Going to talk too an exhaust bloke I know and see if he can modify the pacies 4499's with longer secondaries.............The fairmont runs a dream at the moment with the XR6 ecu 6JDA and XR6 fuel 300KPA reg.......... Soon too replace the stock 400CPI cat with a 200 cpi item........ cheers.............

WTF? 4499s make you launch slower? Even if you just plant the throttle from a standstill the stalls about 2k rpm which is well into the zone where these extractors will give you more power. If its a manual and it feels slower stop trying to launch it off idle in 2nd gear.

The car I bought a year ago was an auto EF mont. Fitted 4499s and a catback - noticeable improvement.

WHen I got mine fitted on the AU Xr6 there was a noticable gain, the car didn't sound to great at first but then when it carboned up it sounded great, give it time and let the ecu learn

So you reset the ecu by disconecting the batery for halfa?
Krisisdog- my 5speed feels slower off the mark. |

I have 4480's......I didn't notice any loss in the bottom end, but did notice big gains in mid to high end. I haven't increased the CR, or fitted a cam. I have however p&p the head.

Ok this morning I reset my ecu and car is much better.
But still sluggish off the line. Maybe I need to practice. |

Getting there.
My old car would launch hardest from around 2400rpm but it was a prelude so redlined at 6200. Looking for this "hot spot" tonight,seemed to launch hardest around 1200-1500. |

With a manual, the hardest launch is around 4-4400rpm. It feels smooth, not fast, but watching 60' times at the drags proove it is the fastest.

1500? No wonder you cant get off the line lol. More revs, more clutch slip.
