Disc's or endcap on WB e-series?

[BoMbEr416]

I have a E-series Pro-meg full exaust on my 400. it has the endcap on it instead of discs. my question is would putting on all the disks give it more power? or is the endcap still the way to go.
i have 10 disc's plus the spark arrester disc and the endcap disc. what would give me more power?

ok first off you say u have the end cap. is it the turndown end cap, (kinda like a 2 stroke)?, or is it just wide open with the eliptical end cap (stock) with out the disks and spark arrester plate???? we need some more info. cuz there are alota end caps. the disks will give you more fine tuning ablility than just an end cap. your best bet would be to try both setups and see which result you desire the most.

I run 12 disks and the spark arrester.

The more disk you run the more it opens it up. = better top end. Less disk = better bottom end and quieter. Adding more disk may help your 416. Try 16 and see if you like it.

I run 18 discs on my 426 and it does really well.

i runn 12 for better bottom end, and im too lazy to go buy a larger main jet to run more
