So , 749 silencer now cut and open , that was fun !! Tubing ordered so whilst it’s coming a couple of questions. I am leaving the cats in the pipe/silencer , theory being it may keep some back pressure and not affect ecu fueling hopefully . And not give full loudness The plan is to use the wire wool and stranded stuff but add more to fill missing metal . Do I pack this tight or loose? Does tight quieten things or make noise Any recommendations of wadding
Bugger the filler used expands and doesn’t require mesh as it matting not strands , that’s what they told me ??
Was hoping by keeping the cats it will keep the noise down , heat I hope will be reduced by the increase in flow under the seat
Now back and looking ok , now weighs 6-3kg , what’s a standard one weigh? Think I’ll fit after I have booked the mot
