What would be the gains of one vs. the other? How good is the factory header? It seems HMF and FMF are the only two that make headers, anyone else?

On most street bikes, the difference between slip-ons and full systems is around 7-9 hp, not including the rediculous claims that some pipe makers say. So on a quad, single cylinder and mostly a straight running pipe, I would say around 3-5 hp gain. These numbers are only based on my experiences with many years of street bike modifying and stuff. The problem I have found is that the FMF header will only work with thier cans, due to collector sizing.

I read your threads about that. But I also read that the FMF muffler will fit on the stock header. Wouldn't they have to be the same size?

The FMF Muffler comes with a bushing to use with the stock header, The FMF is 1 1/2"

Awe c'mon it's *only* $250 more than a slip on . (eBay)

Of course then you have to get a fuel injection programmer.
So $750 later... 2 weeks after I spent 8000 on a new quad.. :nuts:

I thought about the titanium but didn't see the extra dough being worth what you get. How loud is it compared to the others or you can get any style in titanium?

I just got my HMF Ballance QRS (slip on only), along with the HMF/Dobeck optimizer and a Velocity filter. It's been cold as hell since last weekend, so I haven't had a chance to get them on yet.
