Other than the need of a BOV,I think it makes the car sound sick!

 

I love how BMW said this car ONLY has 300hp. Well it turns out that this car has almost that much to the wheels. Also, with a procede chip, downpipes, cat-back, and good intake these things can be in the 375-400RWHP range on stock turbos. There is a company called Technik who built a wide body 335coupe with 305's in the back and an LSD. With 400RWHP this thing will be a beast. I think that the N54B30, the engine in the 335, will be the next Audi 2.7T, possibly even the next 2JZ. It is only a short time before we see large single turbo 335's with 600+HP.
