I have a '04 Audi A4 S-Line and I've been looking into upgrading the exhaust. My two options are
1) 2.5' custom cat-back w/o resonators and custom mufflers for $450
2) Magnaflow cat-back for $850

Both are priced including installation. I also want to add that with option #1 I will use the remaining $400 towards downpipe's as I know that this will improve my performance and the car's sound. But I don't know if the Magnaflow is worth it or is it just the brand name I'm paying for & custom is just as good.... let me know what you guys have heard about the Magnaflow. Pro's & con's. Any advice/suggestion is appreciated!

 

Go custom but with whatever mufflers you want.
