What made you choose this particular product?
3" exhaust was a must for me, flowmaster has a very good quality product and it sounds amazing
Is this your first time buying from this brand? Did you consider other brands?
Yes first time buying Flowmaster. I considered the AWE Track but it was backordered
Was it easy to install? Any installation tips that will help others?
Slightly challenging. A tight fit and you need to cut the stock exhaust in half to remove it. If you've done this kind of stuff before its super easy
Once you've had a chance to use the product, did it meet your expectations?
FAR exceeded my expectations. Sounds way better in person than in videos
