depends on the condition of the motor. The better shape it is in, the more you will notice improved power.

The motor has less than a gallon. i was changing the clutch shoes and when I was putting it back together SNAP the crank shaft snapped when I was tightning the pilot shaft.

Yes, considerably.....the stock pipie and manifold is junk. Upgrade to these:

I was suprised to see HPI still have these manifolds, cause no one els did. When you get manifold, take a dremel and widen the header hole to match up with the side exhaust of engine. Measure with paper, then trace onto header bore you start.

Almost any two-chambered, tunned pipe would do, but since I was at HPI' site I chose this one

So the easiest bet would be to just get the HPI A970, which includes the header and pipe(A940 and A950). Doesnt seem too pricy at $59. I would post a link but I guess I dont have enough posts yet.

You will need a coupler between the pipe and header too. Also to answer your original question, you have an RS4-2 RTR. Oh and make sure you get a 2 speed shaft brace. This is not an option to leave out if you are going to add any more power then the stock FE puts out.

Looks like this one on ebay. Fits both your car and the super RS4.
