I have a 2003 Z-400, I want to know who make the best pipe, and what pipe to buy to get the best gains. I am looking mainly for HP.

My wife has a z400 and I've been leaning towards HMF for it. Seems like alot of people are happy with HMF, plus I think they look cool cause they come in different colors. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

My bro has tried two pipes HMF and LRD. No difference. I have a HMF slip on for the wives Z. Good gains, but not as good as a full pipe.. Get some cams first and take the peashooter out. When more money comes then get the pipe and filter..

Both cams or just the intake? I know some people only change one.

My bro did both. You will lose bottem end, but mid and top are very nice.. The cams w/ installation are about the same cost as a pipe. The peashooter removal will let it breathe w/ lid and snorkel off w/ a rejet and it's all free..

I am of the opinion that the pipe matters little. Hell peashooter outis close to a slip on. Get the one you like, the one your dealer likes, or whatever floats your boat. Spend some time dialing it inand you are ok.
I hav also pu ton the cams(both), and rthe DRZ basee gasket, which raises the compression a point, the cams drop compression a little, thanks to the duration, so I am still on pump, until the really hot months. I have a FCR carb as wel, and I feel like the bottom end was not sacrificed at all in my set up, But I did raise comrpession and have a bigger carb.
If any of you guys run your Z in the sand and are not worried about losing an air box, let me know, Ihave a really nice intake set up, that dithces the box, and uses a 400ex size filter. Much better flow!
