It has been a long time since I last visiting the forum
Have done some upgrades since last, but not really big ones.
A stubby antenna, K&N intake filter, M shortshift gearknob and rear decat with straight pipes from Milltek.
After mounting the Milltek I could not only hear but also feel the difference. Using ESS flash and with the exhaust upgrade I felt more power on the top revs.
The sound is awesome also, with popping sound all the time, especially when I shift gears . I think the sound got around 20% louder as well. There is also a 35is exhaust system mounted on my Z
