And johno bruce says without a doubt going to twin 2.5 or single 3.5" this car will open up and see massive power gains. He actually said the system on it is a downgrade from the stock system in his opinion. Ill go 4" dump and twin 2.5s with no cat monday. Should make a giant difference. Nothing else really explains why adding a cooler kit and turbo side 4inch intake wouldnt make any difference in power according to bruce.

FiftyOne Bronze Donating Members 1,145 Member For: 11y 10m 14d Gender: Male Posted 02/03/14 06:39 AM Share Posted 02/03/14 06:39 AM I've previously working designing vacuum trucks. Awesome adaption of technology in those things. Knowing what I know from those things, I would take 2 x 2.5inch pipes over a 3 or 3.5 single any day of the week. The 2.5 pipes will have a higher gas speed running through them, there will be less tendancy for pulsing in the pipes (creating drone) and will be quiter. Other option is for a 'J' pipe arrangement. I was skeptical but a very good exhaust fitter I know fitted one up as a request for a customer. He didn't think it would do sh*t but we all ended up very supprised. If I was going down the road of big streetable power, I'd seriously concider a J pipe Link to comment https://www.fordxr6turbo.com/forum/topic/87641-restricted-at-330rwkw-due-to-3-exhaust/page/3/#findComment-1458313 Share on other sites More sharing options...
