I'm going to make a comment on this based on facts.
I know the company that produces in mass quantity the exhaust, the decats and HFCs sold by some of the performance companies that rebrand these types of products.
Some of the other traders on here are aware I have tested some products, decats fitments were ok but not necessarily compatible with other parts, as Wasso/CS found with his Motordyne system.
One thing we also tested and I'm not mentioning any particular company, was that these products were being sold under the description of 304 stainless steel. I got in touch with a metallurgist I know from my old work and had the product tested. Some people will tell you that you can tell the difference between 204 & 304 stainless can be determined by a magnet but this is not the case, the mettalurgist told me the only way you can tell is by looking under a special microscope and looking at the cell structure.
The one we tested, and as mentioned I'm not saying which company it was, happened to be sold as 304 but guess what ? it was actually 204 stainless. It's a cheaper grade of steel that will discolour and fail quicker than 304.
The company that do mass produce these products make the products to order in batches of 20, and you can choose to have them in 204 or 304 stainless, the cost is about £6.50 more on decats etc which confused me as to why anyone would falsely advertise.
A hell of a lot of these HKS type exhausts get sold, they do a LHD and RHD version of this particular one ( I find that bit odd tbh as an exhaust is an exhaust and it shouldn't make a difference).
All I would say is be prepared that the quality may not be amazing and it may need a bit of tinkering to get the fit right. If your expectations aren't too high then go for it, I'm interested to see one fitted.
