Only 98. Never tried race fuel, but it is possible to buy here 102, 106 even 116. Price is approx USD 4 per ltr.
Regarding pipes. I`am using standard exhaust, without cats and slightly improved muffler
(don`t like noise).
Intake pipes - not so important, you can take FMIC and make assembling with required pipes, the same dia as new cooler intake.
