HKS "2Stage Exhaust System" 45th Anniversary Limited model
 

Available starting in April 2018, JPY 320,000 for those of you interested. Only 20 sets worldwide.

Similar to Fujitsubo Authorize-V except this is dual tip.

Loving that ability to have best of both worlds. Both aural pleasure of engine reving, and ability to quieten it down when cruising or to not anger cops/neighbors.

Only 20 sets, so they're already gone by now :)

At what is $2000-2500 I would imagine probably not....

I found out today that Fujitsubo is updating their Authorize-V.
The current version is GPS based and activates the valve at over 30kmph.

The new one will just have a user controlled switch that you can turn on/off. It will be cheaper.

I think MSRP will be somewhere around $1300-1400 if I am understanding it correctly. If so, it'll be a much better option for street exhaust users.
