Looking at this exhaust, it doesnt have a muffler? I have a g37 x sedan AWD, would I have to remove my muffler to install these?

That's their version of a cat back (look at the sku number). That picture is misleading. That's actually for their axle back version which is, essentially, a muffler delete. To install the version you are currently looking at, you'll need to replace the mid pipe and OEM mufflers. It's six bolts total.

 

This is a muffler delete axle back. Its loud

 

1. I just came back from the dealership and they said my catalytic converter is going bad and thats why my check engine light is on, they asked for 1700 so il shop around for a normal priced cc before going for an exhaust. Thanks you.

 

You can usually find members selling them pretty easily.

I'm surprised that isn't covered by the dealership since it's emissions equipment.
