exhaust system

[wyocummins]

hey guys new to the forums here....quick question is there anyone that runs a strait pipe exhaust system with just a muffler and is fooling the emissions system? i keep getting the p0430 code and curious if there is a way around it...

If you get the URD O2 sim you won't get a CEL, fyi if you remove the front two cats, you'll get a CEL, if you remove the rear cats you won't get a CEL. whats the spec on the exhaust? Are you N/A or have F/I.

I have true dual straights and have never thrown a code. as long as you cut behind the o2 sensors, you shouldn't have a problem..
