There is no such thing as too quiet in our cars. Our cars are LOUD as is.


Maybe I'm just getting old...QQ

I made a thread on another forum about my vette. I named it "midlife crisis-mobile".

I'm not in denial bro.

My plan is to run the big ******* muffler, and if I want more loudness I'll do this with an old TB or something:

Rule of thumb: You'll spend much less money and will be much happier with you're modded car in the long run if you just spend the money to do it right the first time. That's one of the great things about this forum -- learning from others.

And before accusing me of being a "holier than thou" type, consider that I routinely ignore my own advice because I'm so darn cheap (and, yes, end up spending more to fix stuff I cheaped out on).

One of my upcoming fixes (after I swap my diff) is a decent exhaust. It WILL have a Magnaflow.

I did a G8 instead of a Corvette. Had too many 2 seat cars. Plus, it was cheaper.

I find my straight through 3" with the Magna 5x11x22 to still be too loud inside the car. From the outside at the dyno it sounds really good.

Mine passes the wife test, but it's still no stock muffler.

I had planned on getting a plastic bag, filling it full of expanding foam, and placing it under the parcel shelf to see if that helped deaden the sound. I too feel that the car is too loud at certain RPMs. I think it is just the resonant frequency that I dislike, because if I increase the rpm a bit it is very quiet at cruise.

I want a new stingray

I have a cat and a resonator. I have no drone or resonance whatsoever. It could stand to be a little quieter of an exhaust, but it's better than most.

I do as well, but at 2700-3000rpm it's a little loud.

OP, have you checked to ensure your exhaust isn't vibrating against anything under the car. Mine was touching the 5 point harness eye bolt under the car. It made it sound like the exhaust, but once I shortened the bolt the noise was significantly reduced

Brain,
What cat and resonator are you using? I hope to build my exhaust soon and know that I want to follow the well beaten path.....

Yeah, I have a Magnaflow high flow metallic CAT. It still drones a bit too much at around 3000rpm. My noise tolerance is lowering as I age.
