No mate standard apart from K+N induction. Standard exhaust though. If your thinking of remaps i would personally fit an induction intake, corrado 2.9 inlet manifold and throttle body, and a decent exhaust system first - also a 6 branch mani. I rekon you'd be pushing out the horses after that and prob cheaper than buying a shrick.
As standard you will notice a difference with a remap even as much as the drive will be so much smoother etc.
The skies the limit mate, just depends on the dollar.
