I know of only the arj exhaudt but 1400+ tax and shipping is way too much

What other options do I have? What's the best for the money?

Same with coils. I am interested in bc coils but some forum members are saying they are having noise issues in the back. Is there anything better or what is best for the price?

I was gonna go with eibachs but the thought of bring able to slam and raise whenever I want and not bring stuck at a particular height has consumed me.

 

"arj exhaudt". Which exhaust is that??

 

Lol. This guy.

Exhaust options for the X:
-ARK - Sedan 1 / Sedan 2 (Coupe options anyone?)
-Stillen - Link
-Tanabe - Maybe?

Exhaust options (General):

-Invidia
-Tanabe
-Fujitsobo
-Meghan
-Stillen
-Fast Intentions
-Ark
-HKS
-Greddy
-Borla
-Magnaflow

All of the above are Cat-back, which won't produce any significant performance gains, it's mostly just for sound. The first three on my list are generally quieter, and the latter two are pretty deep and loud. Ark and HKS also have similar sound, at least in my opinion. Go to youtube and search out each manufacturer with G37 and you'll get an idea. Other options include changing out your cats for High-Flow Catalytic Converters. This will increase performance.

Options for new cats include:
-Berk
-Fast Intentions

As for the Coils, I can't help you there. Now that you've got some information, search through the forums, as there's a lot of really good stuff on these topics already.

 

Pretty sure not all of those fit the X...

 

In fact I think only ARK in that list has an X model...





Correct me if I'm wrong.

 

If you don't want to spend $1400 bucks then just get an axle back or just keep your stock one.

 

I love my Fujitsubo/Infiniti Sports exhaust

 

Good catch, Tim, thanks. I didn't see 'for the x' in his title until I came back to this post. My bad.

 

so the one for the x would be the only one? i was writing this on my phone last night and my autocorrect is kinda messed up. sometimes it works sometimes it doesnt and sometimes it just puts random words

will all the axle backs fit on the x?

 

Axle backs may...

Not 100%.

 

All axlebacks will fit with at most minor adjustment of exhaust hanger arm, nothing to get in the way. There aren't that many axleback options though.

Tanabe, Infiniti/Fujitsubo Sport or Legalis, Megan, hmm don't know what else.

 

I have Fast Intentions on my X coupe and love it! Paired with their Resonated Test Pipes.
