08 G37,had it about a month now and the only issue is the rear ex. has a real loud rattle,even when its not running if i tap it it rattles???Whats a good reasonable axle back kit. Infiniti G37 Coupe 08-11 Axle-Back Exhaust | eBay

 

There's actually someone selling an nvidia cat back on the forums here almost new and pretty cheap.

You should check out the classifieds. Im pretty sure there's a few exhausts on there for sale. Oh, and don't worry about buying used in here....most people take really good care of their stuff, sop lease keep it I n mind

 

If your car is still under warranty, you can get a new stock muffler from Infiniti.

 

+1 ^^ if you have warranty get a new one selling then upgrade

 

I got an 08 G37s with a few months of warranty left. I had the muffler, steering wheel, and dash replaced. Muffler rattled on startup, Steering wheel bezel had scratches, dash was peeling on the sides of the instrument cluster.

Do you know the build date on the car?

Great news,called the dealer and talked to the service advisor,looked up the vin and they will do the muffler for me ,warranty just expired by a few months but they are nice and will honer the muffler.still looking for an aftermarket anyway but i will have a good stock one also

 

Nice! Seems like you have a very cool dealership since they didn't have to do that after the warranty expired.

You might like the sound of a new stock one. When I had mine changed a few months ago I noticed that the new muffler sounded pretty nice. It sounds perfect IMO, aggressive yet subtle at the same time.

 

My new stock muffler from november sounded terrible. Had it replaced twice but gave up since there was nothing "wrong" with it but the sound.
