They go through your engine bay. Wen I picked mine up there was also a diagram of my exhaust.

Yeah I went through the sound issue with my old SS, the diagram they draw is stored & if your caught again with the exhaust different to what's on the diagram your in big trouble $$$

Sooo essentially everyone's modded cars are illegal?!??! Is this just nazi states or everywhere?

[LAZY6]

Think it's everywhere unless engineered.

Correct me if I'm wrong but is it two mods your allowed legally?

Only if those "mods" are deemed legal.

So how come the cops don't just sit across the road from every tune house in the country and bag themselves a tonne of fines? Until everyone realises and they all go out of business.

Doesn't make sense. Surely there's a point where the emissions are too much but surely there's plenty of room. Then what about e85, that would have to balance it out, even maybe below stock.

Oh ok cool. I wasn't too sure. I always thought it was something like 2 intake type mods (cooler & cold air) were acceptable, anything further & it's a no no.

WTF is the small dot in the lower grille on them?...

Radar for the cruise control. It will automatically slow down if traffic in front is going slower

Back to real topic though as others have said I would be working closely with your tunner

In theory if you can prove stock or better tail pipe emissions under all conditions then it should not matter what mods you have but the reality is the authority doesn't know how to really manage thus so they make blanket statement like no mods to fuel delivery system. Ie injectors

All depends how much work you want to out into fighting it

There's a reason nizpro are the only ADR and EPA approved kits.

[Paulie2256]

Yeah but you don't get the tune the kit was approved with. Otherwise it would be a generic tune.

[Mr_4.0]

That's because they get you to put a standard exhaust on to make sure you 110% pass the test. So a retune is required.
