It was found out that there is a valve that opens when vtec engages in jdm exhause systems for the dc5r. It was covered in a thread here but i cant find it :/

I think I've also seen the same article. someone on another site bought one and cut it open.
there we go! :D
top speed, 266, on the limiter, completely stock... white knuckle on the freeway top of 6th gear
very scary compared to other heavier cars,
im a mehanic at a ferrari dealership, so we do 300 on the freeway almost every day, since the owners always have jammers and detectors fitted. the wind noise and stability in the dc5 type r was scary!
