Anyone swapped a set of 40-series for Super 40s? Hows the drone? I'm thinking about swapping my Magnaflows for Super 40s after I get my cams installed because IMHO nothing sounds sweeter than a cammed car with chambered mufflers
that the way it usually works out unfortunately. tons of people who "know" something but only a couple who really have experience with the issue.nickthegenius said:Yeah, I just read through a bunch of posts. Many people asked the question but out of all the questions I only found one guy that answered that he had them and it was better than regular 40s. All the rest were specualting about the subject citing Flowmasters promotional ads, etc.
