400ex pipe information

Hey i have an Hmf slip on with a stock header on my 400ex well i found a noleen header for it will my hmf fit on it and everything....

It's highly doubtful. A slip on exhaust is meant to 'slip on' a stock header, hence the name slip on. Usually all aftermarket systems are larger diameter headpipes and more free flowing canisters. Given this information, I would say no...

If you are trying to upgrade to a full system, you are going to have to ditch the HMF slip on and get a full system exhaust.

Are you trying to gain bottom-mid or mid-top end gains? For bottom to mid I would say Yoshimura, HMF, or Fat Boy 4. For mid-top I would say Sparks X-6. Hope this helps....

Or if you are just going for looks, I would look into the LTE Duals....:cool:

Correct me if I'm wrong, but I thought the FMF Powerbomb Header will fit any slip-on (So I heard).
