Has anyone had a problem of the cyl #4 primary hitting the coolent tube behinde the engine? i had to hammer the tube flatter so it would fit.

 

mine did the same thing... also did the same thing lol... didnt take to much

 

mine seems fine

 

ahh, that sucks man, shouldnt make a diff but id keep an eye on your coolant temps for a lil while just in case

 

I've heard of this issue before, but I was thinking V2 was supposed to fix it?

 

idk but i do notice a differace above 4000 rpms in power i like it.

 

i had my v2 on, then changed it for a zzp midlength, havnt dynoed either, but i feel the v2 was a little better.. im thinking of putting it back on

and i think the clearance problem was only on a certain year, 2006 might be a problem

 

i have an 06 with the v2 and no problems at all
