What would be the best mod to do to my 04 Predator 500 first that is not to costly and has a good gain from it? Any recomendations for an exhaust?

Yoshi or Pro Circuit have a good exhaust(full or slip on) but kinda pricey IMO.FMF is not too bad and cheaper.A good clutch kit is one of the best mods and of course a Uni or K&N air filter and rejet it and a CDI/rev kit.Talk to DirtyDawgDale(a member here)he can set you up with some of this and give you some advice also.

You can go with one that revs 9200 rpm's or higher.Stock is around 8600 (I think) and if you get one too high then yes it is possible to have a rebuild in the near future lol,but the Fuji Predator engine is a good one and they can take some abuse,but too much at 9500-10,000 rpm and it will be done like most factory engines.
