Dear Ralph:
My dealer told me that when I buy a set of aftermarket pipes to make sure that they have rebuildable silencers. Why is this an advantage over the non-rebuildable types ?
If the silencer has a “fiber-pack” it will burn out after about 2000 miles (or in a few years). When this happens the pipe will get a bit louder and you could loose some of the back-pressure that might result in a decrease in performance. Think of it like shocks. If what’s inside goes bad the rebuildable unit allows you to fix it instead of buying a new one. If you go for the non-rebuildable silencer, find out how long it is expected to last.
