[Speed Limiter 2009 Impreza STI GRF]

Hi All, 

 

Happy new years to everyone! Hope ya'll are afe out there. 

I think there is a speed limiter at 190km/hr. Not that I need to get it removed but just curious if it can be done? Have any of you got this done?

Nah hasn't been for me with either car. Jap ones don't seem to use the o2 sensor to check for cat efficiency the way US one's do. 

Thanks Andy, yup. I'm all good, did not make any difference to sound though but response has improved alot. I'm happy though. 

 

Next on list is muffler delete..... Thanks all

Will the O2 sensor be a prob? 

Will engine light switch on?

Ahh sweet, thanks all for the reply! I will give it a shot and let you all know what the results are. 

 

I have taken a measurement of Noise level(decibels) so will post a before and after just incase if any future soooby wants to take a shot on this.

Hey All

 

Just needed some advice. 

I'm looking at hollowing catalytic converter. Is this recommended? 

Want to get more rumble out of it. Would this pass WOF?
