I'm assuming that the magnaflow mufflers are much better quality? Should I be assuming that?
I chose the magnaflow simply, like you said, for the quality. Looking at the link you just posted, it is clearly evident the quality differences between that and the magnaflow. When I opened the boxes for the MF mufflers you can just see and feel the quality. I have a magnaflow X pipe on the way (part number 10791) to replace the OEM "shitpipe" because the MF pipe has a bigger opening in the crossover. I have deleted the secondary cats and put in straight SS 2.5'' pipes in its place. This, combined with my new resonators I have on the way as well will create a unique sound, and maybe gain about 2-4 horses with the new x pipe, as well. Nonetheless, my muffler shop guy charges me literally almost nothing compared to other customers, so I have saved A TON of money by going the "custom" route as opposed to dropping thousands of dollars on something else. It allows me to experience the different aspects of playing/toying with the exhaust and finding something that I will love!
