I've had my 2008 G35xS for a few months. I've added wheel spacers, gloss black wheels, and yellow brake calipers. Trying to do something bigger though, looking for a new exhaust system, preferably between $1,000 and $1,500. I've heard the stillen cat-back isn't to bad, looking for a deeper noise. Any suggestions for the exhaust? Also trying to put on a CAI, duck bill on the back, and maybe a plenum spacer with a MREV 2 manifold. P.S. first picture is with the black wheels no spacers or calipers, the second is when I first got it.

 

You really can't go wrong with Fast Intentions. I have a FI catback and resonated test pipes on my g35c and it's soooo good.

 

You have a different engine, wouldn't be using the spacers or mrev2 on a VQ35HR

 

 

That's a huge load of bullshit lol, the engine compartment is still hot and for some (not necessarily this vehicle) the intact tract can be a source of restriction.

"Cold air intake" just means it draws air from somewhere at the front of the vehicle and not from the engine compartment, the stock HR intake is technically a cold air intake but some of the aftermarket ones perform VERY well on that motor.

 

I'm looking at a top speed pro 1 cat-back exhaust and it says it fits my year and engine but the end of the title says rwd. I mentioned earlier that I have a G35xS 08, so it's awd. Does that matter on Infiniti sedans, I know sometimes it matters and sometimes it doesn't.
