I tried to order a N1 universal exhaust from them. I wasn't sure if the order went through or not. I try emailing them a few times, and they never got back to me. I ordered from them because they're located in Houston; relatively close to me, so it would get to me quicker. Anyway, if the order didn't go through, maybe my cc was declined, or whatever; they should at least notify me. I should have guess what kind of service I would get from a shop that deals mainly with the H and A. DOH! Last time I try to order from them that's for sure.
