I'm sure plenty of people have annoyed you all with questions like this but I am a new owner of an 07 G35S. I have made a few visual modifications to it but I am really wanting to get rid of my stock exhaust and intake. I am also looking to drop it about an inch. Price is a slight issue but please just give me some advice on good quality parts and I will figure out a way to make the price work. Again, I am very new to all of this so I need all the help I can get!

 

Nice first post.

My suggestion: Search.

 

Nice sig

 

I lol'd at that too.

 

I've done some searching as far as exhaust, intake, and springs go. I've found a couple things.
Exhaust: Borla or Stillen seems to be most recommended
Intake: K&N cold air, Fujita, Injen etc.
Springs: only really heard about Eibach pro kit

Any opinions on these?

 

HKS exhaust!

 

What kind of sound could I expect from HKS? Im looking for a deeper growl, good idle, and good acceleration. So basically Im looking for an all around agressive sound!

 

I'd go with the Injen intakes. They look nice and provide decent gains on the HR. As far as exhaust, I'm not very knowledgeable with V36 sedan exhausts.

 

The Hks has all of that. Roars when you get on it and has an unique sound. Should go search up videos to determine which setup you want.

 

Another good one is fast intentions

 

^+1 FI for a nice refined sound and stillen if you like a but louder sound

 

Thank you for all the suggestions. Does anyone know a price range off the top of their head? If not I have no problem looking it all up.

Also, how much if any will the sound be affected if i only go with mufflers instead of the whole catback system?

 

Since you are only looking for a slight drop I'd go for the Eibach Pro Kit. I think Tanabe's would also work for you. Exhaust like everyone here said, FI or Stillen or you could go custom. Personally not sure about intakes, some people have noticed some gains with Injen and Stillen Gen 3s though. I have K & N drop ins, it suits my needs, lol. Good luck though and let us know which route you go and how it all works out for you.

 

Here is Fast Intention for you

I would recommend injen CAI, Invidia CBE, Fast Intentions HFC's Tein H-techs for a mild but comfortable drop and get it tuned! about 500 bucks for intakes, 900 for exhaust, 550 for HFC's, 600 for the tune and like 300 for the springs. get some F/R sway bars and a strut bar and then you will basically have what everyone on this forum has! you can expect 270-290 WHP after those mods. Also the first thing you should do is put royal purple synthetic oil in your car along with 93 octane! just my
.02. let me know if i can help out in any other way! thanks
