I have a 998s and when I fitted Termis and a PCIII and had it set up on a dyno I enquired about fitting a 54mm system. The man said yopu would gain about 1-2 HP at the top end but loose lower down. H e did say it's only worth fitting if you have head work done at the same time. I'm very very happy the way my 998s goes now.
