Are they any good? And btw my g37 sounds like a fart can with testpipes so I just bought the Tanabe Medallion. Good idea?

 

i didnt know they came out with HFC for the G37....they are so so for G35, berk , FI or stillen are good...im using BERK have no issues...

hfc with tanabe should sound dope...do it...get rid of those TP's

 

Yeah I think I got a good PR on the tanabe aswell it was on ebay for 480.

 

I think they sell these on eBay, don't know if they are any good. I would get them, but I don't want to be the one that finds out the fitment sucks and they throw codes.

 

the build on kinetix G35 cats were not good at all...

 

I had Kinetix in my g35, and I went through 2 different Superchargers with the same cat also, and even when I put my car back to stock, the Kinetix Cat still worked like a charm, even until today the new owner is enjoying it. Kinetix is bang for the bucks back then.

 

Here is a good deal on them
