Update: went to the local track (1/8 mile) I went from a 8.525 to 8.361 in the 1/8 mile Kooks only with stock cat back (75 deg. with high humidity) And got the official Kooks CEL, I feel so special :crying: Would not trade them, AAWWW YYYAAAA
Unofficially converting to 1/4 mile times ( x 1.57), it's like going from 13.38 to 13.13, a solid gain of -0.25. On a good day at a 1/4 mile track, we could have a new member of the 12's Club. Congrats! Claude
