The only way to really know what will work is to test it out your motor with different pipes. What type of vehicle do u run, and what motor and pipe combination that will give me a better idea of what you are trying to compare, and what size tracks? Pipes that are designed for low-end will give low-end punch, and not as much top-end. Pipes for top-end will have a little less punch but more top end. The motor respnds to the backpressure of the pipe if i am correct and this is why the pipe is important. With a motor with a lot of top end, you can put a low end pipe on it and it will give it more low-end. Same goes for putting the top-end pipe on, but you will give up the low-end punch. Hope this helps explain it.
