SHOWDOWN BACK SLOWER THEN EVER! Member 706 Member For: 17y 10m 19d Gender: Male Location: Sydney Posted 17/12/07 12:49 AM Share Posted 17/12/07 12:49 AM Nice work.The standard dump is a 3" out so yes it wil mate perfectly. The next restriction is you mufllers. Maybe get the centre replaced with 2 hotdogs and get the rear as a 'hiflow' and you should be right. For memory the pipes inside the mufflers just under 2inch so they are quite restricting.Ozzie Link to comment https://www.fordxr6turbo.com/forum/topic/40601-35-metal-cat-fitted-to-std-system-today/#findComment-609755 Share on other sites More sharing options...
Full Monty Member 513 Member For: 17y 10m 29d Gender: Male Location: Melbourne Posted 17/12/07 01:23 AM Author Share Posted 17/12/07 01:23 AM The rest of the standard system flows just fine, and only worth changing if chasing 350+rwkw.The 3.5" Metal Cat mates to the standard Dump fine, it requires dump to be cut to remove the original welded on factory cat, and then flare the end of the dump pipe to 3.5".The original system is tricky as it has twin 2.25 pipes exiting the cat, rather than a single larger diameter into a twin collector.What I had done, was to exit the 3.5 Cat, to Mandrel bent 3.5" pipes for a good 40-50 cm, before a Collector to mate to the standard pipes, ( a fair bit before the first flange at the first muffler.It may have been even better to continue in 3.5" back to the first flange.so when I sell the car, I can do a direct swap with someone back to standard if I wish, just unbolt 4 bolts and direct swap.Will take picks when I get the car back from nizpro.Coincidentally I was doing some maintenance on the car yesterday as well as fitting the new cooler. and when checking the exhaust manifold bolts I found the 2 underside studs holding the turbo to the manifold had dropped out..only 2 studs holding the snail on!.....I had strapp ford tighten all of these just 8,000 km ago at my last major service...Nizpro are replacing them with inconel studs and locking nuts. The main manifold bolts had loosened slightly, I am going to look into replacing them with better quality bolts and nordlock washers...cant be F'd doing that every 7,500 kms.cant wait to get her back tonight.
