Just the pipe is different. Probably not wise to drill a hole in a spec exhaust.

But just grab a 3 pipe and throw it on and you should be fine. You can run a bit more RPM with the 3 pipe compared to the 2.

TJ,

Thanks for the reply, it is extremely hard to find any info on these things by doing a google search. Just doesn’t seem to be that much info out there. So just to be clear:

Pipe: switch from kpv2 to KPV3
Header: keep same
Carb: keep same and no adjustments
Timing: keep the same

Trying to find a used one, eBay doesn’t seem to have any and the classifieds on this forum have crawled to a snails pace since the forum change.

Yup, sounds right to me. Maybe some engine builders like to build an engine a little differently for the 3 pipe, can’t remember, but you can throw the 3 pipe on there with no issues. Carb settings are the same, around 2 – 2 1/4 on the low and 1/8 to 1/4 on the high. Not sure how you have your carb setup now, but usually we’d start the low at 1 1/2 on the grid to get rolling and once we started getting up to speed we’d open to 2 or 2 1/4.

Header is the same.

Classified section is a bit empty at the moment. Check your local shop or with other guys at the track who run the class. I’m sure at least one of them has a collection of used 3 pipes laying around.
