I have the scorpion with silenced centre section from scorpion on my 147 GTA.
Like it very much.
Deep, throaty and not too boomy. (Please note the comma in that sentence.
I prefer it's sound to the wizard which is just too loud and lary for me.
The Scorpion exhaust for the V& GT was actually modelled on the V6GT of our own EMAO Regional rep, GT Lewi.
He was also quite impressed with the scorpion.
For the money you pay, the quality is okay, and the sound is something you can live with.
(You will not get folks staring at you calling you all kinds of things under their breath at you roar off at deafening speed)
If you wanna hear the scorpion on my GTA, I am home between xmas and NY, let me know, we can arrange something. Although, you'd have to come to me as GTA is SORN right now.
