I have been reading old post on exhaust and I have narrowed the good ones down to three main choices. They are Apexi Worldsport, Tanabe Racing Medallion, and the Greddy SP. I already have a header but need everything (including cat) Which muffler, cat, and size pipping would be the best and the most afforable route. I want the less restriction with less noise and at the less price. I don't mind spending more money but If I could spend less then better for me, hope you all got that. 96 Civic DX / D16Y8 / AEM CAI / DC Header Which muffler / size piping / cat to use? Thanks in advance.
