Hi, I have a 200 370z manual. Car has been absolutely fine up until last night was parked up for about 20 minutes, when I went to set off the car wouldn't go past 3500rpm and has a really harsh limiter at that point, is also very judder under 2k rpm as if it was misfiring, also took a few more turns to start when I tried turning it off and back on again. No codes have been thrown. Anyone have any ideas??

After an aftermarket one sorry! Already have the OEM one in the car!

Hi there, I am after a cheap ish exhaust for my 370z, around £350-400, is there anyone with anything?
