: Best exhaust option for 2008 cts 3.6 DI performance & luxury package

05-23-13, 01:04 PM
All I am looking to upgrade my exhaust, I have searched and really haven't found what I am inquiring. What are the benefits of going to 2.5 from 2.25 if not force inducted? Also what brand is the best to see a benefit? I would like a nice deep tone, all previous cars I just purchased the mufflers I wanted and installed at a local shop,why install the complete set up from headers back? Any help would be appreciated, didn't use a CAI just went with K&N like I had on my Escalade since it gave me a little more tone and better throttle response, and with the height of this car I don't wanna chance water, in southern Louisiana

I keep looking at the KPE cat back exhaust system for my 2010 CTS 3.6L DI Caddy.
Check out their site, they have a video on their site that lets you hear the exhaust (don't know why every manufacturer doesn't do the same):


I really like the way it sounds with the KPE set up.
Sounds like a small V8 engine.


There's probably 100s of threads about upgrading the exhaust on your Cadillac.
Search the forum and you'll see threads about every after market exhaust out there.

I have a 2010 CTS 3.6L 4door AWD.
I emailed KPE about a year back and asked if their catback would install in my AWD CTS. They replied a
day or two later telling me that it would go in with no modifications.

It sounds too weak for me. I saw that vid a year ago. I want something that is beefy. Deep and semi loud

From other thread

"not my car" This is a video where I got the idea for my set up ,same mufflers "dynomax super turbo's " just 4" flo-pro exhaust tips instead and it sounds amazing my wife even likes it 1st day on and many compliments loud enough to hear but not overwhelming ,deep tone no drone i let off gas and they quiet right up and sound great at idle as they break in there sounding even better i improved gas mileage allready by 2 mpg with city driving only after the computer relearned exhaust flow and all for under $300

Sounds great I just figured out how to post pics lol.. I will try and get video, sounds more like a super car (Ferrari, Gtr,corvette) not to loud just enough as I'm driving it more it auctully starts to sound better the exhaust guy told me it would take a couple if weeks to break in. No disappointments
