I'm on the east coast of canada, where if you don't know, we do not have to worry about smog and as far as i know allowed to not have a catalyc converter on any car made before 1991. that being said i have a 90 240 coupe and need to replace my current cat. would i gain horsepower by removing it and putting in straight pipe or would i be better off purchasing a high flow cat. if i put in pipe how loud will it be??would it backfire???
