Do not buy anything from that craapy company! I have their H-Pipe and the cat went bad after 4 months. They said to ship it back and they shipped me another one. Now they are saying I will not get a full refund since the cat is not messed up. I had a shop look at it and it was confirmed that their product was damaged. Then they give me the runaround and bullshti answers. Why the hell would I exchange my brand new h-pipe for another brand new one of the same kind? They can't seem to answer that question. Also, they claim the product is not sellable anymore even though they first claimed that it is perfectly fine. I had to pay installation twice for this piece of garbage. Okay....you probably couldn't understand all my complaining because it is all thrown together........but basically, MRT is garbage and their customer service is ****y too and everyone who picks up the phone there claims to be a fkn manager.
