Default GXP Exhaust or Mufflers??

Hello! I am new to this site but have been following for a long time. I was thinking about putting a Magnaflow exhaust on my 2006 GP GXP, but now idk if i should just put mufflers on. Any suggestions? Possible sound clips?

Best bet is stock exhaust with an electric cutout

Not to take the thread off topic too far, but how do the electric cutouts hold up to winter driving and road salt? Anyone have any experience with this. I want to get a cut out, but was afraid that the salt would corrode it and it would fail.

Magnaflow exhaust with flowmaster mufflers would sound nice. I have a friend who just has flowmasters and it is nice. Though the cold air and ls6 intake made my car sound really mean.

Summit Race Mufflers! They've also broken in nicely and sound better now.

I have 36k on my GXP now, at like 19k I had the Res taken out.

The stock mufflers sound pretty sweet now, still a little quiet but i like it. I do have a set of Dynomax mufflers sitting in my storage room right now waiting to go on..

Catless Hogan DP, no resonator, through the stock mufflers sound like some quiet Flowmasters. I would go with the cutout just because I love the option of going back to completely stock quiet in under a minute. (Manual cutout)

The GXP's tail pipes are nice but suck, when I had my hooker aerochamber mufflers on my GXP without resonator it was quite, when I took off my tail pipes...LOUD,

But here some of my sound clips to prove:

My magnaflow cat-back with stock downpipe and with resonator

This what it sounds like now, magnaflow cat-back without resonator, with 3inch hogan downpipe with highflow cat.

mine went through a winter last year and is on its 2nd and i have no issues....get the DMH cutout because they have a better warranty in case something was to go wrong.
