Interested to know what causes the large amount of exhaust crackle on these engines. I usually like it on other cars, every coyote ive heard including mine sounds so poppy and tinny on deceleration its just not a nice sound. One or two crackles is nice, but coyotes seem to do a couple a second. Mines just a cat back but ive heard cars with full systems the same. Also on my standard tune it does it alot less. Would be interested to know. Cheers
