The MAC allows filter access for sure - I have two of those for the big KZ's and one for my CBX's. The problem with the MAC is the silencer. It is very restrictive / small volume / reverse flow and will cost you top - end power. These silencers are too restrictive even for a 650, and are heavy and not that quiet, either. Mine added at least half a second to my stock GPz1100's 1/4 mile ET. The back pressure would gradually push the silencer off the collector on the GPz at the track no matter how tight I torqued the clamp. Even with the 6-2 (two silencers of exactly the same design) on the MAC for my then stock 1047 cc CBX, the bike wasn't able to exhale at high rpm, The MAC headers are good enough, though. I would use a shorty generic 3 or 4" stainless Supertrapp silencer on the MAC header, which is what I'm going to try next.
I also have a new Delkevic, I just got it and haven't tried it out yet, so I can't say for sure if you can get to the filter and drain plug with it. It comes in many sections and is held together / on with the classic spring and hook system found on most road race replica systems. The head pipes look like a copy of the MAC design, but are not welded together. I have looked at the silencer and it seems much better than the MAC design.
The Kerker is supposedly the best for performance; I bought one of those, too. It is also still in it's shipping box. I'm pretty sure it doesn't allow filter access, however.

Forget the Marving if you want access to the filter and you can "just" get to the drian plug -( Z1R) but I have to say that I don't mind removing the pipe every second service, at least I can clean it properly and it only takes about 15 minutes to remove. The exhaust gaskets usually last at least two removals if not over tightened. This pipe is the best I have tried and that includes Tingate ( racing only), Yoshi (very loud, good but annoying), Peter Allen (second best), Delkevic (agree with the jigsaw bit), Marshall? (great sound but still no filter access) and others, I have not tried V&H or Kerker because from what I have read they can be very loud (I'm getting old)Kray-Z wrote: If you want cheap and durable, get a ceramic coated MAC. If you want cheap and good, get a V&H street - I've heard good things about them. Too bad they only come in bright chrome. If you want a 10 000 piece jigsaw puzzle, try the Delkevic. They even throw in a hat and T-shirt in the box. The Marving pipes from Europe (I believe the Netherlands) might be worth looking into. They look great and from reviews I've seen, sound awesome. More money, though, and you will have to check about filter and drain access.

I could swear that I read on here recently that there were two different Kerker designs, street and race and that the street version does in fact allow filter access. Wish I could find the thread.... :dry:Kray-Z wrote: If you want cheap and durable, get a ceramic coated MAC. If you want cheap and good, get a V&H street - I've heard good things about them.
