Audi B7 RS4 ECS H-Pipe Kit
Here's a "sound" investment that will give your Audi RS4 a voice worth listening to. ECS Tuning has developed an H-Pipe that replaces the OE resonator, producing a great outside exhaust note that won't drone you out of the interior.
As an added bonus, we've personally tested this H-Pipe numerous times on the dyno and found an extra 3-5 hp at 6000-8000 rpm. The H-pipe won't interfere with flapper valves in the rear mufflers.
Installation is a cut and clamp affair. Cut out the old resonator; clamp in the H-pipe.
A Sound Investment.
