Yep gotta get tti s

so how much higher do the dougs sit? a measurement would be nice.. facts like that would be very helpful to a lot of guys here.. like i said, i never heard that one before. not saying its wrong. just i never heard it before.

not sure what issues you are talking about with the tti. but like i said mine went right in.. didn't have to ding them anywhere.

I will see if I can ask a friend for measurements from k fram to floor then lowest part of collector to floor. But I believe I was told on here it was around an inch or more
