Also if you want a little more for sound, get a plenum spacer...cats+plenum space + stock exhaust sounds awesome...it really roars when you get on it, but otherwise it purrs.

+1 on the mounting issues. This is the main reason why I haven't picked up Cats yet. I am trying to find a set which are reasonably priced which use the stock mounting brackets. If FI modified their setup to use the tranny mounts, then I probablly would have bought those already. I have a FI exhaust waiting in the garage to go on before spring and I will probablly just install the cats and the exhaust at the same time.

I can personally vouch for what Tony is saying. I have the FI exhaust and HFC's and they work perfectly together. There are no issues at all due to no mounting brackets. The fellas at GTM also commented to me what a nice setup the FI exhaust and cats are. You will not be disappointed at all.

Having the brackets on was a nice thing, since there was really nothing to lose even though they aren't proven to have a significant effect. But having them off shouldn't be an issue either.
These brackets are something I can live without. The quality, fitment, & craftmanship of the test pipes I installed are top notch (although im sure the brackets are not really there to address the issue of quality or fitment).

Haha high flow cats, i wish i was doing that again To the O.P you shouldn't be worrying about anything, its only Cats man haha, simple and easy to install stuff and worth the mod. I'm using the Kinetix HFC and honestly like it, but if in my opinion, Fast Intention all the way!!! No questions ask, no point in researching more, get F.I! Get it and it will fit, dont trip

One of the most important things an enthusiast should do is research their @ss off!!!! Not only to determine specifics about the product they intend to buy, but to feel 100% confident that they made an "informed" decision.
This is true for any purchase - not just automotive. I researched bed manufacturers, TV, Computer, etc... I don’t base it on money; I base it on usage... If it's something I will use daily, or weekly, I want to know everything about it.
If it's my car... That's another story... I've done things that aren’t researchable... But at least others can research and learn from my issues, or triumphs
