Ok so im doign the exhaust on my 99 2.2....now i have a magnaflow replacement cat 2.25" with a o2 bung in it..but it doesnt say hi flow like my old magnaflow did without a bung....am i going to lose flow with this cat or should i get a magnaflow hiflow and weld abung into it? any hlp would be great....also any perforated resonators off hand that anyone can think of would be awsome..phil

Resonator = Thrush/Walker/Dynomax

The cat I'm not too sure on... I just changed over to a new Magnaflow cat that has a bung on it but I'm not sure if it is a highflow or not... I know it's OBDII compliant which your car's cat needs to be if you have emissions testing and don't want to throw codes...

Also I think that Magnaflow stopped making thier own cats and are selling Carsound cats under the Mangaflow name or something like that... So they may have changed the styling a bit to be more generic... (cheaper to manufacture that way)
