Last night I hung out with my friend, he has a G35 Coupe with only an Inejen cold air intake (Injen Exhaust on the way) The car was un-freggin-believable. It handled sooo well. The throttle was responsive the BRAKES! don't even get me started on those brembo's The clutch though was weird, it wasn't as smooth as mine. It had a clicky type of feel to it. It was looooooong too. But I didn't care, at time I was going like around 20mph IN 6th GEAR!!! haha thats soo awesome. All in all though, I'd definetly take a G35 coupe over the 350z, just cause if I want performance, I want luxury as well...and back seats here are some pics of his car
this is what his exhaust will look like in a month
