Does any body know the difference in the exhaust for the comp f90 vs non comp f90?

For the comp f90 is the burble because of the exhaust or the tune?

You'll get burble in the base and the comp as long as the engine setting is in Sport+. The sport exhaust is just missing a resonator if I'm not mistaken. Minimal difference.

Burble is related to the engine tune, not the type of exhaust you have. However, the type of exhaust WILL change the tone of said burble.

Standard Exhaust (Base Model)
M Sport Exhaust (First Edition / Competition / Option for Base Model)
M Performance Exhaust (Optional)

My Non-Competition came with the M Sports (Korea) and it pops and bangs in Sports+
