Exhaust upgrade or powerchip

Hi all

Had my AUII Fairmont for just over 4 months now & decided it's time for more power. Considering 2 options, new exhaust - at least extractors, or powerchip. Has anyone had a powerchip installed and if so what was the result. Advantage of the chip if it works is it can't be seen when you pop the bonnet like extractors can, so you can keep the mod secret from the insurance co. Anyone who's done the exhaust, what was the result.

Re: Exhaust upgrade or powerchip

you are much better of with a full exhaust system being installed than a POS powerchip. Do a search for powerchip and you will find out why. Big waste of money it is IMO.

Get some extractors, 2.5" mandrel bent pipes and 2 straight through mufflers (MUST BE PROPER STRAIGHT THROUGH), not baffled, triflow types.

EDIT: Welcome to the site Im sure you will find it as usefull as I have

Re: Exhaust upgrade or powerchip

Do the exhaust, even if you want to do the chip you will still need to do the exhaust if you want better results

Re: Exhaust upgrade or powerchip

If you're after a chip, go ChipTorque. At least they use a Dyno...

Even then, you'll get a better increase in power from a full exhaust system. Then do the chip as the next step.

Re: Exhaust upgrade or powerchip

Best to do all mechanical mods to car before any ECU changes are made. That way you will get the full benefit of the Chiptorque chip or Unichip or whatever!

Re: Exhaust upgrade or powerchip

I agree with everyone else, chips are a waste of money on standard(ish) engines.
The standard ECU works very well indeed on the standard engine, and even when mechanical modifications start, the ECU copes quite well.
It's only when serious engine upgrades are made, you may need a chip and some dyno tuning.

The standard exhaust and manifold, OTOH, are complete garbage and don't flow very well at all.
Extractors and a decent 2.5" system will give you at aleast 10kw more power right across the range.
