A few months ago I bought my first G35, more specifically a 2007 Infiniti G35 6MT Coupe. It is a great car so far, but I've noticed it is a lot louder than any other G35 I have test driven. I finally decided to see if the previous owners had done something to it and noticed this.
From my research, it appears there use to be a giant muffler behind the exhaust endings, but that has been removed completely. I am fine with this, but my state (Texas) might have problems with it. I am aware Texas requires a muffler on every car (no straight pipe), and while I am missing the back muffler there appears to be another muffler in the center.
So is my car legal? If not, what is the best course of action? I love the sound of my car and I would hate having to undo it, and paying for that...
Thanks.
edit: Also, what did the previous owner do exactly? The lack of symmetry drives me nuts.
That other "muffler" is a resonator and it is there to remove some rasp from the exhaust noise.
I could be wrong but I thought Texas was fairly lenient about exhaust rule enforcement. Technically you are not legal since you said so yourself that you're required to have a muffler. In many states it's technically illegal to modify the exhaust from stock in any way, but almost no states enforce that to the book.
Didn't you get the car inspected when you first bought it? If you did and it passed, I would just keep going back to that same inspection station every year for an inspection sticker.

I didn't get it inspected, the dealership mailed me the tags and handed me the license plate a week after I bought it. I guess the dealership had inspected it, and in that case they probably did ignore the missing the muffler (it was a Infiniti dealership, been around since the early G35s, I am pretty sure they would notice). Would the lack of a muffler negatively effect the emissions test or something else important? If it is just sound, I feel the inspectors wouldn't care as much unless they were super strict.

Lol. Maybe I come off as a ricer to some people, but undoing it would be terribly disappointing to me. I don't think I could do it without being forced to.

The lack of a muffler won't have any impact on your emissions. Mufflers are just there to muffle the sound of the exhaust, and in doing so may add a little back pressure, depending on the muffler design. All of your emissions are handled from the downstream 02 sensors and Catalytic converters forward. Anything rearward of the downstream 02 sensors is there simply for sound control and routing the exhaust so that it dumps to an area that is safe to not make its way back into the cabin while sitting still.
If an Infiniti Dealer sold you the car like that, then I'd go back to them for inspections every year or at least the first year to see how they react to it. If they know you there and remember you, they will probably be more likely to let it slide unless they think they can make some money off of you by trying to get you to install a new exhaust system through them.
