You can basically install "any" exhaust that you want...
what are you after?
2.5" 3"...
cat back?
manifolds back?
it's all out there...
get what you want and have a professional exhaust tuner ship install it for you....
my exhaust on my 01 2.5 RS is made for a 00 Turbo.... (UK)
but i had a custom center pipe and exhaust hangers fabbed...
and it fits, works and is awesome...
hope this helps...
cheers
