SuperDual Twin Pipe Cat-back Exhaust
 From
the clear leader in S4 exhaust systems Milltek brings you the new SuperDual twin
pipe catback exhaust system. Inspired by Milltek's wildly popular RS4 catback
system sold throughout Europe the SuperDual takes S4 exhaust systems to an even
higher level with the greatest value in the industry. A real twin-pipe system
for under $1000 from the leader in Audi aftermarket exhausts? Believe it. Check
out these great benefits:
| 2.25" twin pipes for maximum flow while retaining a
fat torque curve. |
| Reduced size mufflers for increased flow (less
muffler to travel through). |
| Even more power than the standard 3" system (www.AudiWorld.com
rated the 3" system at an addtional 20hp at the wheels!) |
| Aggressive dual 3" tips |
| A more aggressive sound quality than the standard 3"
system, but still well within a level that is fun and not annoying inside
your S4. |
| Takes high-RPM power to a new level. |
| Fully stainless steel, inside AND out. |
| No cuts in the middle of any pipe runs. |
| Installs like an OEM system. Can integrate with Milltek
downpipes and cats if required. |
