: 98 Deville Concours Preformance Exhaust???

I really want to get a new exhaust to increase my Horses and mostly just to improve the sound! Does anyone know where I can find a website or anything to help me? I cannot find a thing on the stupid subject!

No real horsepower gains, no aftermarket packages for pre-2000, so head to your local exhaust shop and have them mandrel bend up a 3" cat-back (keep a resonator or the drone will run you out of the car) with a good, smooth Y into two Magnaflows. You have a car for which there is practically NO meaningful way to extract more HP. Do a lot of homework in here and up in Deville ^^^.
