Stu Smith Posted May 28 Share Posted May 28 (edited) At what mileage would you expect to be repacking or replacing the exhaust silencer on a 140 Sigma. The use has been a good mix of track and fast road, car now at 19,000 miles. Is there any give away clues on whether the silencer needs replacing or repacking?

Tom_Arundel Posted May 30 Share Posted May 30 I`ve done 40k on track and road and still no problem with the original stuffing. Lots of `Pops and bangs` will shorten its life. You can get it noise tested at a local circuit. Link to comment Share on other sites More sharing options...
