I am new here and this is my very first post. I have been looking around on here for a couple weeks though. I had found some info about a week ago on the HMF exhaust but I can't find it again for some reason. I just got an 04 Busa and put on the HMF high mount slip-on. I was wondering if there is a good MAP for this exhaust or something that would work until I can get it in and have a custom MAP done.
