Are you running the long or short filter? Just curious how far the long one hangs down compared to the suspension components. I don't want it susceptible to damage from road debris or anything. It's weird the long filter is like $15 cheaper than the short one?

 

I don't have the SPE Kit, but I did the MDDP Cat Conversion with the big 1R-1807 CAT filter on my 2017 F450 P/U. It does not hang low. I have had no issues with the system.

 

Awesome thanks! I would rather run that one for the extra capacity and the fact that's it's so much cheaper.

 

From the pictures I have seen the 1R8017 should be above the front axle (assuming 4WD), which should protect it from any debris.

The specs on the Cat filters aren't radically better then the OEM and the loss of the bypass keeps me away but Cat filters and batteries are surprisingly economical and the build quality is always really impressive.

 

I got the shorter one. Filter is still giant. Couldn’t imagine needing a bigger one.
