I've been reading lots of threads on different MMs for the first gen V and I am leaning towards doing the Revshifts. I have the car torn apart and waiting for a header install right now and decided I should do them now while ive got the exhaust/cats out of the way. Anyone have any issues with header heat on the Revshifts? I read reviews after a few hundred miles - just wondered how they were working after 10k miles or so? Any need for the silicone heat jackets?
Can they be installed with headers in place? Kind of forgot to order them and wanted to put the car back together today so I can hear the exhaust...will i kick myself later for not doing this all at the same time?
