I was going to post up a similar question soon so this thread has good timing.
I am the very proud owner of a new MY17 Nismo. The car is great (incredible) but the exhaust leaves a little to be desired, especially coming from my '09 370 with ARK Grip system.
This weekend I installed the ART Test Pipes and sound is improving. The car only covered around 230 miles, so would I be right in saying that once the current Nismo system has had chance to bed in it will sound better?
I don't really want to remove the Nismo system as it all adds to the charm of the car. But I could do with some more noise. So I had thought about getting a different Y pipe, but leaving the Nismo muffler on? Anyone achieved similar?
