This is my custom dual intake, I made this setup nearly 6 months ago but never finshed it until last week i used 2 silcone 90's cut to make a merge collector with Woody's advise months ago but ended up switching to the hard pipe merge collector later hoping to increase the velocity of the air into the throttlebody. The cool tape works wonders at the track. It doesn't prevent heat soak on the pipes but it takes extremely long for the pipes to get heat soaked and even when they do you can touch and it wont burn your hand. Where before i put the tape on it would be hot enough to burn your hands.

Haven't tested if there is any improvement at the track because its rained non-spot here on track days. I can hear more whine earlier in the rpms and a slight increase in whine across the rpm range. With the old silcone couplers i could blow in one side and feel nearly no air come out the single side, but the the hard pipe i could blow into one side and feel all the air come out the single side.

New collector vs old merge collector
