MAC header concerns
Okay well I just got my new gt40 P heads and from my understanding from calling and emailing companies, the only long tube that will work on the P heads. But is it just my imagination, or is there alot of MAC bashing in here, and I am wondering and nervous to get these, but I already have the long tube h-pipe, and I would rather not replace both the headers and the h-pipe.Could you tell me why they are bad, and what the concerns are when stating they are "crap". Thank you.
