I was looking to make a custom downpipe for my EVO. I have a couple of questions.

Will the stock O2 housing take a 3" pipe flange?

Any recommendations for the stock lower bars that the exhaust downpipe has to fit above?

Anybody running a 3" catco universal converter with problems?

Will the stock cat bolt up to a 3" system?


If anyone has any tips it would be greatly appreciated.
thanks.

Joe
