are you looking for a "Sport" manifold with a 200 cell cat or a "Race" manifold without cats? We are a dealer for the Cargraphic manifold that Jwade sent a link to. A lot of our 981 S/GTS and GT4 customers are very happy and they are something that have been in production now for over 5 years.

I am in Australia though, but would consider a used set even.

Additionally, I recommend adding an IPD plenum with the 82mm 997 GT3 throttle body. This combo really adds a nice level of performance, but you may / will throw a CEL with the IPD due to the stock ECU reading pressure outside the stock limits. My next next mod will be a software reflash to take full advantage of these mods, but have been on the fence watching what companies develop the best tune for the money...

Thinking about buying a Carrera 981 S and doing some performance mods. Based upon what I've read, I'm leaning towards an IPD plenum and larger throttle body, catless headers and modifying the stock muffler (carnewal). The only ECU flash I've found so far is by Cobb. Can anyone suggest another ECU flash and with these mods will I be in the 365 - 370 crank HP range?

We should be able to help you crank out another 40-45hp or so

Feel free to PM us with any questions. We'll be posting another thread showing the progress of our own 981 build. Just waiting for winter to thaw over so we can fully break-in our motor!
