Hey ppl,

I just recently put Pacemaker Extractors on my ED Futura. The engine is stock and i have the standard exhaust still. Saving for another exhaust atm. Neways after i put em on the car went worse. It had a huge flat spot n just went crap all round. I took battery off n let it re-program n it was better but still didn't go better than with the original manifold???

Anyone got any suggestions why this is so EXCEPT buy another exhaust as i will when i got the money.

Thanks
Matt

If they are the norm pacey's they have very big pipes, not the best setup for falcons but ok, the problem you have now is that all this free flowing gas exits the engine nice and quick and then slams against the old cat and piping and the speed is reduced lots and backpressure should increase. the old system would have kept it all flowing at a constant rate, hence nice smooth accel and constant power. you should have gained some down low but lost up high. you wont get the upper end back till you get the rest done. anyone feel free to totallly blow me out of the water if im wrong.

Yeah i dunno if they r norm pacey's or not. How do i tell??

Anyways it seems to have a tiny if any bit of extra low down go but topend seems same as before. Neways i gunna go price an exhaust tonight after work. lol any suggestions on what i should go for??

Also it is leakin like a dog atm cause i had to modify my old exhaust to fit these on. Would that also help make it go crap??

Thanks
Matt

I've got the same setup - Pacemakers but with 2.5 cat and then the stock exhaust all on an EB2.

Not real impressive but then again you'd hardly call the 148kW from the 4.0 an indication of high performance. My biggest issue is a resonance that seems to come from the front muffler area at around 2500rpm

My money would be on the rest of the system as well. Try putting a 2.5" cat and pipes on, that should help a lot.

Have you noticed increased power anywhere in the rev range? How is your economy?

i had exactly the same result on my EB2 Fairmont. After is put the 2.5" cat back exhaust on and a 2.5" high flow cat, the car went like a rocket. We did back pressure tests before extractors, after extractors and after exhaust, and the figure with the extractors and no exhaust was huge.
Wack on a 2.5" system, and all will be fine.

Yeah I am puttin some money aside for the system now.

I fixed my DODGY (lol) bit of exhaust i made n now i seems to have tiny bit more pull to it down low but like what has been said it has lost top end.

I'm happy wit it atm. Also my ecomnomy SEEMS to have got better. I not sure yet as i haven't been on a long trip yet but around town seems like i usin less fuel which is always GREAT

I'll let ya know how it goes wit a full system on it

Thanks all
Matt
