Stagea Exhaust

Have a Stagea 350 RX '05  normally aspirated. Has speed limiter on it. If i put a speed limit blocker on it does it affect mixtures at 180km/ph onwards?

We have no emissions test here so if i remove the cat (keeping O2 sensor) will it affect the performance in a negative way or just make it smoother and noisier?

cheers

Most of the advice is not to remove the cat due to the overwhelming smell of fuel afterwards.

Cheers mate thanks for advice.

Had an HKS speed limit defeat thing on my first S1 - don't know how it works but don't think it has any effect on AFRs.
