Bought these as new online a couple of years back as Agency Power units, but they are unmarked and I received no paperwork. So, consider them of unknown manufacturer. I used them for ~2K miles and found absolutely nothing to like about them & went back to the factory ones.
The Bad: When installed with factory mufflers they add an unpleasant metallic resonance to the exhaust sound. The sound might be more compatible with sport mufflers, but assume it won't be. They produced CELs a couple times during the time I had them installed - so, they're unlikely to pass an emissions test.
The Worse: You're probably not going to like them, either & have to swap back to something else.
The Good: They are made of stainless steel and lighter than the factory cats. May be an alternative to bypass pipes. Can't think of anything else positive.
I was going to buy these but you ad talked me out of it!
I have the Top Gear cats from the UK and they are awesome, more power, no cel and sound mean as hell. They look almost identical to yours, they must be different inside.
