How to get that wonderful exhaust sound ??

I upgraded from a C5 Corvette convertible to a new C6 convertible, and find the improvements to be mostly positive, but with one major exception.

The exhaust sound of my prior convertible had a wonderful mellow, gutsy sound, very much like what you would expect from a sports car.

The newer C6 is way less audible, and has no rumble or other noticeable sonic qualities. It actually sounds very much like most of the sedans on the road.

I am not looking for a loud, obnoxious, "look at me" type of noise generator, but I really do miss the mellow and full bodied sound quality of the older C5 factory exhaust.

What if any options do I have? Is a 3rd party exhaust / muffler a huge mistake? Is it very pricey? And am I just asking for trouble with emissions, reliability, etc?

I am unlikely to make any drastic or expensive changes, but I am just curious to know what might be possible.

Thanks in advance to any / all responders.

Put on the NPP exhaust.

Not sure how you got a new C5 that had a wonderful mellow, gutsy sound, as both of mine were fitted with Corsa soon after they got home. Do you know the C5 had a factory exhaust?

Same with the C6, within a month of it being delivered I installed the Corsa Sport. At over $1,000 they are still over priced but good equipment. No need for the cross over pipe as it does little good for sound and it is just more expense. As far as reliability and emissions nothing changes there, just the sound.

I did some research on a couple Corvette forums and learned that a fuse can be removed from the dual system on my C6 which apparently has a pretty dramatic effect on the exhaust sound. I think I will try this first before considering another expense over $1000. I was totally amazed that an exhaust system fuse could even exist, but apparently there is a valve which is computer controlled which opens and closes in the exhaust stream, and this fuse disables the valve, leaving it in the 'louder' position. There are actually YouTube videos showing before and after comparisons.

Thanks again for replies.

Then you have the NPP exhaust. You can get a remote to control it from inside the car whenever you want to change it. Called a Mild to Wild.

The Guys back in the 1960's had the cheapest solution for getting the exhaust sound you wanted : Punch ONE hole in the muffler to get a slight raspy sound. Punch TWO holes to get a mild cam sound. Punch THREE holes to get a 3/4 race cam sound. And punch FOUR holes if you want a definite lopey sound (all without the car shaking at idle too) . Very streetable solution . If you want to go from FOUR holes back to ONE hole, you simply bought a $2.99 box of JB Weld . Your welcome. Glad I could save you some money.

If you can "pull a fuse" and get a better sound you have already paid $1,195 for that option.....NPP. You would already have heard it open up at WOT, but my guess is that you don't have that option or you wouldn't have ask how to get a better sound.

Where in the world did you find a dealer that would sell you a new Corvette without pointing out the NPP exhaust option? Even if it is a

2010 Corvette or just new to you it doesn't have to have the NPP exhaust which wasn't available on the early years of the C6.

Talk about a cheap and effective solution....... I'm not sure I have the balls to start punching holes in my (stainless steel) mufflers. I'm gonna try the fuse approach first, and if that doesn't sound right, maybe I will get out a drill and do a little drilling......

Thanks for the suggestion and thanks to all for your help and replies!!

Yup, if it had the option he'd hear it at start up. Or go take a look at about 8" behind the exhaust tips and he will see the solenoid/valve that operates the exhaust baffle. The damn thing can become tiring at sustained highway speeds imo, which is why the remote control is real nice.

Nah.

I just open a Window and within a few minutes I can hear one of my neighbors drive by with his 'stang. Damn things have become as numerous as horse flies out here.

Smarty;

Tell us more about your C5 and the new C6, does the wonderful mellow, gutsy sound have an accent?

Pretty much the same undercar .. but with more engine options and room for fatter tires in '68

I think true "bloat" was 58 vs 57.

Yep, those 2 new front fenders and headlights made it look like Anna Nicole. It also picked up 51# then picked up 120# the next year with the same design except for the removal of the suspenders and fake louvers(?).

On the other hand when the '68 (3070#) came out it topped the '67 (2960#) by a mere 110#, more than twice the '57/'58 comparison.

Here's a fellows '67 that got the size tires under his C2 that I seldom see on a C3

Nice guy that I've toured with. Enjoy what you have, they're all fun.

All that chrome too - yuck. IMHO The 56/57 was the peak of the C1 design.

65-67 for the C2 with the BB and disk brakes added. 68 and 69 for the C3 is generally agreed as well - before even more bloat and fuel and EPA issues came into play.

I briefly had a '59 and didn't care for it as much as my '68. (Though with a "built" 327 and posi the thing really hauled ass in a straight line.)
