Thanks Stinger GT SS, totally agree with your thoughts on the Varex x force system having also heard it "live" The EVC feature is really handy. Got to be honest not a fan of the Kia bi modial exhaust and haven't heard too many rave reviews but each to there own. I have test driven an example and it was hit or miss. My Ark grip with the addition of me Sound deadening the whole trunk has helped with the drone. I believe you can get the axle back Kia Bi modial exhaust for around $2600 fitted by Kia. My Ark grip non EVC fitted $2800. $AUD.
