need to loose some DB's... help

[Tilly819]

ok folks

borrowed a db meter from work today to check noise for IVA

as i gather it needs to be 99DB or less at 75% of full engine power so for me that 7500 RPM sounds dificult alredy dosnt it

ok my problem is im getting about 117 DBs at the required distance and angle.

i think some of it is engine noise not exhaust noise so any ideas of a cheep is way to sound deaden my engine bay dont fancy they expencive matting at 60 quid a meter

also any ideas on how to drop the alcual exhaust noise i was thinking maybe stuffing it with wire wool?????

all sujestions would be great...

chears tilly

ps went for a quick drive round the block tonight only at about 30mph but felt good
