I'm assuming it isn't so my follow-up question is, How legal is it to install an exhaust system that can become illegal at the flick of a switch from inside the cabin? Basically dumps from the sound of their description when its in open mode. Part of the answer to this question really depends on the level of risk you're willing to take.
A a flow-chart diagram of their system can be found here. http://www.kreissieg-usa.com/?_page=10&gubun=f1
Thanks for that ^ |
The website's portrayal of the exhausts for the E60 and the E46 appear to be CAT back and therefore would potentially be street-legal, assuming no violations of local laws restricting db levels...
I'm interested in how the weight of the
Valvetronic compares to stock...
I'd also still like to see a pic of the actual piping especially how it looks with the bends/transition at the "CAT bypass" area...
