Just threw mine in last night. Love it so far, the sound is great and if you drive it in a relaxed (but not QUITE granny) style, you don't even hear the difference which I like. Only hear it when you want the teeny little bit of oomph it gives.
Gonna keep an eye on the clamps and such, tighten as needed.
Also, picked up every part needed at MOPAC in Langley, spent about $100 overall.
Easy to install and easy to notice the gains. Then again, anything on 109hp is a gain
Props to SID
