I do believe you are correct they seem to be a little diffrent than the Chinese exhaust. I'd say they are the same as the Topspeed. I think he changes very little just enough as not to get in trouble as a copy. I own this exhaust and headers for the 3.2L. I can't remember where (wish I did) but I came across the original stuff one night surfing the web. When I had the stuff sitting in my house before I put it on my car, and it was identical. The prices might make you second your thoughts $2,100 for headers and $1,900 for exhaust. The quality on Che's is remarkable and he does sell a lot of Topspeed. I know that it was a perfect fit and I have had no problems with the flange on the headers or internal issues with the exhaust. (over a year) I'd buy his and not the other ones... Hope this helps.
