I've heard many aftermarket exhausts for the G35 and don't like any one of them. I want to keep the true sound of a G35. Any one know how to make the factory exhaust louder?

high flow cats.

Can u recommend a specific brand and model? How much horse power does it increase? How much louder will it make the exhaust?

muffler delete or Fast Intentions or Craford High Flow Cats

or you can do the HFC

**** you dolphin and whale

Fast Intentions 300cell or Craford HFC. high flow cats will not be as loud as a muffler delete but louder and deeper than stock for sure but not much louder

Do you know what I can get one, URL link? Is this a bolt on job or do I have to bring it to a mechanic?

www.fastIntentions.com

hmmm seems like the site is under construction just give Tony a call and he can help out with any questions, hes a great guy

muffler delete won't really keep the oem sound, though.

fast intentions, hands down.

lol, what?

it's a direct bolt on. fastintentions.com

Go with the HFC like others have been saying.

Crawford, Fast Intetions or Berk are the top 3 that people get. I went with the Kinetix and I'm happy with them.

yea i think FI redid the site or something. you can email tony at info@fastintentions.com. Had mine in a week. Not sure about the exact hp you get but it should give you a little boost. The exhaust sounds deeper and a bit louder. It really gives a growl at 3k+ rpm

wouldn't changing the mid pipe help too?

Changing to an HR y-pipe is nice too. I sometimes miss my hr y-pipe + F.I. hfc combo....
