It has been 6 weeks since I ordered and I finally got it!
It is amazing even stock, sounds great at anything beyond 3000rpm. Makes me feel like a hoon in fact even when driving normally.
You always know that you have 6 litres of V8 fury under the hood, ALWAYS!
Otherwise, very very smooth and solid ride on the freeway and the interior is actually a nice place to be. Good job Holden !
