I'm trying to decide between the supertrapp ids2 with race core or the supertrapp 4 in. racing system. The ids2 is $330 and the 4 in. is about $310 and both are complete systems (the prices were on their website and i will find cheaper elsewhere but its just to compare them). Anybody know which one has better performance gains?

 

all i have is a white bros so i couldnt help, but just take a look back in these forums and im sure there might be something that would tell you which pipe is good

 

I would go with a White Brothers. Be sure to rejet your carb and you will notice a nice difference in power.

 

i have heard that the supertrapp is the best pipe on the mojave but the white bros is also really good.

 

you dont really ahve to rejet. the onyl problem i have with mine is if a let off the gas in fifth gear and slam it back on it kinda bogs. other than that the mojave jetting is dead on for the wb.

 

I have the IDS2 on my lakota and I am very happy with it. It gave the bike a decent bottom and mid-range gain in hp, not so much in top end though. The IDS2 is also tuneable with the disc that comes with it, so you can tune it more for the type of riding you do (i.e. low, mid, top-end gains). If I was to get a mojave I would buy the IDS2 again. You will also want to get a K&N air filter and also rejet your carb to get the most out of your pipe. With a filter, rejetting, and pipe you would notice about a 15% increase in power throughout the powerband. Goodluck with whatever you get, and let us know how it does[img]i/expressions/face-icon-small-cool.gif[/img]

 

Trust me dude rejetting helps a lot... when my friend got his fmf pipe on his 300ex... it didnt make much of a difference then when he put a bigger jet in it dude that thing made a pretty big difference...
peace
