They are a weld in type for the XR6T. Should weld straight in with the 3" ends. According to Sureflo Exhaust it will flow 706cfm. I am sure they are 200cpsi as well.

It's the 3" (5" body) catco that flows 706cfm, ballistic is less I believe.

The cataytic converter section of the exhaust bolts in between the dump pipe and the catback. Surely the pipe from the dump pipe being 3inch to the cat exits as a 3 inch out of the cat? I thought that it splits out from a 3" to twin 2 1/4" after the cat, therefore there should be atleast a bit of room (say 5cm for example) to fit it in both ends.As fr cat flow, I've got no idea what Catco flows but I quoted those specs from the Surelfo website about the Ballisitic cats.http://www.surefloexhaust.com.au/frame1600x1200.htm Link to comment https://www.fordxr6turbo.com/forum/topic/48921-cat-struggling-with-what-t-do/#findComment-724035 Share on other sites More sharing options...

On a BA the cat itself has a twin exit. On a BF it's a single 3" exit.

Surely with the factory setup you must have 4 pieces with the factory exhaust being dump pipe which bolts to cat section, cat section which bolts to intermediate pipes and last section being the tailpipes. If you're telling me that the middle section of the exhaust isn't actually an independant peice, but rather welded on to the cat section, then it must be a bloody long peice of exhaust. If there's a cat replacement needed under warranty Ford woud have to replace half the exhaust. Doesn't sound right to me.

The cat downpipe section is probably a meter long.

They don't mention any WA distributors on their website at all.Roughly whats the price for one of them as well? And does it hang down pretty low on the car (scrape much?).I need one fitted early next week heyCheers!!!

You won't get one in Perth unfortunately. They actually sit higher than the factory cat so no scrapage.
