GM AFTERMARKET EXHAUST AND INTAKE
Ok so its that time for intake and exhaust upgrade, there are tons of exhaust and intakes for the camaro V6 but my question is how much horsepower increase does the GM "airbox" ( intake ) and the exhaust give ? only reason I am considering GM parts if for warranty issues, and please I dont need any comments on the warranty and what it covers and blah blah, i just want to know how much horsepower each mod will give if anyone has that info please share. Thanks
