3" Exhaust Mods for AU3 XR8 - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have just got my AU3 XR8 upgraded to a 3" system. BLOODY BRILLIANT!! :s2: :s2: :s2:

Brilliant sound. Just what I wanted. The engineer found that it "boomed" too much with the normal small resonator he uses on 5.7l engines, so he fitted a Kobi resonator and all is sweet.

Here is the Dyno graph of the results.

Here are the shots of the exhaust.

No, I decided to not get the extractors at this stage. Kept the price down for now.

Nice 'n clean! :s2:

Yeah, we still have the standard extractors too.

Any other mods planned?

It's a custom job by Torque Performance here in Auckland. Built as a result of years of experience with the Windsor engine and what different customers want out of an exhaust upgrade basically.
