JdmJohn Posted August 22, 2009 Share Posted August 22, 2009 My 93 civic has a stock exhaust piping all the way up to a fart can.. literally he got it from ebay.. I got a dc muffler i want to put on the car.. but i was wondering wat size piping can i do from header back.. we have no loudness laws, or a law that i gotta have a cat.. i'm not going to do no b series engine swaps. just gonna build up the d16.. btw i did search forums.. http://www.andysautosport.com/honda/1992_1...sp00011555.html Link to comment Share on other sites More sharing options...
