so i checked for leaks and sure enough there was leaks in the two downpipe connections so i took it off and banged the **** out of them to make them as tight as possible then covered them in high temp rtv and clamped them down off the car so i could go as tight as possible with a flex bar lol i dont think they are going to leak now only thing that sucks is i cant fit my cat that i got in there so i kept the downpipe for now but i got a 13 inch walker to put in and it wont fit with sleeves and clamps so im going to get it welded to the flange and downpipe and im thinking about getting the flex pipe cut out to and a new one welded in, Any recommendations?

still seems like there is a roughness in the pedal though and i looked at the o2 sensor there is no way its hitting the o2 wasnt bent at all the the clearance is plenty

how long will it take for the computer to pick up to lack of a cat and i know my car will run lean but how unsafe is it
