That HMF db number is at idle, not wide open. The stocker at WOT is like 120. I know because I had a db meter.

oh crud, then can anyone suggest a pipe with very similar gains with less noise?

i think the park rangers here would have a shat fit over 120db...or do parks only measure your DBs at idle?

theres no way a stocker can me 120DB theres no way.....then i guess my tc is like 200 cause the tc makes an hmf almost sound like a stocker.
