Hi guys,
I have split front s steel dump / front pipe running into my 4" HKS Hi Power Exhaust into a standard catco cat converter.
I can get the CATCO Metal Cat 4" Catalyic Converters at a reduced price from a friend and they claim to flow at 1054 CFM
or I can buy a METALCAT 3.5 Inch Cat Converter and have to run 1/2 inch reducers to make it fit. (they dont make 4")
I think going down in size is stupid and i should go with the catco even if their CFM claims may be a bit overrated.
I need some advice guys.
Thanks
