You could piece together a system right now if you want. You can use the GRP catless collectors, y pipe of your choice, Larini sport cat, and exhaust of your choice. There are o2 extenders available as well to get the sensors to the sport cat.

EDIT: Also I would avoid titanium at this point. Lots of horror stories that seem to pop up likely due to the differences in heat transfer/expansion of ti and SS across the system. Its not worth the weight savings if you have to worry about losing your car every track/canyon day.

I've designed an actual dual exhaust, no y-pipe. I already have an Aerie titanium muffler and 3rd cat delete pipe. No problems.

Montana LLC. Though they are cracking down on it I think.

Why can't they just make an option where you pay extra or a special fee for no emissions... that would be the smart thing to do... income for the local government and slightly increased impact on the environment. On the other hand, they could provide increased incentives for going clean energy. That would be a nice balance.

But no.. we have to be 100% one way or 100% the other way with no middle ground.

They won't even let you remove emissions on a car if it's truly turned into a race car and not even registered. Legally they could walk into a race paddock see a production car, do a visual and fine you for removing emissions. They are that much of an ass.
