2012 Apex SE Mod question

[Extreem]

Hello,

I have a 2012 Apex SE with Ulmers Clutch Kit and studs. I am thinking of doing Elmer's PCV and Airbox mod, along with the 23 tooth top gear. Does anyone know what I can expect from these mods ? Also, what about the exhaust ? Are there any real gains to be had with going with either a Bender or Hauck can or should I leave it alone ?

Any thoughts appreciated.

I have a '13 Apex XTX, regarding the exhaust, I just sent mine to Schimdt Bros. Racing and they "gutted" it. I just fired it up today, and like they told me, there is barely a noticeable change in volume at idle to engagement. I didn't want anything loud or annoying. "Supposed" to gain 3-5 hp and save 3 lbs to boot.
