One bajillion is right.
I think it would sell very well, especially whoever is the first to produce one at a reasonable price. Honestly I think 200-250 is still a bit high, but if it came with "all the fixins"(full 3", separated wastegate, ss, solidly built), I would still get it. But I can't really justify paying 250+ for about a half a foot of piping. Seriously, come on (jerkit)
This s*** is getting old though. I have seen countless threads that tease about a new s-pipe replacement, yet no one has delivered. The corksport one has been "in development" for god knows how long. Various other members have proposed trying to get a shop to make one, and selling to the community, but nothing has ever come of it.
Many people are VERY interested in getting an s-pipe replacement, and I think it would be a goldmine for whoever can deliver. If I had the tools and the skills, I would be popping them out day and night, and probably make a killing at it too.
Right now looks like perrin is the best bet, since they did recently come out with their fmic and they now claim that the s-pipe is in the works, but we shall see. At this point I am skeptical towards anyone claiming to have an s-pipe in the works.
