Had one on my GTT and was good didnt realise it was full system. any pics/sound clips
Don't take this the wrong way mate, but I don't think you will hardly gain any kind of power out of a IS200 unless you turbo or supercharge it. If I was you, I'd spend it on the springs, front lip (just under £150 inc Vat from Lexus), rear lip, HIDs and maybe light tints. Side skirts are also an option?
BTW, anyone know where top pick up a rear lip from (apart from Lexus)?
I have decided not to bother on engine mods just yet. Getting set or TTE springs and possibly Eibach ARB kit
