First , some background information. If you are like me, you've already spent about 1,000 man hours on the computer searching for every exhaust review in existence and you've watched the same exhaust clips on youtube so many times that they start showing up on the trending page. Been there! I had my search narrowed down to Magnaflow. More background information: I'm young, I'm not married, and I have no kids. I want my exhaust to set off car alarms from a neighborhood away. With that being said, from my research I found that there are two opinions on Magnaflow. 1. It is one of the loudest exhausts out there. 2. It is a pretty quiet exhaust, just above stock sound levels. At this point I realized reading other peoples reviews were pointless so I bit the bullet and bought the exhaust. The build quality was a 6 out of 10. One weld went through the exhaust tip and created a large bubble inside the muffler. I debated returning it but decided to keep it. Install was easy but the exhaust does not clear my bumper on the right side so I ordered kartboy long exhaust hangers. The exhaust sounds great so far, it's a nice medium loud rumble with no drone thus far. If I had the choice, I would consider a different exhaust like namless performance.
Pros: Easy To Install,Price,Sound.
Cons: Build Quality.
