Exhaust question

[nick11]

Just bought an 05 CC,4X4, 6.0 auto and the exhaust ie rusted so I would like to replace it. Is there an exaust that is not much louder than stock? Can I change exuast only with a tuner or intake change? I am not looking for more power, just better looks and MPG if possible.

What ever you do to free up the flow, it will be much louder.
With an intake you will hear more turbo noise on the intake side.
The tuner will not change the exhaust noise on a stock exhaust. Maybe a little if it has a straight pipe.

Getting delete pipes, cat back, or turbo back will help you regardless of tuning.

Skip cat delete and go for tubo back. Had all of the above spent more money than needeed to.. Sounds great a little loud around 3 grand but puts a smile on your face everytime. As for fuel gains maybe 1 mpg if you can keep you foot out of it. Go for ficm for fuel gains. I do have stock cat delete pipe if you want it?
