Anyone have any experience with this? I know Berks and F.I. are both very admired, but how about Crawfords??

Does it add a decent amt of volume? How about gains?

Thanks in advance

 

IMO Crawford cats are good..I had them on my car for about a year and a half. I just took them off because my passenger side is messed up..I started to throw a CEL..I dont know the exact code but it was a cat deficiency..I did notice a bit more power in the higher RPM's..U will definitely notice that your exhaust will be louder and more throatier..I have HKS exhaust and HFC's definitely made my exhaust sound even better...

 

When i was shopping HFC i would read complaints that they would crack and break. Like one guy bought one, had them crack, then bought another and that cracked. But there are lemons in all batches and a lot of other people were satisfied. I've didn't see many complaints with FI HFC which is why I got them. Altho the only complaints would be that they are pricey new.

 

i see i see. do you guys have any experience on how these hfc's vary between in each other sound-wise??
