Pretty much the only way to tell if you have a rev limiter for sure is to put a tach on it. If won't rev up to over 7-8k rpms then you probably have a CDI with a limiter in it.
The exhausts are expensive because a) they cost us dealers a small fortune to get (we make VERY little profit on them), and b) the exhaust wholesalers don't have them made in large quantities so they don't get the volume manufacturing discounts. The marketplace just isn't big enough for it.
These are custom fit pipes for the buggies, since the header pipes for scooters won't (usually) work because of the (poor) design of the buggy engine compartments. If we could use the scooter exhaust headers the exhausts would probably be at least $100 less.
