|David in Tallahassee||
Non foulers didn't do it for me. Still got an annoying CEL intermittently. I ended up using this o2 simulator:
Has worked perfectly for two years plus!

|christian900se||I meant even if you have no CEL for the downstream o2 sensor, and everything is operating properly: would turning off the rear o2 sensor make your otherwise emissions legal car fail?|
|09-28-2009 05:22 PM|
yes and here it is...just gotta drill it out.

|GreySPG||yesssir. right above clearwater. i'm takin the first muffler out. and transitioning down to the stock pipe before the two bends when then go over the axle|
|09-28-2009 04:00 PM|
|GreySPG||yeah I put 06 aero sport combi rims on the vig...tinted windows, lowered, rear sway bar, and this simple project along with ss brake lines. 3 bucks for a simple o2 extender saves alot of hassle. thanks buddy|

OK.....I forgot that the Vig had the larger pipes as a standard item, so necking down from 3" to 2.5 should be totally fine, especially that far back.
I'd leave one cat there to prevent T7 from going batshit crazy -- and in case New Hampster decides to start doing visual checks -- but use the extender...
That's going to be a nice sounding system....Are you deleting both the center resonator and the back box, or necking down just before the back box?
EDIT: You're in Florida now? I think they got rid of inspections....

|GreySPG||jsut gotta find one of those antifouler. ..... btw mike.... florida is great.|
|09-28-2009 03:55 PM|
|GreySPG||yeah its 2.5|
|09-28-2009 03:52 PM|
Yep....the anti-fouler should help with that....
Is the stock Viggen system 2.5"??
|09-28-2009 03:51 PM|
|GreySPG||and your saying to extend the sec o2 sensor out to prevent the engine light to come on|
|09-28-2009 03:50 PM|
|GreySPG||i'm goin 3" into the stock exhaust before the rear axle. getting rid of both cats and the one muffler.|
|09-28-2009 03:49 PM|
|GreySPG||hmmmm excellent. looks just like a bunch of male/female plugs then screw on the o2 sensor.|

Best bet is to use a cat. You're not going to lose much power, if any, and you're saving the earth one drive at a time. Use a cheap Catco cat and you're set.
When you do that...or instead of doing that...weld in an 02 bung after the cat, then screw in an O2 sensor extender (also called a "spark plug anti-fouler") That might remove the CEL.
|09-28-2009 03:19 PM|
so then if i keep the second o2 sensor what will happen besides check engine light?
|09-28-2009 02:27 PM|
|GreySPG||i dont care about emissions, just functionality. i dont have access to t7 suite. So i can put the o2 sensor in and pop a cell but the car would run fine?|
