Recently purchased a 2008 Cadillac CTS4 DI. I love it! As a young adult, I just wished it had more of a growl! A co-worker told me he has a GM Performance Exhaust (Part Number 19165537) sitting his garage because when his wife sold her's, the dealership could not certify it so they replaced it with the stock exhaust. He said it has under 1000 miles on it and said he would take 600$. Anyone have experience with this exhaust? How does it sound? How does it affect HP, MPG, etc. (Pic included because i just love the car.

Maybe he would let you bolt it up so you can see how it fits and sounds in the real world. Agree to a price in writing before you try it and allow it to be returned with no payments if it doesn't work out. Depends on the two individuals and your relationship.

I wonder why the dealer would have a problem certifying the car if it's a GM part?

Agree. Doesn't make sense. Then again, lots of things in this world don't make sense.

It is a full system, just a family friend and co-worker who has had it sitting in his garage for awhile. I asked about the warranty when I went back to the dealership and they said it would not be a problem. I am more interested on the sound and performance of the exhaust.

As a semi-young adult who also recently picked up a CTS also I too am intrigued. :lol: Subbed.

Haven't heard much feedback on it but I am going to buy it from my coworker. Will report back when it is installed.

I did some searching using the part number in your OP and found a sound clip on YouTube from a forum member back in 2009. If I were you, I'd listen to that clip before you pull the trigger. Not sure what you're looking for sound wise, but it doesn't 'do it' for me (especially $600 worth). Do you have a return policy with the seller?

Good Luck, Marv
