What made you choose this particular product?
This is one of the only exhausts without a muffler and it is so worth the money there is no drone either because of the small resonator they added, for just being a catback with a stock downpipe this exhaust exceeded my expectations.

What made you choose this particular product?
Despite looking like a half cage, the harness bar retains an oem look to it as you can still reinstall your rear seat.
Is this your first time buying from this brand? Did you consider other brands?
Yes this is the first time buying this brand. I also considered Autopower but their "bolt in" cages required welding a plate in order to be considered safe.
Was it easy to install? Any installation tips that will help others?
Easy to install. Make sure you don't tighten down the bolts too much prior to installing the main harness bar so you have room to adjust. Also, removing the front seats make it easier to install as you'll have more space.
Once you've had a chance to use the product, did it meet your expectations?
So far I haven't purchased harnesses yet, but for how sturdy the bar is I have no doubts about it.
Any additional comments?
I would recommend to paint the bar prior to install.

What made you choose this particular product?
Sound and performance, you can get the same performance from the tomei or the z1 single but they all sound different, I liked the agency power the most
Is this your first time buying from this brand? Did you consider other brands?
First time, very impressed
Was it easy to install? Any installation tips that will help others?
Very easy to install
Once you've had a chance to use the product, did it meet your expectations?
Yes
