What manufacturers make cat-backs for a 09 g37x coupe?
What would be the best sounding exhaust in your opinion?
Which cat-back produces the best power gains?

 

not many at the moment. all of us X guys have had some trouble figuring out what works and what doesnt

i have been bugging ark for a while now lol

i heard the FI works, not 100% sure though

the ExoticSpeed works but they are still in development stages

you could technically buy any exhaust and get the front y-pipe fitted to your car

theres lots of threads about this topic. search around

 

I wish ark would make one already lol

 

Exotixspeed= GREAT,, BTW my car, I have a full write up on here

agreed!!!

 

Supposedly Ark is in the works for one, but by the time its out ill be on to my next car, which may be a 370,

the Invidia Q300 fits as well, i have it on my X Coupe. Supposedly the Gemini wont fit because of the resonators. I actually called Invida and spoke with them about it fitting they were surprised that the Q300 even fit but after sending pictures to them, they believed it. They claim the resonators are the only thing from the Gemini keeping it from fitting but all the other pipes are the same length and size.

also supposedly one person modified a MXP to fit the X. Search around in the exhaust section a bit

 

+1 Im thinkin by the end of the summer

 

they have been saying "just a few months" for the past year

the problem is there are no AWD's in the area, and the dealerships wont lend them one. i am 16hrs away or i would have done it no problem.

 

yeah i feel the same way i would have made a decent road trip and hotel stay for some Ark love but its jus way too far even 16 hours. its a shame montclair wont lend any

 

I just installed Fi traditional catback and resonated hfc's on my x
Sounds is subjective so I dunno what will sound best to you. I like to sound pretty quiet at idle but open up at WOT, so love the sound of my setup. It looks awesome and gets good power. It does drone a bit around 2500k, but I do have a 7at so it's expected somewhat, well see what it will be like when it breaks in a little more.

 

finally someone confirmed the FI fits! thanks!

 

did i hear that correct? is that an X with Fi catback? a coupe? ok im in! the cf one is the same as traditional right?

 

Traditional = oval canisters, CF and SS Round = round canisters.
Round canisters are louder, also there is less clearance from the ground.
I am sure if you want the CF though it will fit the X coupe also, just double check with Tony at FI, he is awesome at walking you thruogh the setup.

This is what the traditional looks like installed. I prefer this look to the round, but many like the round better (or want the louder type).

 

really appreciate the help coolraz... im gunna try getting in contact with him and asking about the fitment

 

do you have the new front x pipe? or the magnaflow x pipe?

i want the CF exhaust, emailed FI yesterday
