Ha ha!  Sorry that's what I meant!   

  But any of those combinations will bolt right up?  What about connecting to the frame near the muffler?

They all interface with the engine ports in the same way.
There are variations in how/where they attach to the frame, and interference with center stand kick start lever, brake lever, and foot peg.

If you want all new, probably the cheapest is the MAC system 4 into 1.

Best fit would be stock 4 into 4 if you can find all the brackets and fittings to do so.  Probably most expensive, too.

Then there is new old stock, if you can find them.  And, of course the used and salvage marketplaces.  Prices vary.

Depends on what your goals are...

Cheers,

  Thanks for the link and the advice!

  I assume changing the exhaust will require retuning the carbs to correct for different pressures?

Ben,

Loudfastugly.com has original MCSC 4-into-1 exhausts for $219, gorgeous chrome.  (I got one for Christmas.)

Incidentally, I got that umbilical for the fairing.  Thanks so much, man.

Depends on how well you insist the bike run and how different the back pressure curve profile is from what the carbs are presently tuned to.

The SOHC 750's are pretty flexible compared to other bikes, particularly those with CV carbs. I'm running my K3 with stock airbox and 4 into 4 pipes with the original (for Oz)105 main jets, and my K1 with straight out drag pipes and pod filters, with 110 mains, which are probably a little lean you'd think, but it runs well, starts easy and accellerates away from the lights fine. (But makes one hell of a racket!)

On the other hand, my Suzuki GS1000S with CV carbs won't run properly with just an aftermarket 4 into 1 pipe and a foam filter! Best rule of thumb is the "seat of the pants" method, rather than going into all the "what ifs", just take it for a ride, and do a plug chop. (Buffo's favourite diagnostic tool) Remember, if it feels right, it probably is! Cheers, Terry.
