[rcgbob44]

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.

Is that a 50mm system all the way through?....also, who makes the PCIII chip? (Power Commander?) I guess its programmable?

PC111, as in Dynojet Power commander 3, ideally you want the USB (PC3 USB) version as you can set this to advanced setup where each cylinder can be mapped seperately, you can also have the Accelerator pump option initialised and setup. It piggy backs off the original ECU by tapping into the injector wiring (easy plug and play installation) and also takes a tap off the Throttle position sensor, and allows the tuner to play with the injection opening times to optimise the air/fuel ratio through out the rev range and from closed to fully open throttle

Yes, 998S has 50mm system.

from my reading the 50mm headers with 50/54 midpipe and 54mm end cans is the best way to go as the full 54m system adds top end (9.5K rpm+) power at the expense of more usuable bottom end and mid range

also you will prob need to open up the air inlets in the nose fairing as this is a bottleneck. filter choice can make a big diference too.

forget a Power Commander (unless you have a very cheap one sitting round already), get your ecu repmapped by

BSD or CJS Racing

it will cost the same money and be better than a PCIII and dyno time anyway as more factors can be adjusted and at higher resolution than the PCIII

Thanks for the response, the 50mm headers with 50/54 midpipe and 54mm end cans is the way I would like to go. I already have the chip fitted which came with the 996r to support the 50mm Termignoni end-cans (and complete 50mm system), would this need to be changed?
