Hi all,

I have recently acquired a pair of HS2’s but will they work on my 998? The engine is completely standard apart from a stage one kit. I’m not looking for any performance increases as I know they won’t have much impact, it would simply be for the aesthetics.

They will give no performance increase, you may even experience a loss in performance as you will lose air speed in the induction side. You will also need a new exhaust manifold unless you cut up the original cast manifold if they will fit. Fitting the new exhaust manifold will really need a suitable exhaust system.

and after all that the carbs will need setting up to run correctly. All in all a lot of cash just for looks and more noise in the cabin.

If he already has the carbs and a stage one kit (as per the first post) then there’s potentially not a huge amount of costs to get them running nicely
