Fast Intentions 300 Cell Metallic High Flow Cats *Pictures*
Fast Intentions 300 Cell Metallic High Flow Cats *Pictures*
I've had the HFCs for a little over a week now but I didn't get them installed until last Friday (thanks Yume!).
My initial impression of the HFCs: When I first got the HFCs I was disappointed because I thought they were heavy. But as soon as I compared them to the stock cats I was finally able to appreciate them for their weight. They are much much lighter than the stock cats. I was also very impressed with the top notch welds. Even my friend at Nismo, who is a Crawford HFC fan, said these welds are "hot!"
Installation: The installation was a b!tch. Taking the nuts and bolts off the stock cats broke 2 of Yume's tools (btw, never buy cheap tools..right Anh?)! So we went to Home Depot to get some new/better tools and 3 10" extentions, which turned out to be very useful. To get to the driver side cat we had to take out the intake and a heat shield. This made life much easier. Overall, the install was not too difficult, just very time consuming.
Impression right after the HFCs were installed: I could immediately tell the difference in sound. It is much deeper than before. After a minute or two with the car running, smoke started coming out of my hood and exhaust tips. I freaked out. But after making a couple of calls I found out that this is normal for new HFCs because there are just some things that have to be burned off/away or something. The smoke went away after about 5 minutes or so of continuous revving and driving around. The smell did not last as long as I expected either.
Impressions after a couple days: My exhaust is so much deeper and louder as well. I am starting to feel it pull harder. The "butt-dyno" is very pleased. So far, I have about 250 miles with these HFCs and no CEL yet.
I highly recommend Fast Intentions HFCs to those who are thinking of getting HFCs. Crawfords would be my second choice though.

BTW, I didn't post this in the Review Forum b/c more people check this forum and these HFCs deserve to be looked at
PS - If you guys were me...would you get Impul Skirts or the Injen Super SES exhaust next?

They look to be very quality products. Obviously, we know that Fast Intentions only makes quality products.
Why dont you try first Upgrading your Y-pipes with the stock exhaust and see if you can get anywhere with that before you decide on the catback change.

the only y pipe i would ever buy is the jic one which is about 400 bucks i think
and if i do end up getting a catback (which i wille eventually) it will be difficult to sell it

technically they cant say that they will cause you cant touch your cats for 80k miles so therefore all HFC makers say its for off road use only
Calvin, those look great! LOL, I wouldve liked to see your face when all the white smoke was coming out. It must sound pretty mean with the cutout open.
You have been pretty quick with all the mods lately, why not get the exhaust and skirts? No sways?

do you know how poor i am from all these mods? lol its time to slow down..sort of..lol
right now..im thinking about impul skirts (about $600), then injen super ses ($1k shipped to my door)..but this isnt final yet..still depends on when im getting a new front bumper!
edit: no sways cause i dont need them. its not like i drive the canyons or anything. sways will be something i do last probably. but i will definitely get them eventually.
