Got one on my XR6T it is f*cking fantastic. Much more punchy off of the line and you can feel boost come on instantly when kickdown from cruising, it's induction roar is louder than the stock exhaust and the flutter on throttle off sounds loud enough to have pedestrians snapping their necks to see what the sound is coming from. Buy from ebay if you get one as I saved myself $240 got it on bidding for $360 reg price $599 most satisfying mod I've ever done. when I first drove it couldn't wipe smile off of my face. And first time it fluttered on throttle close I Just giggled to myself like a little schoolgirl. Took me from 200.5 rwkw to 217.3 rwkw when fitted with a powerstat theremostat at same time Also was informed that will not tune into full power for another 500kms so I'm waiting to re dyno the Car for the run in rwkw. Also gave me significant torque increases pre and post spool up. Fuel consumption is also lower than standard when I'm holding speed, overall can't tell you as I spend too much time on boost.
