TVS yes, but the Whipples are fairly cheap. They can be had for $22-2500. I would part with my whipple for $2500 and had a guy lined up but I backed out. I'm going to wait until VMP figures out if they're going to release an EGR equipped TVS before I sell mine. 2.2's sound cool but they're really just billet grenades. Not something I want sitting above my motor.
I'd probably part with mine for $2500 as well, but at the time the KB 2.2 was available for a good price so i went with that. I wouldn't go as far as being a billet grenade, but if you do enough WOT pulls VMP, Whipple, and KB will all get heat soaked unless your running a KC to help minimize that.
