i recently installed a thunder header. i am now catless and my corksport exhaust is a lil too loud to be a daily driver. do you recommend i weld in a high flow cat or install a muffler to tone it down some?
High flow cat isn't going to tone it down that much. I don't know how much is "too loud to be a daily driver", but replacing a factory cat with a high flow aftermarket cat bought me a 8 dB increase.
