I put Magnaflow Mufflers(don't know model) on my 2003 Deville Base about 2 months ago. The car has 268,000KM, and this is my first mod from stock. I can say it does have a little bit more power but only at the very end of the RPM band.

It only has more growl when I step on it, and has absolutely no drone while cruising which I love. It also saves me about 2 Liters per/100 KM. The mileage improvement might of happened no matter what replacement mufflers I put on, simply because of the high mileage on the stock mufflers, but I'm no car expert.

Exhaust work on these cars are usually for sound, especially the end muffler work.
