My research brought me to Fast Intentions as the best alternative to OEM cats for my application. I wasn't looking for the sound to change drastically or get much louder. A group buy for these opened up so I placed my order and began waiting.

The RHFC showed up about 3 weeks after the group buy had ended, right on schedule. Immediately, I ripped open the box to a well protected, very well packaged product. Unfortunately I didn't grab any pictures at first because I got right into tearing apart all the bubble wrap I was pleasantly surprised when the cats were out and they looked absolutely flawless. Immaculate welds, great look, just an overall very well built pieces.

Picture right after taking them out of the box. License plate frame was a nice little added bonus I thought as it was not expected.

Right after the picture I was very eager to install so into the 20 degree weather I went to get these on.

The installation went flawlessly minus the cold weather and stubborn bolts. Fitment was spot on and actually probably sat slightly higher than the oem cats, which I think is a benefit. After buttoning everything back up on the car I was working myself up to finally start the car (very nervous at this point), given my previous HFC experience.

All I have to say is WOW. I was completely amazed at how these sounded right away. A nice mellow similar sound that was there before, only deeper and slightly louder.

I have had these on the car for 3 weeks now and my impressions haven't changed one bit. Still absolutely in love with this product.

Sound while driving is definitely louder than OEM cats but surprisingly the cabin noise increase is negligible. Didn't really notice an increase at all especially regarding drone which the Kinetex had immense amounts of. These did not create one bit of added drone. Offers a nice mellow cruising tone, but when you put your foot down they can scream. Rasp that is typically associated with changing to other than stock cats is also basically non existent. The Megan Racing exhaust I have had on the car has always given a hint of rasp by itself and these didn't add to that at all, but I wouldn't say they killed it either. I am possibly thinking off adding a resonated Y pipe to my system as well in the future, but at the moment am thoroughly enjoying my new exhaust set up.

Here is a compilation of the different exhaust set ups I have had so far.

I would highly recommend this product to anyone that is looking for more power with a slightly louder, deeper exhaust note.
