What up fellas! I'm lookin to order a pair of HFC's. I'm thinking maybe Stilled, Crawford, or FI. Any others I should consider? I wanna keep the stock exhaust tone but louder. Thanks!

 

Not that HFC will do you any good with the OEM exhaust but Fast Intentions
are the ones I'd buy.

 

Fast Intentions 300cell Metallic HFC

 

+2 for FI high flow cats

I have the 300 cell metallics and i love them.

I believe Stillen cats are nothing more than renamed Random Tech cats, which don't have a great reputation from the reviews I've rear.

You can't go wrong with FI or Crawfordz.

 

Berk Technologies because their stuff looks top notch and they utilize the stock tranny mounting brackets. FI doesn't do that and I see a major problem with that.

 

FI 300 Cell Metallic Cats FTMFW!

Its what I have on my car and I love it!

 

Are there any good HFC with stock mounting brackets? It looks like FI does not have this, but it's still one of the best.

 

Not any good performance wise or sound wise?

 

O RLY- In that thread what cutout were you talking about that was open?

 

Could someone elaborate on the FI HFC mounting issue? I'm getting a set soon and would like to be well informed. Thanks

those are double the price of FI!

 

SRSLY... I guess if money is no object, go for it

 

yah, I guess you're right. I'd probably do the same thing.
