This is the sound I'm after https://www.youtube.com/watch?v=igyp...&nohtml5=False

would a Thumpr produce this or does this call for a Mutha Thumpr ?

If it's a Mutha Thumpr, I'm guessing you meant 11-601-8 ? the 01-601-8 is for a Mk VI and mine is a Mk IV big block

I live in Sri Lanka where the ambient temperature is 98 to 108 degrees Fahrenheit. (37 to 42 Centigrade)

Would I benefit from the air gap intake ?
