Well you can go with a MBRP Diesel Performance Muffler and change your intake to 5 inch, stainless steel, straight drop in. Part #M79M2050 about $130. It's not real quiet either and it's not going to give the little 4 cyl anything noticibale (audible yes). The drop in like OEM muffler is a Bosal B0166049 for about $45 - and I guess you will need the tailpipe. Good Luck!
