thats the job allright

It says in that video that even with the valve shut its still reads 81.5Db at 4500rpm. If the reports are true that the Gardai will be enforcing 80Db then its still not going to help us out.

Also they say in the Video this is set at 50cm from the Exhaust

isnt it going to be a meter from the exhaust here?

Maybe thats the difference...
Either way, Dont act the pri*k and likelyhood of being stung for it are slim.....

 

[forester sti]

What part of the exhaust has a butterfly valve??
Is that just the leggies?
They have some mad exhaust plumbing anyway

LEGACY B4'S 98-03 have it in backbox.

Nothing mad plumbing wise. Twin downpies, centre section and backbox.
