"(I measure the oval opening at 1.5" x 2-3/8") "
your measuring the hole thru the plastic passthru piece. we remove that plastic piece all togather which leaves us a much larger hole to pass 3" tubing thru.

can/will we make a dual cai for the srt6? already have, waldig has been running it since summer. we are still waiting for a sample silcone Y section for the TB to properly do this as the prototype coupler was a cut and glue'd deal (not pretty enough to sell). was their gains to the setup? sure, IIRC it was a 12hp increase at redline and an even greater increase under the curve on the way up.

there will be a very tight fit past the tube into our new intake manifolds but is still do-able

is there a bang for the buck for basically doubling the price of our cai kit? thats the question! so the cai^2 will see the light of day this spring and we'll see if anyone purchases it. we also have a nice tweak (and much cheaper) to the current cai we offer thats being tested now on ours as well as another members ride. good things to come
