My 92 LX has a 347, LT headers, H-pipe, Flowmasters. When I purchased the car the PO had already deleted all the smog stuff (TF heads).

I do not like running with out catalytic convertors, but do not know how effective they'll be without the smog stuff.

Will they be effective to some degree if I add a catted X or H pipe?
