Hey guys, im looking for a set of USED/NEW nismo exhaust system S tune(or nismo stock) or nismo mufflers.there is a chance i might able to get my hands on the Y pipes and the mid pipe from my local listing. if you guys have just the nismo muffler for sale, let me know. otherwise, i will buy your cat-back system. i believe only the 350Z nismo exhaust will fit my 03 G Coupe with 6" extension.
