K&N Stub Stack

[Pbum5]

Just wondering if anyone uses/likes a K&N Stub Stack?

Does it help at all?

Thanks

I don't have one of those, but I did cut off the air horn on an old Holley to see what it would do. Yes, there is a difference!

Tried it

Tried it on my Edl. Didn't clear the carb linkage correctly so I had to carve out a bit more of the plastic. Didn;t get it onto a dyno.
