silver_coupe Morning people i have an astra coupe full custom chrome exhaust, from cat back staight through im looking to get more noise, would you suggest the pre cat to be removed.....
Sjdickso What year is your car? some of the later ones didnt even have a pre cat, mines a 2003 and didnt have one in. Not sure it will make that much difference noise wise but may sqeeze a ponny or two or out of your car.
