Hey Guys...when putting the car together i picked up a second hand GTI exhaust with the dual downpipes, although, i'm still running the factory exhaust manifold...however it wasn't in the best condition to start with and I think after doing a couple track days it is starting to bite the bullet...

I guess what I'm wondering is if I'm going to replace the exhaust, are extractors worth buying? Can I expect any real improvements or noticeable differences in performance or fuel consumption?

Michael.
