What made you choose this particular product?
Had a friend at a automotive shop that took it off a customers car and was going to throw it away, so I was offered it for $100.
Is this your first time buying from this brand? Did you consider other brands?
Yes. I was actually looking at Gibson exhaust but I couldn't pass up the deal.
Was it easy to install? Any installation tips that will help others?
Easy install. Cutting is required on the factory exhaust and it's a little awkward to remove the stock exhaust by yourself.
Once you've had a chance to use the product, did it meet your expectations?
It's loud and drones some but with a manual you can keep the rpm in the right range to avoid this. Sounds great, almost like a VQ from a 350Z/370Z but a little raspier.

Any additional comments?
Stock exhaust, cut a 12in section off after the cats which are gutted. Love the sound, love the look of the exhaust tips so 90% of the exhaust is still intact.

Despite for a little 4 cylinder it sounds good
