Hey guys, My exhaust system has developed a few leaks over the course of the winter, causing a check engine light with the O2 sensor. Given the state of the flex pipe and the resonator, I'd like to replace the whole system all at once, from the 90° tube with the flex pipe on it, to the muffler. I am inclined to buy a more free-flowing exhaust, but I don't want anything too loud so as to maintain the understated look and sound from the factory. I'd go for fabbing something myself, but I don't have a welder and labor can be quite expensive where I am in Michigan. Additionally, my Accord has the F23A4, and I am not particularly sure if that has any bearing on anything besides the catalytic converter. I see that Magnaflow has a catback exhaust for the 4 cylinder Accords, but I have no clue if that would be too loud or ricy for my liking.(Pricy as well) Thanks!
