does exhaust make you run richer??
ok searched and didn't find anything realy pertanant, when you upgrade your exhaust do you runn richer than stock or leaner? i am pretty sure on a piston engine you runn leaner but a rotarty is seldom like a piston engine. going to get my cat back done soon and don't want to run to lean since my timing's advanced...
any help would be appreciated james |
Leaner - same as a piston engine.  The engine is still an air pump.  The more efficient you make the engine and free up flow, the faster it'll ingest air.

the cat back alone won't make much difference. it also won't add much power though.
