NEW Pro Circuit T-4 quier core

[2001-400ex'er]

I was wondering if Pro Circuit came out with their new T-4 quiet core cuz i heard the old one was junk, if not i think i will just get an HMF with a quiet core.thanks

Well I got one for mine but it makes it sound like chit so I took it back off. Plus, they said if you constantly use it then you must replace it every 30 days. Screw that. Just let her roar.

i used to have one....i bought the quiet core and it sounded like chit....i took it and drilled 8 holes in the washer and it quieted it down and i think it made it sound better
