What made you choose this particular product?
This was a choice made by the guy who worked on my exhaust system.
Is this your first time buying from this brand? Did you consider other brands?
Yes, this is the first time I'm using a Magnaflow muffler.
Was it easy to install? Any installation tips that will help others?
This was installed professionally.
Once you've had a chance to use the product, did it meet your expectations?
It's a bit expensive for a muffler that can be found in the same style for cheaper. It does help the system flow a lot better though. The car even pops and burbles on downshifts, sometimes even on upshifts. It's a little too loud in my opinion, but It's what happens when you get a straight-through design muffler. If it was a little quieter, it would be perfect. My car isn't fast, and it doesn't need to be super loud. On the upside, it helps make my presence known to others around me since my car is on the small side.
Any additional comments?
Make sure you protect the welds with a little bit of paint so it doesn't rust.
