My choices are:
- MAC midlengths (1 5/8" primaries) w/Jet Hot Sterling coating (lifetime warranty) and keep my current Random Tech cat; $618 shipped
- Arizona Speed & Marine mid lengths (1 3/4" primaries) HTC coating + new cat; ~$725 + $225
- 1 3/4" long tubes w/ceramic coating
I'm leaning towards the MACs although I prefer the AS&M, but I can't justify the cost. I'm shying away from long tubes because of clearance issues and custom y-pipe to keep the cat.
Opinions (assuming that I will somehow pay for ported heads/cam)? I've read a LOT on mids vs. long and I think either would support my needs.
Any issues with blocking the head exhaust ports with the smaller diameter?
