I am getting the Greddy Ti-c exhaust for my 2008 G37. My question is would I be better off getting Berk high flow cats with it or keeping the stock cats and getting a y pipe instead? Thanks everyone!

 

the HFC will make it considerably louder I think... I'm guessing you might need some sort of tune with that also

 

Y pipe wont make it somewhat louder in the mid rpm range (i heard the Ti-c is quite loud, so youll notice a y pipe). HFC will make it much louder than just a y pipe, but together they will for sure make your set up noticably louder.

Honestly, just get all of them, its not really good to go from less restrictive (HFC) to more restrictive (stock y pipe) to less restrictive.

If you dont want the loudness, maybe just a y pipe

 

Thanks for the help guys. I have decided to go ARK performance. That catback is like crack to a crackhead!! I wants it and i needs it! Just looks like such a high quality exhaust and I have learned the hardway that you always get what you pay for. Besides how the hell can you cheap out on an Infiniti for Christ sake!

 

Should go with Berk over Ark. You'll get more than you pay for.

 

Berk are high flow cats, Ark is a cat back exhaust. Two different things. Thanks for your input though.

 

Berk is releasing a cat back in the next few weeks. And you will get what you pay for with it. The Z guys love theirs

 

It won't be in the next few weeks, trust me. If the turn-out is anything like the 370z launch, it will be a while.

 

i would install the new exhaust first - then debate in the HFC - cause i know those will be loud like mine - so you maybe happy without the HFC - just my 2 cents.
