I want to upgrade the exhaust and let the car run and sound at its' true potential. I ordered the Corsa setup for around $2,200. Paid for it. Was supposed to be here today. Great! Turns out, they don't make the Corsa for Deville DTS anymore, they don't even have the design plans for it apparently, "according to them". So, my question to everyone here, what can I get for a full setup that's decent quality? I want it to be louder than stock, that's for sure. I'm looking for suggestions. Also, we looked into the STS Corsa and it "doesn't work" because it's "shorter in some areas".

 

Save yourself a pile of money and put Chambered or Straight pipes in place of the stock mufflers. You could also use cherry bombs which are more or less Chambered but please paint them hi heat black prior to installing.
