Mac 4:1 exhaust

[jcasey007]

bit of an update - My Mac 4:1 exhaust arrived and I was able to fit it today, WOW what a difference it makes!

apart from it being a bit quieter than my home grown 4:1, starting is easier (like first button push from cold) she revs better and is more responsive.

so I guess these old Honda's need a bit of back pressure to operate best!. The home grown system was a set of 4:1 headers with a cherry bomb welded on the back.

well please
