I've noticed on here that quite a few people did not require MIL eliminators when they put on a Pro-Chamber or o/r pipe. I haven't really noticed a pattern as to who did or did not need them. Is there such a pattern or is it really a hit or miss thing?
I had to have them right off but what I was wondering about is some people say that they haven't needed them for X days/weeks/months since they put there pipe on.
