has anybody figured out which spacer doesnt provide CEL code with just a downpipe? I got my downpipe coming in this week and need a working spacer until its time for a tune.

Tried the Fabspeed spacer with my Titan downpipe and it didn't work for me.

i think the only downpipe that has guaranteed no CEL is the active autowerke one. All the others will throw a CEL but that can be flashed away with BM3 or MHD if i remember correctly.

FYI, I've got bm3 and still have a cel for heater circuit. Tune doesn't mean you won't code.

Have you eliminated the codes or tune only? I believe there is a tab specifically for that.

On another note, how do you like it? I was looking into AMS and BM3 soon

Removed my spacer/defouler and codes have not come back. That was at the recommendation of ProTuningFreaks.

Dp and tune is very noticable. Car is definitely in the 400hp club

Guys, these extenders just don't work, I had the CEL come on even after installing big daddies extender, piece of $&#t, and I decided to remove it today and found the whole cat material gone, with only 3000 miles on it, on stock turbo, these ghetto parts definatley can't take boost.

Stick with a flash to override the CEL or just keep deleting the code when it pops like I do through the JB4.

Same here, I had the Fabspeed one and it didn't prevent the CEL either. Only thing I found is using tune to prevent.
