To anyone interested

I believe that is the DNA Motoring catback system. Appears to be a stainless 2.25" pipe that deletes the muffler. It's available on Amazon as well.

DNA Motoring CBE-SIM Stainless Steel Catback Exhaust System

Anyone has one installed? I wonder how loud this is.

I too would love to know what others think of this exhaust. It looks nice but I would love to know what it sounds like.

There are a couple videos of the exhaust on YouTube but I can't post links on here yet

It sounds mild in that video, which is good. I don't want to annoy my neighbors and/or get tired of non-stop rumble myself.

What about emissions testing? Isn't our catalytic converter hidden inside the muffler?

I have this installed. Yes its a DNA motoring exhaust. They call it a catback system but it allows the resonator (scubba tabk) to stay on the car still. This is basically a 2 muffler delete and 2.25in larger piping upgrade. The sound is very mild and sounds similar to a stick 350z/G35 exhaust which I love. The video on yotube actually sounds louder because the recorder is right next to the exhaust. I did feel a slight upgrade to power since the car went from slow to a little bit faster than slow lol. I installed this by putting my passenger side on jacks and squeezed under neath. Because of my lack of space it took longer than it should (1.5 hrs).

Smog should be fine. The catalytic converter is up front right after the headers. The resonator even stays. This exhaust starts from the center of the car after the scubba tank (resonator).

How is the sound inside the car? Any drone on the highway?

You can barely hear it, not annoying at all. Sometimes I wish it was louder but it has a nice natural sound. On the highway its not disruptive. Barely noticeable on the highway.

Did you take a picture of the new exhaust next to the old one? I always like seeing the difference.

350z/g35 sound

Sorry nub question because I couldn't tell from the pic. But did you leave the resonator on to achieve the 350z/G35 sound? or off?

I installed the catback system without messing with anything else in the exhaust system. This entails leaving the scuba tank/resonator on.

Just got this today for mine. Planning on trying to install tomorrow. Is there anything that will pose a headache that I need to be prepared for? Or is it all pretty straightforward?
Can’t wait to have a little sound from it lol

It was straightforward. Oh make sure you don't mix up the gaskets I made a noob mistake and couldn't get the smaller gasket on the bigger flange and had to undo the bolts and take it apart again. Also make sure you lift the car high enough. I have the cheap $20 autozone jack and couldn't get the car high enough on the jack stands so I had a tight squeeze and took 1.5 hours lol. Its a nice sound but its not loud enough for someone who likes loud.

thanks

perf. thanks for the quick response! Can't wait to get this install.

Well it’s on there. You were certainly right about not having much room. I’m going to have to invest in more jack stands because the ground clearance was terrible.

After installing when driving I was noticing I seemed to hear a rattle when I was coming to a complete dead stop and occasionally when taking off. I was hoping it was just the new exhaust needing to be broke in but knowing my luck it needs to be adjusted so I’ll probably have to get back under there.

I don’t suppose you had this affect from your iM did you? I tried to see if I could duplicate it while driving around later on this evening but I couldn’t really get it to do it anymore.

*** Update ***
I work a rotating schedule and today I was working second shift. By the time I got off work it was upper 40° to low 50° and the car was cold. When I first cranked the car and it idled down, I heard the rattling louder than ever. It sounds like it’s coming midway up the exhaust pipe probably close to that heat shield so that’s most likely the culprit.

So does the tailpipe extend more then stock? It seems like the OEM tailpipe is tucked way in and should extend a few more inches to be even with the bumper.

Did you ever find the cause of the rattle?

I believe it was just the heat shield because I bent it a little and (knock on wood) haven’t heard it since.

It does stick out a little bit more, but not too much. Would upload a picture but iPhone dimensions are too large for the size that is allowed in the attachments section.

It sticks out more. It looks stock which is good for police. But tuners with good eyes can tell its aftermarket when you see the mandrell bends and no mufflers.
