Hey guys,

I am thinking about changing my non-NPP exhaust out for something a little different. I want it to still be tame at idle and when cruising, but want it a little bit deeper.

I don't really want to spend over a grand on a new exhaust, so I was thinking about replacing the muffler with a magnaflow or dynomax, etc. Also, I do not want any drone, so dynomax bullets are out of the equation.

I know I need 2.5" in/ 2.5" out, offset, but what size would be best? I couldn't find much on youtube, but any sound or video clips would be great.

Thanks and have a safe and happy Memorial Day. God Bless our military.

Have you had NPP exhaust before? Or do you not want it? On my last C6 I had non-NPP and switched to SLP Loudmouth 1's. It was noticeably louder but still pretty tame for a straight through. On my current C6 I have the NPP and couldn't be happier. With mild to wild its loud when I want and super quiet when I want. Best of both worlds. There's a clip in that thread. Granted it's with LT's and X pipe but you get a feel for how different the two modes are.

I just replaced the stock muffler on my 2006 Vert with a used NPP off a 2008 Coupe. I got the muffler for about $500 or so, another $175 for the mild to wild controller kit and then a couple of hundred to install everything. I'm under $1,000 all in.

The only reason my install was so high is that running the vacuum line to the controller took longer than expected.

The actual muffler install is a snap. It's a bolt-on if you go with the OEM NPP muffler and you just lower that rear sway bar. But if you go used, make sure you get it off a C6 non-Z because I think the pipes are different size. Not sure, though

Now as for sound, the controller makes it quiet if you want. The only way to describe the sound when it's loud is that it is very American muscle-like. No drone to speak of.

Under throttle at the loud setting, it's bad-azzz.

And while there is no horsepower increase to speak of, you think the car is stronger off the line or when you floor it when you have it set to loud because there is an automatic auditory response that you can hear when you hit the accelerator. Your mind associates the sound with the increase in speed and it's a great feeling.

NPP or used Corsa Sports will do the trick

I have thought about NPP, but wanted to see about replacing the mufflers first. If that doesn't work out I will go the NPP route.

Does Magnaflow have any drone to it on the highway? Im talking about their regular mufflers, not the magnapacks.

check the SLP Powerflo

Just go NPP to start with, save money and time... They all drone that sound great... with NPP you can have it both ways... love mine.

#14336 Magnaflow mufflers fit. But doing the swap is expensive, you have to buy the mufflers (and tips unless you weld your old tips to the new mufflers) and pay someone to cut and weld the axleback piping. You'll be very unpleasantly surprised at how expensive mufflers and tips are.

You will have drone.

Your best buy is a used Z06 complete exhaust, next best a used NPP if you want sound without drone.

so magnaflows drone as well?

Changing mufflers to something more aggressive is going to get you some kind of drone. Of course, drone is a very subjective perception. Just be aware.

Magnaflows on 07 and never a drone!
