HSV VX XU6 Mods?

[Influx69]

hi everyone, i have a hsv vx xu6 and am planning on doing a bit of work to it as i havent really done anything other than change the pulley to 10.5psi and 1:9 ratio rockers and custom mace engineering pod box but am wondering if k&n make the typhoon filter to suite holdens? i heard this vs supercharged v6 yesterday and the whine was extremely loud, im just wondering what mods you can get to make the whine much louder? and what is the greddy cooler like on l67's?

There is so much that can be done to these little monster motors.
Do a search on the various forums but the best forum these supercharged V6's is: L67torque.com
!0 si pulley and 1.9 rockers are a good place to start.
Don't mess with the exhaust at this stage as the XU6 exhaust won't become a restriction until you start intercooling and going for big boost.
