansion chamber. It also looks a little fatter than the top. Also the overall length of the expansion chamber is longer than the top pipe which means it should produce more low end power.
