You will notice the difference. I also have the 7 port that I put a 086 dynamite on. but after it's broke in I am going to try the jp-4 on it. the jp4 was suppose to make better bottom without sacrificing mid-high. worked like that on my 28rr axial,perfect match. I went with the dynamite brand because of the price(49.99) maybe less if you can find a used one, good luck.
None of the JP pipes work particularly well on the GO motors. Some are just flat and others don't offer the economy you should be getting from the motors.
Go with the Dynamite 053 on the 7 Port if you want to stick with Dynamite pipes (they are exceptional value for money). Best performance on the 7 is the 2047 pipe with long 0801 header IMO.

7 Port you need a pretty late clutch to get some revs up and clear the motor, otherwise you may bog a bit out of corners etc.
I find the VP Pro alloy or XRay 1.71 alloy shoes with 1.1 springs ideal on the 7.
5 Port I run the same set up, but if you want to tame it down a little go to 1.0 springs. People will disagree with these set ups, as their track surfaces and lay outs will be different. We have a lot of jumps straight out of corners and the tracks are fairly tight, so this works for me. I have never used carbon shoes for racing. Alloy gives better bite and they last much longer.
