Another side project I had meant to do for a while was to repack my silencer. Often on track I was pushing the noise limits, especially Bedford where I have to lift past every single microphone, super annoying so it definitely needed doing.
In hindsight, perhaps it could have waited until the rear clam was off for the conversion, much easier job then but I wanted it done before a trackday to give it a good thrashing to settle down the new packing.
Bit of a tricky job on your own with the rear clam on, bit of balancing on a jack to undo both fixings into the ally boot floor, but manageable.
I’d researched online at other people’s threads about how to go about cutting and what end to cut. Seemed straight forward so got the hack saw out and hacked away… turns out my silencer seemed to be backwards to other people’s and the whole inner baffle came out too. This made getting the acousta-fil in and everything back together much harder than I’d hoped.
The state of the old baffle, definitely time for some new stuff.
Another issue I had was getting the two apart. With the limited tools I have at home I was able to borrow a mini racket, strapped it to a tree and yanked and pulled and twisted for ages to get them apart. A combination of brute force and a few large flat-heads (being careful not to bend the thin metal of the silencer) got the two pieces apart. A vice would have been much easier.
I had planned to cut the side that would leave the baffle secured inside, meaning it would be fairly easy to slide the new acousta-fil down and then just pop the other end back on. Instead had to wrap the acousta-fil as tightly as I could around the baffle and try to slide it down into the silencer without it catching on anything. On top of that, it kept getting stuck on the ring the baffle slides into at the bottom of the silencer casing, leaving me no way to reach down inside and tuck it out the way. Unfortunately i had to cut it the acousta-fil shorter than I initially wanted to avoid this.
It then took a lot of hammering and twisting to get the two pieces together, but after lining it up with the marks I’d scratched into the silencer before cutting to ensure the mounting brackets would all line up, it was ready to be welded.
Unfortunately the welder I used was pretty shoddy, fairly expensive and took AGES but thankfully did the job, if not the prettiest weld in the world. Next was the fiddly task getting it back onto the car with the clam on, but after a bit of fiddling it was all bolted up and ready for the trackday, which went well…
Snapped rear upright bolts threw me straight off, thankfully not into any barriers. No other damage, just one of those things you accept, fix and move on.
