Anti WHOOO exhaust mod

Worst thing with straight pipes, no cat or modified exhausts is the WHOOO phenomena

that disturbing WHOO you get around 1500 rpm on your V12 and only you inside the car hear

that happens mainly when you remove the middle muffler

here is my MOD with the best sound insolating material currently available
75¨% of the WHOOO is gone

simple, no explanation needed

one roll is exactly enough, keep the bits for under the car to complete; that is behind heat and protection panels anyway

I have full straight pipes and 2 custom mufflers

have fun !

Thanks ! Where are you installing this product ? Inside the passenger compartment Under the carpets ? Or in the trunk spare tire well too?

You aren't installing it outside of the car from underneath the car , are you ?

just unbolt the 9 8mm bolts and you have space
