I know that you need all kinds of tuning to get a performance increase but is there anyone one here whos can shed some light on making a set of stingers that will atlest keep around the same performance as stock just with a nicer sound. Just looing for something to do to keep occupied in the shed eveynow and then but i dont want to burn up the sled engine(its a 503 bombardier) I also have the stock exhaust just looking for some fun.
