After last rally, held 14th may, exhaust mufler was totally broken by stone shoots. As a “do it yourself” solution, I find an old muffler in good shape. The question was just, if its quiet enough to match those noise regulations in rally. Because of that I decided to “Pimp my ride” a lit bit. One of my co-operation partners is a local recycling company. I made a short wonderland trip to their field and finally found an old stainless steel coffee thermos bottle. By using that outside and inside a perforated tube from old muffler I welded a nice endmufler.
Recycled and opened Stainless steel coffeethermosbottle.
Inside pipe from 9000 Turbo muffler and outside thermosbottle.
Looks good, and sounds better. Rebuild costs nearly nothing.
Test drive was directly after rebuild in one local small rally, Imatran-ralli, held 27th August 2011. Totally 35km SS it was good practise before bigger events. Because of small organisation, there wasn´t any noise measuring, so it´s still unknown how “good” db-values we have now. The rally itself was good for us, and without any problem we managed to drive podium in first place overall between all Historic cars.
