Actually it's the lid on the 2300 that keeps them quiet. I had a Corvette lid on mine and it was pretty loud compared to my 2300 on my 16 with the Camaro lid. TooHighPsi is developing a 2300 billet lid. The Lt4 2300 lid would be great but you can't buy them anymore. I bought the last one that Magnuson had when we did the 2022 Camaro build with the TooHighPsi PI. I was only running 11 psi but it was like 18 psi on the Camaro 2300 lid. The lid is much thinner on the Lt4 2300 lid, plus lighter.
This lid make it whine
or this one will make quiet like church mouse
