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.

Yes you're correct i remember now. It had pics and all! very interesting.

It actually opened a valve which allowed the exhaust gasses to pass through the muffler freely without being restricted (correct me if im wrong).

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!
