ballance pipe and db measurements

[450r.net]

what db does the ballance rate at? if its not passing will you have a quite core for it, i really like the pipe but plan on running some gncc and would like to keep it, i figured since it was a pipe for a gncc racer it should pass, but was just wanting to hear from you guys

The pipe runs at about 104-105dbs and with the quiet core installed it brings it down to about 96-97dbs. Hope that helps.

did it come with a quite core? im running the tube insert, i thought it was a torque modifier, was their i quiet core as well?

The quiet core is completely different then the torque range modifier that you have . You can purchase the quiet core seperately for $20.
