Figured i'd put all my latest q's in one thread to save space and time.
1. Which extractors are the better choice for my i6, pacemaker 4499's or 4490's (i've got a redback 2.5" catback exhaust)? 2. Will a hi-flow cat make any difference performance and sound wise? 3. I want a c2r front grille, now I can get one for the low profile or high profile bonnet. Does a Falcon (non-xr) look better with the high or low profile bonnet? Take into consideration this will be with a c2r grill too. I'm after a meaner/sportier look if that means anything. Pics would help. That's about it for now :P. Thanks for any answers.

I thought it was 4490's, maybe it's 4480's? I'm sure there are 2 types for the au 6.
EDIT: My bad it was 4480s.

4499s are better for stockish I6s, 4480s for cammed/chipped I6s. The 4480s work better mid-high rev range, the 4499s are more low to mid.
High flow cat will make marginal difference. IMO, the series 2 bonnet with the high C2R grille looks better than low series bonnet with squashed C2R grille.

You won't notice a big difference in power from a hi-flow cat man, i just got one put on a couple of weeks ago..there is a slight difference but not too much and no it doesn't change the sound of the exhaust note or anything.

RTSW, I have 4499's on my AU which is not stock. 4499's were chosen for mine to give mid-high as low-mid was going to be covered by the hi-stall. Had I not gone with a stally, G&D would have chosen 4480's to help pick me up low-mid, especially being cammed. Hope that makes sense lol.

Refer PH4499. Will not fit XG ute. It looks like the design of the 4480s has changed somewhat - they used to use a larger primary, so given the smaller secondary of the 4480s, these may in fact produce better torque down low, which means Krissy is correct.

The 4480's seem to be the most popular but I was speaking personally about my car. With cam and stall, the 4499's are what was needed for my car as we knew the stall would take care of the low down lag caused by the cam. But then what works on mine may work very differently on others. At the end of the day, everyone will have an opinion. I posted mine ![]() RTSW - Just go to a reputable place. Take their advice and fit what they recommend.

What I will stand by though, is that if you have a VCT motor, you'd be mad not to fit the 4480s (just ask Casper). The 4499s are better suited to the intech version of the AU I6.

the high profile with the C2R is the go www.aufalcon.com/au3xr6 here is my car if you want to have a look as for the extractors it depends on your engine / mods and where you want the power made the 4480 tends to make the power up higher and is more suited to a modified engine ( cam flash tune etc)

Alright, thanks for all the answers! (Nice pics ;))
I'll be definitely going with a high profile bonnet and c2r grille now. As for the extractors... Well i'm thinking the 4499's. My car is stock except for the exhaust, k&n and xr6t snorkle. If I can be convinced otherwise i'd be happy to. I'm more after torque and power in the low to mid range.

Meh , Im in the same boat as you are , after you do some exhaust work and put the Headers on , its like a different car. But the Laggy Shtuff from down low in the I6 can only be ridden with either a Stall and a Cam , or Supercharge it.
My Car was the same as yours , Pulled 108.4 stock , and now its making numbers just with a few minor things , Exhaust , Cat , Headers and all that CAI Jazz.. Cheers and hope this is a Guide to what your AU will do in the Future ![]() Daniel

I got the 4480's, didnt loose anything down low, in fact, I 60'd better with the 4480's then I did without them, but in comparison to the 4499's, I have no idea, never actually seen them tested side by side.
Just so you know, Intake, comps, 3 inch zorst, and a generic tune, 2.19ish 60ft's, stocko driveline (no LSD, 3.08's, no stall ![]()

![]() ![]() Now i've said that, the pacey comp's are really good above 3000 rpm and then they really pickup at 3500 rpm. So you have to ask yourself what the car is being used for. If you drive the car really hard or it see's heaps of track work then you are probably wanting the pacey comps. If its just a daily driver and your not going to have it operating above 3500 rpm a lot then go for the normal pacemakers and you also saves yourself some money to. The cheapest way to get the paceys is to ring Magnum Exhaust in Dandenong VIC as they are the wholesaler and just tell them your going to fit them up yourself. Pick up the comps for $470 plus $100 ford your local exhaust shop to fit. Otherwise you will pay $700-800 even $1000 if you ring G&D Performance. Normal Pacemakers wholesale for $350.

I dont think it gives too much drone at all, if any, although it is loud, and sounds almost like a Saloon car. Bear in mind I have no res, and a single 3 inch straight through muffler, and 3 inch cat.

![]() I just had one follow up question if anyone knows. Given there are (at least) 2 designs of pacemaker comp 4480 going around. And given that the later one is what I am looking for. And that I was trying to buy 2nd hand to save some money. Is there any way I can identify an earlier from a later design? Apart from a caliper to check those external measurements? Or is it just going to be safer paying $600 for a new set? |
