This summer I've decided to change the stock exhaust and to remove the cat with some louder stuff...
I've decided to use the GPR Deeptone (racing version, without db killer) and it looks awesome! It is lighter and the sound is...oh bro! The sound is AMAZING! However, I didn't remap it, but I think I should do it. I've done the suggested things about 15mins idle and etc, but I'm talking about a real ECU adjustment and remap.
And that's the reason to ask you - are you aware of some existing ways to do it or do you have some info on the matter that you can share? I'll be more than happy to hear your experience/thoughts on that!
P.S. In the attached file you can check how it looks like with it.
