E430 exhaust query (trolls need not reply)
I did some exhaust work a couple months ago on my E430, deleting the resonator.
I didn't have immediate access to the correct pipe pieces to re connect the two halfs, so I was driving around for a bit with just the catalytic converters (4) and dumping out the sides. It sounded awesome. EXTREMELY loud at WOT under load, but a very nice grumble at idle and not bad at all on the highway.
When I finally did have what I needed to re assemble the system
properly, with the resonator deleted, I was less than impressed with the result.
My question is if I delete the converters, with the O2 sensors upstream, will this cause the MIL lamp to come on?
There are no enforced emissions regulations in my province.

So by saying you were less than impressed with hooking up the rest of the system, are you talking sound or performance?
If sound, you could just get a different muffler setup to open it back up downstream (eliminate the 1st muffler and replace the last muffler with a straight through type) so you still have emissions properly gauging your air fuel ratio AND you can have that nice MIL light still turn on when a major issue arises?

The 1996 I6 engine is different than V6 and V8 engines of next generation.
The V6 and V8 are having 4 of O2 sensors.
Not having smog test, I think high flow cats are your best option.
Bare in mind that smog requirements are coming to more and more jurisdictions and your province might do it in next few years.
California made smog for diesels about 6 years ago and grandfathered it back to 1998 models.
That made owners of modified diesel pickups pretty scare.
