Ok so the mod bug has hit me just about a week ago. I have a 2010 G37s in Platinum Graphite and so far I have 8k HID headlight and fog lights, Injen Cold Air intake and I'm Powder Coating my rims a gunmetal black color in the next week or so. Im looking for a set of High Flow Cats but my question is what ones do you guys prefer? I've Heard the Berk on youtube and like it. I'm mostly looking for the more raspy sound so can you guys help me out?

Thanks

 

try what i have on mine car, Exoticspeed

Here

 

Some of the ones off the top of my head

Invidia - 100 cell
Berk, ERZ, Stillen (I think) - 200 cell
Kinetics (i think) - 250 cell
FI - 300 cell
Exoticspeed ??? cell count . . . very pretty . . .

Generally lower cell = more flow = more rasp

 

Very happy with my Berk HFCs... Zero rasp.. Slight hissing sound when downshifting, but the Berks are know for that.

 

Just installed my Berk hfc's today and there is no rasp after warming up. Sounds awesome! Made it louder and deeper for sure.

 

want rasp?? get Test Pipes

 

after watching some videos I think I'm going to go with the AAM Comp Test pipes, but I've read it throws a CEL code on the dash. Anyone know how to fix it so it wont throw the code?

 

programmer ca remove cel code

i need to know which HFO is less cells with good price because vdidia very costly

 

i had the berks too, great flow, added some rasp but i dont like the raspy sound. pm me if your interested in purchasing them. theyre just sitting in my garage in the box now

 

im running berks and love them
