I have been thinking about a Moriwaki 4 into 4 exhaust for my 2017EX, but have some questions maybe some of you guys out there that have it can answer.

1.) I am a little reluctant to give up my center stand, so for those that have the M4/4, has it been an issue, and do you miss the center stand?

2.) Generally an exhaust change requires a re-tune. I dont want an add on like a power commander, so is it necessary to re-tune , and what procedures have others used if it is necessary?

3.) Does the M4/4 have oxygen sensor bungs? Should it be used with sensors, or without with bung plugs?

4.) The M4/4 is stainless single wall pipe if I am not mistaken, whereas the stock EX is chrome exhaust is pipe in pipe that eliminates pipe discoloration. Has anyone found the M4/4 stainless to discolor to any significant extent?

My thanks to anyone for answering these questions for me. http://cb1100forum.com/forum/images/smilies/clap.gif

The Moriwaki is my favorite 4-4. I love the look, just not the price. I would consider giving up the center stand for it, and it alone.

I'd advise a fuel adjust for anything other than a slip on muffler based on the dyno runs I've done.

Even with a simple muffler swap, although my Staintune ran beautifully seat of the pants, adjusting the fuel would have probably made more power and ran cooler.
