JJ77 Posted August 17, 2005 Report Share Posted August 17, 2005 Are you looking for a full cat-back or just a muffler replacment ? If you want a full cat-back it will run u between $400-$600 dollars depending on what mufflers you use and what shop does it. Get 2 1/2 inch pipe ran from the cat back to behind the rear wheels then y-pipe it to 2 1/4, then finish it off with either of these. http://cgi.ebay.com/ebaymotors/MagnaFlow-Muffler-Street-14807-14-x5-x8-Universal-Fit_W0QQcmdZViewItemQQcategoryZ33636QQitemZ7993506538QQrdZ1 or these and add your own tips http://cgi.ebay.com/ebaymotors/MagnaFlow-Muffler-4-x-9-14-Body-2-1-4-O-O-11235_W0QQcmdZViewItemQQcategoryZ33636QQitemZ7993857083QQrdZ1 Don't forget to add a resonator between the cat and the mufflers or it will sound really rASSpy If you want just mufflers then just buy something like the ones shown above in a 2 inch outlet and a shop would only charge you $50-$75 Quote Link to comment Share on other sites More sharing options...
