Anybody know if here is an aftermarket manifold for a S5 TII? One that I can bolt up to the stock turbo (modded BNR stage 1) and downpipe. I would think that tossing the stock manifold would improve power. I saw some on ebay but dunno about the quality. Anybody try one of these?

 

ive got one of those SSAC ones thats on ebay everyone here says they suck but I havent had any problems with it.

 

But they do suck. Search up and it WILL crack. I think Karak has the only one thats done its work.

For a manifold, check my sig .

 

I don't think you've looked very closely as the S5 exhaust manifold before deciding this. Assuming you want to keep the turbo in the same location, how is an aftermarket manifold going to improve on it? You would have to use the same pipe size and route that the stock manifold takes.
