an after market exhaust would probably throw a code too since you remove all the hardware. Don't see what the difference is really. And I'd rather be "childish" than spend 1.5k on an exhaust...

well spending on a good aftermarket exhaust is not childish actually

10,000 miles with the actuator unplugged. No issues.
Took the car in for its first service appointment two days ago. No issues.
Checked the plug after the service appointment. Still unplugged.

How'd mine get unplugged in the first place? I was talking with an SA at a dealership and discussing how I wished my new car sounded "throatier" as I had gotten used to my old WRX with aftermarket turboback exhaust (loud as sin). He replied, "oh, you haven't unplugged the exhaust flapper yet?" and flipped up my trunk, popped the panel, and yanked the cord, buttoned it up and dropped the trunk... all in about 10 seconds while I was anxiously trying to see what he was doing lest anything happen to my new baby.

So... yeah, there may be risks of it throwing codes, but there are certainly dealerships out there who don't care if it's being done (as evidenced by many people not having anything noted or corrected on service visits), and there are dealerships that will apparently do it for you.

Many of us came from other turbo machines. It does not make sense for this to cause any harm or to cause issues with warranty. We'll take our chances.

Guys the Vettes had this as an option on the LS2 to give it an extra 6 HP (430 to 436). Also the Z06 has this exact same setup. I haven't heard any ill effects of driving it open all the time.

My issue...

My issue is not that I want a lounder sound or anything... I'm sure it's not THAT different, but I have this annoying rattling from that exhaust valve and it makes my car sound like shit... so I figure if I disconnect the valve, it won't rattle anymore... I might give it a try today... just worried that the stealership might give me a hard time for the rattling...

If I plug it back in before service, though, they probably can't say anything, right? No evidence of tampering... :shrug:

Ok wow yeah the mod definitely makes a difference in the sound output of the exhaust. It also did successfully stop my valve from rattling.

Exclamation

What does the actuator do ? Is it for take away sound, or for pollution ? Or what ?
