I buy this exhaust because i love VQ engine sound with HKS exhaust . If you have like me G37S with rear steering you need to modify because this exhaust is not compatible for HKS with rear steering, i know that before i buy but i don't see that here .

I have a 2008 Infiniti g37s coupe six speed manual transmission rwd I am very satisfied with concept z performance I will not order no place else for performance parts customer service is always there to help with any questions that have and they will answer in a very timely manner I am recommending all my friends to buy there parts from them
