So today I finally was able to get my S60 R-Design to a custom muffler shop to replace the muffler with a Magnaflow Camaro muffler. The exhaust shop was recommended by another mechanic I know so I was feeling pretty confident and this is something I've been planning to do since I got the car last year. Now I'm wondering if I got an actual Magnaflow muffler, or some other brand. My concern is that there is no Magnaflow brand stamped on the actual muffler. Does anyone on here know if all Magnaflow mufflers have their name stamped on them?
