What made you choose this particular product?
I bought this exhaust for the sound. It gave the car a deeper sound rather than a high pitch raspy sound. It also made the car louder.
Is this your first time buying from this brand? Did you consider other brands?
First time buying this product. I did consider other brands but this one had the sound I was looking for on the car.
Was it easy to install? Any installation tips that will help others?
It was a little hard installing the exhaust on jack stands. A lift would be easier.

What made you choose this particular product?
perfomance and old Original exhaust was rusted out.
Is this your first time buying from this brand? Did you consider other brands?
yes first time, other brands did not have an option for a custom exhaust, the primera is not popular enough for ready made systems.
Was it easy to install? Any installation tips that will help others?
it was professionaly installd by Crooke tuning.
Once you've had a chance to use the product, did it meet your expectations?
works well with the previously installd exhaust parts, causing the old engine to make good power up top without losing torque down low.
Any additional comments?
propely tell the workshop people what you want, then they can make the exhaust fit to your taste.
