Re: Exhaust System Suggestions on 3.9L XF Ute
First of all, Carburettor versions of the XF only came out in 3.3l (200ci) and 4.1l (250ci). Assuming you have the 4.1l I would recommend to go a 2.25" Lukey exhaust, I've got one on my XF ute and it sounds fairly tough - also have genie extractors. If it's carburettor you mightn't have to worry about a cat, check your current set up, is there a cat there? If not, I wouldn't worry about it. Best bet is to talk to a Exhaust specialist and listen to what they recommend because they have most likely done it numerous times before. Post up some pics of your ute, good to see some more utes coming on the forums!
