Which member was that?

Edit: Sorry, I should be more specific as you are actually referencing me. The AMS pipes I have are intended for Alpha turbos. Larry from AMS informed me of this and I am not having any problems with the fitment. Something else happened to the car during the install, but up to this point I haven't been able to nail it down. I wouldn't be afraid of either product, but the AMS pipes are more rigid and larger.

Take that information and do what you like, I think the do88.se pipes are fine as long as you can get them (apparently they sold out).
