are these available for gen 1 997 turbos too?

 

Beautifully made pieces. I had an inconel exhaust manifold on a B5 A4 I had back in 2000 that I upgraded to an APR stage 3 kit. Unique material basically perfectly suited for turbo manifolds. Awesome job BBi.

 

As of right now, these are only listed for Gen 2 997.2 Turbos.

 

totally want these for the sound, throttle response and power.

 

It's an outstanding upgrade with all of those benefits! Feel free to email us if you have any questions!
