Hey guys I’m wanting to pick up a slip on FMF Factory 4.1 for my ‘18 YZ250F. Is there any performance differences between the Titanium and the Aluminum one? I’m thinking weight and color is the only difference really. Just curious what everybody else runs and how well you liked it. Eventually I’d like to get the stainless megabomb header. I’ve heard that the titanium and carbon fiber isn’t very durable?

It does look better but it’s also over $100 then the aluminum one too

I ran the aluminum with the carbon end cap on my 14 450. I think the blue ano is too much blue on the Yamaha's. Just my opinion. I liked the aluminum look better. As far as I know, no difference other than weight.

Good call. Could be a bit much with the blue rims too

I can definitely see that being too much.

Mine is one of the first batch 4.1 for the CRF. Has 30 ish hours on it and looks great. I did replace the decal this summer. CF holding up great and so is the blue. Durability is pretty good on these ti systems. I have the stainless header and it doesn’t look as nice.
