Gains were minimal for the dollars Link to comment https://www.fordxr6turbo.com/forum/topic/68747-x-force-exhuast/#findComment-1015669 Share on other sites More sharing options...

Posted 14/06/10 12:57 PM Share Posted 14/06/10 12:57 PM Have the X Force mild steel 3.5" system with 4inch dump and metal cat on mine - sound / noise level is fine after the first couple of weeks and it coats up.... a little noisy initially. Beautiful burble on overrun. Check out photo's in my garage.

riki83 Silver Donating Members 384 Member For: 15y 3m 21d Gender: Male Location: Kellyville, Sydney Posted 25/06/10 07:06 AM Share Posted 25/06/10 07:06 AM I have modded my fg xr6 turbo and I have a 4"dump, 3.5" cat and exhaust. its supported me to 426 rwkw so far but I need to go bigger to support me over 450+.I will be upgrading to a 4"dump, 5"cat and 4" system which will be plenty as my exhaust was holding me back from extracting everything this car has. The next step will be a bigger turbo but that's not going to happen. This ute is crazy to drive and the exhaust does sound pretty good. Most people think there is a screamer pipe on it!!

Posted 22/07/10 07:36 AM Share Posted 22/07/10 07:36 AM I just emailed rapid yesterday about the xforce 4" system, is the 4" system overly loud or just louder than the 3.5" system cause I dont mind it loud personaly but dont want to get pulled over and done by the cops.
