Thanks Akorenika. I was actually after an OEM set of Arrow pipes and that's what I purchased. However when I opened the box I saw these and I thought that perhaps the seller didn't know that this was a set of RG3? I was thinking I had the deal of my life haha English is not my first language either that's probably why I didn't spotted at first that it sounds a bit broken.That looks positively hand stamped by someone who's first language isn't English. I would also question that it's stamped on the one part that's easiest to replace.
I bought them very cheap but if they are not an original RG3 I will return them. I already have a modded exhaust but prefer OEM or genuine RG3s.
