Hello,
I just wanted to ask you some infos about the new STI exhaust system: i heard that you cannot gain that much of horse power changing the whole exhaust system : that's because of the two lamda sondas placed one at the beginning and one at the end of the exhaust system...
what do you think about it ?
I guess there must be a way to f**k the cats and gain power on a car of that kind...
thanks for your answers and ciao
