I just slipped on the crusher exhaust on to my 08 SG. Man the differance over the stock pipes is huge. Now I know what they mean about coming alive when rolled on. I have not added stage one as of yet: ie race tuner and air cleaner. But I do have the python true dual headers in the garage. Is it ok to put these on, or should I wait untill I have all the stage one parts. Thanks in advance
