Also got the EuroTune last year during the $200 special. Get some 3" 'T' clamps, the screw clamps look cheap.
the single is sufficient for most na owners, the dcai has less restriction so there is power/efficiency gains there, just not twice as much as the single.
as for using t-bolt clamps. if someone wanted them instead we could ship the kit with those but i prefer the worm gears as they will not allow you to squish/damage the alumium tubing under the couplers. we use a very nice stainless worm gear clamp, not the old school crap ones that strip out the first time you try to tighten them.
