My car's being tuned at the moment and the tuner can't seem to control boost. He's always leaned towards the 4" dump as myself and Varaitch both have the same tuner. But after seeing how the CES dump pipe flowed on the dyno, lets just say he's qutie impressed!My dump pipe is being sent back to CES so they can make up a 2" wastegate section, he's pretty convinced that this will be quite possibly the best way to go.

I'm running the XForce split dump and making 369rwkw on 16.8psi. That doesn't seem to be too different to others who run the 4" dump. In other words, there doesn't seem to be an efficiency issue compared to the 4" dump. Similar power at similar boost.

I am running 3.5" dump and 2"wategate feeder pipe and they were both made by brian at exhaust innovations, same guy who made typhoon_freaks system and they are great Link to comment https://www.fordxr6turbo.com/forum/topic/54923-new-exhaust/page/2/#findComment-874190 Share on other sites More sharing options...
HIRO F6 Member 1,817 Member For: 16y 4m 26d Gender: Male Location: Brisbane, QLD Posted 09/05/09 01:18 AM Share Posted 09/05/09 01:18 AM Yeah, I couldnt speak high enough of Brian from Exhaust Innovations. I too went in there with the intention of going 4inch and im chasing 400rwkw and then some. He said if the 3.5inch doesnt get me to where I want to be, he'll replace it with a 4inch at no cost. He must be pretty confident with it. It did have to have the dump remodified as the car wasnt able to control the boost levels when it got tuned first.
