Frequently Asked Questions
Should I replace the water pump while I am in there?
Yes - it sits in the same area, so doing it now costs only the part, not a second teardown.
What is the most important step?
Setting the cam and crank timing marks and confirming them by hand before startup - get that right and the rest is bolt-on.
Can one person do this kit?
Yes, but a helper speeds the awkward parts; the real requirement is patience and keeping the fasteners organized.

I'm very happy with the exhaust. It sounds great. I was juggling between this one and Special K's behind the bumper exhaust and I ultimately decided on this one. Installation was easy and the only thing I would recommend is getting some washers because the holes on the flange for the growler are ovaled out to allow for adjusting the fitment. Without the washers the flange nuts were just a bit to small.
I buy almost all of my Honda Acty product through OIWA's website and have never had a complaint. I would highly recommend OIWA's website for any kei truck products.
