Although I really like the sound and performance of my Arrow 4-1 & Staintune.... I’ve always disliked having a side of the bike with no muffler.

Add in the sound of the 4 cyls each puffing independently and the lure has me dreaming, watching YouTube videos etc every few months of all the 4-4 videos I find.

Personally I like the look of the Moriwaki the best by far. They are the most well fit to the frame and lines, and the quality and welds are unmatched.

That being said- I went with the Pipemasters today for several reasons.

#1- the Moriwaki have small cats in each pipe. For most people that doesn’t matter- and in fact might give a more reserved quality sound without any harshness. But it also may choke off a couple hp and if I can avoid that- well, I will.

#2- centerstand. Yes I need to buy a dlx centerstand but I’m ok with that and would rather have it than not. This is probably a bigger reason that I didn’t go with the Moriwaki than number 1.

#3 - O2 sensors- the Moriwaki like all the others is sized for the stock Honda sensor- but I reached out to Pipemaster and he said not a problem- he put normal sized O2 bungs in. I also contacted Dynojet and they made
me a custom file so I can run the autotune on our bikes with 2 sensors. I need to buy a new autotune kit that is made for the 2 sensors, but it will work now on our ‘dlx’ bikes. I don’t expect much difference- I just like to play. I’m sure the bike would run fine on the same single sensor file I already have.


So yea... not my first choice if Moriwaki had a center stand, no cat option... even if I had to have the bungs welded on myself... but given those things.. I’ll deal with a bit of homemade aftermarket look / fit.
