Has anyone put a catback exhaust on their Cadenaz ? I'd like a little more sound from the exhaust but am worried if the ECU would "like" the lower exhaust back pressure of a catback. Any thoughts ?

Hello Beezwax, the exhaust doesn't look all that complicated. I'm
going by a local muffler shop and seeing about doing a dual Magnaflow
or Flowmaster muffler install, maybe getting that deep sounding rumble.

I went to a good local muffler shop yesterday. They gave me a $200.00 quote to install a set of Magnaflow knock-offs (cheaper, made the same), and the installer said he would warrenty them for 2 years. Don't know when I'll be able to get it done, I'll keep you informed.

I got the two knock-off Magnaflow mufflers installed today. Considering you couldn't hear the stock, the Cadenza rocks now! The only time you don't hear the motor now is when you are at steady cruise. At low speeds
and part throttle, the sound is almost booming, almost. It'll take longer to see how well I'm going to live with it, but right now I'm loving it! I was cruising in town and passed a Honda Civic that had "racer" mods, and the poor guy was lookin' around to see the big sound, only to see the Cadenza, boy did he look confused! Don't have any video ability, would be glad to hook up with someone near zip 24486 to make one. Bob

Can we see a video if possible? Your Muffler online link?

I don't know the brand name, but they are basically the same as the smaller oval Magnaflow mufflers. Don't have any video making abilities,
but would hook up with someone close to me to make one to share with the forum.
I had mentioned that the sound at low RPM and part throttle was almost
booming. The factory exhaust is 3-4" from the end of the bumper outlet, so that's how the installer made the new system. I took some exhaust tips and added them on to the new exhaust so the tips are only 1" from the
bumper outlet, the booming sound is now much lower. Overall, I would do it again. Added a K&N factory replacement filter, and the throttle seems more responsive and the car a little quicker from a stop.

Thanks for your reply!

I'm aiming at Varex mufflers LINK

Check this youtube video:

However, I'm not sure what's my stock exhaust pipe inlet and outlet size is? so that I can choose the right product size.

It appears that parts VMK15-250 and VMK10-250 in Xforce website fits on the Cadenza.

Looks like a nice setup. I measured my mufflers that were taken off because they still had pipe left on the intake and exhaust side . The inlet exhaust pipe measured approx. 1 3/4" inside (ID) and 1 7/8 outside (OD).
The outet of the exhaust (tailpipe) was 2" ID and 2 3/16" OD. When the installer put in the system he welded larger pipe on but ends to fit over the stock exhaust. Hope this helps you. Ride On ! Bob

From what you're saying, the Inlet is 2' not 2.5'?

I'm not good at measurements, can you possibly check the photo below, and tell me what you think about the measurements? the distributer is telling me this size fits, but I'm still worried. I don't like much welding or forcing the muffler to fit.

Thanks for the video, the engine start sound is awesome!

Hey iCDoer, the inlet OD on both muffler is 1 7/8" OD, with the driver's side (left) having a flange on it , while the passenger side (right) is a solid pipe all the way up to the front. The short outlet pipes on both sides are a kind of lazy S shape and are 2 1/8" OD. Notice how the outlets make a lot of bending in a short distance. Also notice on the inlet side how the pipes enter the mufflers at sharp angles from the Y joint. This is needed to clear rear suspension parts. I would say you will need to do tight accurate bends and welding.

WOW thank you so much Sir! I truly appreciate it!

I understand much clearer now, hmmm, I guess I have to re-think this, or maybe make a custom muffler.

With a 2.5 OD inlet and outlet it sure needs a lot of accurate welding. :S

I put flowmaster super 44s on mine and dounds bad ***. When it idles low or high rpm sounds really good. I would not rrcommend magnaflows bc they sounded almost stock. Mine costed me 300 for 2 mufflers installed.

I'd agree with you Jake, Flowmasters are quite a bit louder than stock. That's why I use a Magnaflow design, it's just a baffled pipe kind of in a lazy S shape, no restriction. The Magna's aren't as loud as the Flow's, but that's still twice as loud as stock with more of a small V8 sound than a remuffled V6. I'm glad you found the setup that works for ya. Bob
