Phoon508 Member 188 Member For: 12y 4m 9d Posted 24/04/14 05:48 AM Share Posted 24/04/14 05:48 AM Hey guys. I picked up an exhaust second hand. The rest of the exhaust is xforce however I am not sure if the cat is the same brand. Anyway, has anyone else got one of these in their high flow cat? Not sure If I should knock it out or not because it seems like a big restriction to me. Any info on it would be great. Thanks! 1 Link to comment https://www.fordxr6turbo.com/forum/topic/88080-high-flow-cat-restrictor/ Share on other sites More sharing options...

That would make for interesting racing Link to comment https://www.fordxr6turbo.com/forum/topic/88080-high-flow-cat-restrictor/#findComment-1467522 Share on other sites More sharing options...

Phoon508 Member 188 Member For: 12y 4m 9d Posted 25/04/14 07:55 AM Author Share Posted 25/04/14 07:55 AM Thanks for the reply guys. It really had me puzzled when I first saw it. I'd say that you would be spot on ratter. The guy I bought it off didn't seem to know a heap about these cars and his tuner wasn't anyone I had heard of. He is after a 600hp car as he had just bought a gt40, yet his tuner told him that the factory replacement 'monza' cooler would get him there....Anyway, after sticking a torch into the cat today, I have found the core to be rooted. I'll probably just look to buy a new one but I have to ask, is there any performance gains to be lost or had with just punching the core out? Now I know all about the EPA fines and such so I don't want this thread to head down that path. Also does anyone know how much a new xforce bolt in cat is worth?Cheers guys Link to comment https://www.fordxr6turbo.com/forum/topic/88080-high-flow-cat-restrictor/#findComment-1467539 Share on other sites More sharing options...
