After reading just about all that's current about the above, I'm more confused as ever. My goal is to switch out the OEM system (too hollow sounding) to something perhaps deeper with more resonance without getting any louder. The ARK Grip sounds like it could be a little loud and am leaning toward the Fast Intentions system. Any suggestions? Many thanks.

 

I think Invidia will fit and it's not that loud. Please do a context search to confirm. I think another member did this so the post is out there somewhere.

 

try doing a custom exhaust,
If you don't want to go too loud go with ark burnt tips

 

Ark is the only one that someone has installed successfully and posted pics (that I know of).

 

Are you looking for cat back or axel back. The Sports Exhaust really is nice sounding as well while keeping the b-pipes.

 

Do you mean the "sport muffler" that Infiniti offers? Yes, I have considered that. And whether it's cat back or axel back, it doesn't matter. Cat back will increase power some, but can also be louder. Also, I'm familiar with the ARK
installation ... which is a great idea, but could be too loud for me.

 

More effort than it's worth to do that.

Here you can compare the stock vs the sport accessory one. This is different than the IPL one.

 

The Fast Intentions coupe exhaust will not work unless modifed for the vert (just pass the axle). Not sure if that was noted before. I poke to Tony at Fast Intentions at ZDayz and this was confirmed.

 

There's a new group buy for the Fast intentions CBE. Get your name on that badboy.

 

We need 10 names to get the build started. Only myself and one other so far.
