I have a stock 99 honda accord coupe 4 cylinder. I want it just to have a more punchy sound without being overly loud in the cabin. I could drill holes but im looking for something done right! I just have no idea how to pick out a muffler for my vehicle. I am looking to increase mpg most importantly though. I maybe considering some sort of coldair intake as well. Or is all this pointless on a 4cyl automatic??































Thank you!!

well you made a poin with a stock moffler you get exaust restriction that means about 3 to 5 hp cold air intake its a good idea or just keep a stock air filter and remplace with a k&n that would save you gas, and use a lucas injector cleaner and remplace fuel filter (its cheap) whenever you do oil change . with the muffler go with something like trust it would be cheaper than any japan made muffler with that it will be like 12 hp max for 200 dlls or more
