What made you choose this particular product?
Sounds good, good sound for price.I have friends who have flow master.
Is this your first time buying from this brand? Did you consider other brands?
First time for flow master. Was looking at Borla but the price tag was just too much. Borla is more expensive because they use 304 stainless steel where flow master used 409 which is a less durable version of stainless steel, and has been known to rust out.
Was it easy to install? Any installation tips that will help others?
Need a lift or need to cut exhaust out if on ground. Lay out parts first and have clamps ready. Overall wasn't bad at all.
Once you've had a chance to use the product, did it meet your expectations?
Yes! It is loud and sounds good. Time will tell about the rust issues.
