Firered Posted August 12, 2005 Report Share Posted August 12, 2005 Do you get better gas mileage with installing a Cat Back exhaust system or not ? Link to comment Share on other sites More sharing options...
jboyss Posted August 12, 2005 Report Share Posted August 12, 2005 well im not sure if you do but if ya did it doesnt matter anyway becuase you wont be able to keep your foot off the gas. At least thats my problem i just love to hear the exhaust. Link to comment Share on other sites More sharing options...
