What made you choose this particular product?
One of the reasons I had bought this exhaust was I had a Borla system on a 2017 Corvette Z06 and the system sounded great and working with the company was a pleasure too.
Is this your first time buying from this brand? Did you consider other brands?
No, it is not my first time buying this brand and of course, I considered of buying other brands but that's just doing other shopping to see what I would like for my car.
Was it easy to install? Any installation tips that will help others?
I installed it myself on my car lift and it was straightforward and simple, the only thing is I would recommend you have 2 other people with you when taking the factory one off because it is one piece and very awkward.
Once you've had a chance to use the product, did it meet your expectations?
The exhaust for sure met my expectations and even exceeded them.
