I am thinking about having a custom exhaust built for the Zed, its a place in macclesfield called J P Exhausts Ltd, they have just done one for my mates e92 m3 which is on their website, really good bunch of guys, happy to tailor it so its just right for you. He tried a few different versions until he found the noise / volume he wanted. Great quality and good prices too!
I love the Nismo noise but cant afford one so any tips of how the Nismo is put together to try and copy the system?
Cheers in advance
