Packing in 335i exhaust vs PE exhaust

mweisdorfer · 01-16-2017, 08:26 AM

Does anyone know if there is a difference between the packing or insulation used in the 335 exhaust vs the packing used in the PE exhaust?

If so, what insulation do they use? Is there a comparable insulation you could buy and replace it when you do a PE mod?

99% of the sound from the PE mod is the fact that your putting in straight through pipes. I doubt there is much if any difference in the packing used.

the packing will help get some of the drone and unwanted frequencies from the exhaust note.

if you are performing PE Mod, use the same insulation.
