@twister - yes, intake and exhaust are installed. Butt dyno senses more power! Not sure if I need the JB4 as I am satisfied with the current gains. I've also installed 20mm spaces all around and Eibach Pro springs.Hey Ronrock, did you get your exhaust and intake fitted? Whats it like, performance gains? I am an Infiniti Q60RS owner with full stainless from Fast Intentions and intake kit running JB4 for extra boost but I'm looking to get away from the brand as they don't care about their customers? I love the G70 but wondered if I can get to a comparable performance level.
