July 26, 201610 yr Hi Has anyone opened up the silencer on an ST (with the rear fuel tank) to replace the packing? I don't mean the end, where you unbolt the plastic tailpipe, but the middle, sealed bit. Thanks
July 27, 201610 yr Flush it out with what cope? Maybe elaborate a little more for people to understand.. I'm pretty sure you told me in a previous post that caustic soda and aluminum do NOT get along , so what do people use do flush the silencer? Cheers
July 28, 201610 yr If you have a `14 the packing should just pull out the back after removing the tip.

I do not have a perfect solution and have not tried the brake fluid thing as it is not known generally as a cleaner, although it will remove many paints. 1- dependent upon year, they were not designed to be re-packed in one or both sections! 2- if they aer screwed, replace them for a best fix and upgrade, possibly. They are crash parts! 3. cutting the things open is not practicle unless you are a expert Tig welder. It seems to me there are two types of fouling in there, oiley residue and hard carbon buildup. Then you get into blown out packing. If it is gone it is gone! Late now, gotta go, will get back later.

The rear section is accessed via removal of the plastic tail pipe. This exposes a perforated steel tube, which is wrapped in sound deadening material. This is only 50% of the silencer. The rest is sealed. Thanks
July 28, 201610 yr Cut it open on the blind side. clean out & repack. It may have stainless wool in the front part. The weld or pop rivet a plate on. Much easier the second time.....
July 28, 201610 yr On a 2014, a good hard run to burn up the remaining oil in the exhaust is all that should be needed. Besides the standard replacing of the packing. You might do more harm than good otherwise. Nothing worse than having midpipe packing slowly coming apart and clogging the rest of the pipe.

A good hard run or series of drag race style runs will get heat INTO THE MUFF AND GET THINGS FLOWING TO EXPEL ACCUMULATED OILEY RESIDUE! It may smoke a bit, that is good, just do not overdo it. CHEAP INSURANCE! Flushing- I would use normal solvents, plug the ends, let them soak/slosh to soften harder residues, repeat. Gas Laquer thinner MEK Might even throw in some ATF in the mix at first because it has good detergent properties.. Air dry completely with a hair drier. Mechanical Cleaning- A stranded wire cable separated on one end and the other put into a drill will run up the inlet perf tube to beat out harder carbon buildup. Full synthetic oil will leave less hard carbon buildup, anything with the good smelling bean oil, the most, as it is not good on low rpm motors. M2C
