R300 noise levels

[jabbers]

Hi guys,

 

Loving the noise of my R300 but think i really do need to quiten it down, ☹️ booked on the clubs trackday in Oct at Oulton Park, but worried about the noise testing, car currently has 4-1 exhaust with de-cat pipe, do still have the cat in the garage though, would it make a big difference and pass the 105db with the cat on or do i need to be purchasing a silencer ??

 

Thanks

Mark

Mark I'm not really familiar with the R300 silencer, but is yours repackable? ...if so that might be the answer?

 

ISTR from reading on here that the cat may not reduce the noise much.

Also if on roller barrels air box may help quieten it down

 

My R400 (k) measured 100db dead at bedford 4500revs with a repacked exhaust 😬

R3/4/500 silencer is re-packable.

 

Assuming it has sufficient filling in it getting under 105db will not be a problem so just enjoy the noise.

Standard R3/4/500 exhaust is 4:1 via a cat or cat by-pass pipe to a short silencer. The silencer has 6 dome headed allen bolts on the front flange. If yours looks like the description you have the standard exhaust from that period which is re-packable.

 

To re-pack it take the silencer off, clamp at the front and bobbin on the rear bracket. Then take out the 6 dome headed bolts mentioned earlier and the outer sleeve can be taken off complete with the front flange.

Adrian, it is re-packable then as exhaust has those bolts, thanks for your help and patience 😬
