No pressure!
I was a little bummed when I read that too. It's contrary to other reports that I've read but I'll do the best I can to provide a good write-up. I'll see what I can do about providing sound or video clips as well.

This guy here even swapped out his non-Resonated BERK's for the FI RHFC. Love his video comparison.

I get the sense that most people in this forum modify the exhaust for sound as a priority, in which case you could go axle-back and be done with it. Seems to me, though, that efficiency gains are at the headers, not behind the axle. So that's where I'd rather start. And start with FI's resonated cats to future-proof the rasp out of whatever cat-back I eventually get.
I'm guessing that's where your head is at on this, too.
I'm also guessing/hoping you're going to love the new cats, both in sound and grunt.

Those other reports were likely about having a traditional, non-resonated HFC with the OEM cat-back. I've not run across anyone who put Fast Intentions' resonated HFC on first, before upgrading the remaining cat-back. Well, except for that Alfredo cat, and he was unimpressed.

But now with the Invidia Q300 with the upgraded X pipe I'm sure it is going to matter
and I just can't wait till Wednesday to see the results of the Berk HFCs together with the Invidia CBE and I'll have it like for a while and then try to decide If I'm happy with berks or whether FI RHFCs would be necessary lol.

That could be. I'm interested to see what your thoughts are down the line a little bit. I suppose I am expecting a subtle but marked difference.
So you're the guy who snagged that awesome looking one of a kind trunk! I had eyes all over that thing back when Alex put it up for sale in the summer, it was already painted moonlight white and everything 
I'm really liking what you've done with the car so far, those blue demon eyes are mean looking! I'm excited to see what you'll do next, and at the rate you're going it doesn't look like I'll have to wait long to find out
Happy modding!

Happy modding!I'm loving the trunk, all the work they did at 180 was excellent. It's coming together nicely (I think) especially for a car I wasn't going to mod...

Things are slowly coming together. FI RHFCs arrived today and I'm really happy with what I see of them so far. New spare tire also arrived, that was a lot to juggle down three flights and back up a flight to where I parked. Rims arrived at the powder coater, should be ready when I get back from Buffalo and Toronto so.... I'm looking for a little feedback please and didn't want to annoy just Brad with this question for... Probably the third time, though with a slightly different variation.
I've decided to run a squared set up instead of staggered and will be running Rays forged G35 coupe rims which are 19x8.5 with an offset of +33mm to the best of my knowledge. I'm thinking 245/40/19 all around. Comments / criticism / other suggestions?
Other than that I've been collecting parts. Cusco bar is on the way, sways will probably be ordered tomorrow. Couple other odds and ends for when I have time and weather to tinker and am looking at some things under the hood now (I may have too many logos).

We don't get a lot of snow in Memphis though some of our roads ice up due to poor engineering, well more than they normally would I suppose. I don't think I need true winter tires here so I think this will be a decent compromise.
Thank you Brad! I'm thinking the A/S3, anything else you would suggest?

For All seasons again, the Michelins get great reviews and I've been happy w/ my Toyo Proxes4 Plus. If you look into the Toyos Treadepot has nice deals, talk w/ Andrew & mention the site for best prices.
