Hi all, recently bought a 2008 QP GTS and just back from a 3,000 mile Alpine road test.
The car is fantastic although I would prefer a little more roar in the cabin, especially with the
windows up (Its cold up north).
I'm favouring buying some 4.7 gts back boxes, it appears they will fit but has anyone actually done this mod?
How did they sound with the 4.2 engine?
Any advise would be appreciated.
Cheers
Alfie
