i posted this on another forum but got no replies so ill try this one.. im looking for a new exhaust for my 89 crxsi... i want it to have a fairly quiet hum under normal driving conditions but growl under full throttle... what do you guys suggest?... and what about piping size?... im planning on staying all motor so i think 60mm piping will do fine... also, i dont like how the exhaust wraps around the right side of the gas tank then back around and exits on the left... is there a way i could have custom piping built and use a universal muffler and still get the same effect?... im thinking the fuel lines will be a prob but if not, which muffler to use?... thanks in advance
