Unless they came out with it now..(been I while since I looked) the Magnaflow is only 409SS which is a low grade of stainless steel. I would recommend at least a 304 grade if you plan on keeping it. I have the borla myself and I love it. Its not overly loud while cruising but mat the throttle and you can sure hear it.

The people at Magnaflow say that they fixed the tip falling off thing a while ago though.
