v6 (gta) exhaust options
I've done a search and become slightly over whelmed. My standard gta exhaust has become grotty so I've been looking at a replacement. Upon my search I see there is a lot of choice oit there, as I'm considering changing the manifolds when it's cam belt change time too. From the cat back at least, I like the scorpion for value, the wizard sounds nuts but am unsure how well I could live with it.
Can someone please explain the choice we have from the head back? What's this cf2& 3 all about for instance?
I'm interested to know the noise levels, performance gains and estimated costs for the most popular of systems.
Thanks in advance, and sorry for the newb questions! :-) ed
