Its the black plastic piece thats right between the mufflers

Does anyone have an idea where i can get the plastic under guard that connects to the bottom of the rear bumper and wraps underneath the car around the fuel tank? Im not sure what this piece is called so searching for it has been difficult. FYI i do live in the states.

If one were to de-flap with a port and polish you wouldn't see much gains on an N/A motor? Are the people raving about this mod mainly doing it for FI benefits? What about these intake mani spacers I hear about? One would think that when doing all these little mods that the power gains could stack u...

im looking at stiffer mounts, lightened crankshaft pulley, exhaust, deleted flaps, port and polish all tied together with a custom tune with a fresh carbon clean of course.

Right on, so for the most power gains through exhaust without losing anything and keeping adequate back pressure would you recommend just the 2.75 catless downpipes with stock catback or just go 2.75 the whole way back? The sound to me is just a bonus, im focusing on squeezing as much power as i can...

Will do once I get her all dolled up and shinning bright. Thanks again.

Thanks a bunch, would you happen to know of anyone in the US thats on par with MRC for that kind of work? Also, are there any issues when going header back large diameter cat-less exhaust, my concern is the back pressure on the NA motor.

So I just purchased my first Audi, a b7 RS4. I came from owning VW's my whole life and frankly . . . . I'm never looking back, this car is just incredible. Now to the topic . . . Has anyone done anything past the usual exhaust, tune stage? Im really curious what these motors can do when built right....
