Just turned 2650 miles and the last couple of days the exhaust rumble is getting louder. I love it.


Just wondering if any else has noticed any difference in their exhaust with more mileage on the car.

I have 4k on mine and haven't noticed any tonal change.

Im looking forward to it... Im only at 1100 miles. My Harley V+H Pipes got much louder and deeper over time.

A lot have commented that it got quieter, which they probably just got use to it. There is no packing to blow out, so there is really no reason for it to get louder, but if you think it is, then cool

I'm guessing that my hearing has improved as mine seems louder now than when new.

Mine didn't change until I had Bullets installed .

Evidently, YMMV.

My daily driver Z51 has gotten more interesting the longer I've had it. I'm sure it never backfired on some of my more aggressive 1st-2nd gear shifts when I first got it. That started happening occasionally after 25K miles or so. Not sure if that's a sign of anything bad, but I like it :-)

A few weeks ago (just shy of 30K miles) I took my wife out and couldn't help but notice the car did sound louder, fuller, and more "angry". Probably no reason for that to occur... but I'm fairly certain the NPP character changed a bit for the better.

Btw I've had my fuse 41 out since 3K miles or so.

Is your car an automatic? If so, the "backfire" you noticed is not a backfire, but a momentary cut off of fuel to facilitate faster shifting (which will occur on all shifts if timed just right at WOT), and is music to our ears!

SoCalC7

Nope. M7. Clearly I'm timing my shifts just right at WOT ;-)

A while ago I read that testosterone levels were linked to driving a Porsche. I just did a web search (click here for some results) and there is a lot of noise that it doesn't have to be a Porsche, thankfully. Fast cars in general, regardless of who pays for the study, tend to increase testosterone levels.

So it seems clear to me that you have now been driving your Corvette long enough that your testosterone level has increased, impressing both your car and possibly your wife, plus making your hearing more sensitive.

I would be checking for an exhaust leak.

SoCalC7

I said it sounds louder, fuller, and more angry... not like ***, lol.

stevebz06

I wasn't kidding. I've had them. Loudness can be objectively measured, but not fullness and angriness. An exhaust leak could actually cause loss of performance and/or mileage and also may be damaging something and possibly poisoning you with CO.

Your car doesn't have enough miles for the mufflers to have rusted out, so a leak is a likely explanation if it really is getting louder.

Are you driving more in tract or sport mode then before?

Casey VP26

Sport mode almost all the time.

I too have noticed that on my 2016 Z51 with 5000 miles. My 08 did the same thing I put 45,000 miles on that one. The longer you have them the better they sound....
