This thread is discussing single turbo exhaust...i have berk street exhaust and on my taste, idle is a little bit too rough (GC turbos for sure flow more free than stockers on exhaust side so they too let more noise pass to exhaust than stockers) but on cruising speed, it sound nice, deep enough but not irritating loud and if accidently happend that i been challenged for a race, on full boost WOT, who fuck cares..
Work of art! too bad is under the car. How hard is it to do a DCT swap? I was thinking go that route or manual once my transmission gives out (crazy thing had zero issues at 25psi). I miss having a manual transmission.
VRSF exhaust heard is a great exhaust. Just how I like it the sound quite all the time except when you are on it deep sound. Might be my next buy.
Might not "count" since it's an N55, but they are single turbo, so... Hands down the best I've ever heard is this car.
