stage one or two arlen ness big sucker? I feel like stage 1 should be enough..

 

I originally wanted a stage I but the dealer goofed and ordered me a stage II. I actually prefer the size of it now to the stage I big sucker. I ordered a plain cover and sent mine to Venom Imaging to have a custom graphic added. I do use the rain sock and just leave it on. I've been caught in the rain with the sock and have no issues.

My only performance upgrades are 2 1/2 " slip ons with the stage I map/download and of course the big sucker.
