    Quick and as advertised

    Ordered up a set of exhaust studs and gasket, shipped quick and was packaged perfectly. Parts were excellent and were in stock when others had 2+ weeks lead time. I had a question so I emailed them, had a response before the end of the day. If they had more rb25 parts I would have ordered everything there. Prices aren’t the cheapest, but they are fair and the speedy service makes up for it. I will be a repeat customer.
