Hey guys, please help me, I need to find out if a magnaflow exhausts will make weird noses when the engine goes to v4 mode. Can anyone confirm this please? thanks.

I honestly don't know, BUT, the cat supresses a lot of the exhaust noise on its own. A buddy of mine, after receiving a new cat back for his Holden/GTO removed the stock exhaust behind the CAT. Prior to installing the aftermarket, we took it for a spin (HAD to do it)

 

Now, it was loud, but not as loud as I expected... I guess the cat is kind of a mufler on its own....

 

I am thinking it wouldn't make that much wierd a noise, but, AS SAID, don't honestly know.

Magnaflow doesn't make a kit for my truck yet so I have used the following models: 12279, 12388 (35111 tips). The 12279 in V4 mode was more pronounced than the 12388. It isn't bad just a lower pitch (almost like an upshift) and I only notice it at highway speeds at 70mph if I have the radio off, otherwise I never notice. A shorter muffler would provide a louder exhaust but I just wanted something that sounded more like a truck. Pretty mellow most of the time and sounds really good when first cranked in the morning. No drone, but you can tell when V4 kicks in if you have the radio off and are listening for the sound. I bought the muffler(and tips) off ebay from Performance Curve. You can make an offer and they ship for free.

I have the 14218 and it has no discernable drone. It can be heard in the cab and has a different tone when it goes into V4 mode but its not obnoxious. It sounds like the V8 cut in half. I don't think you have to worry about it sounding like a riceburner.
