Test pipe tune

[WimpyS4]

Anyone have a company that still does a tune for the b8 s4 that eliminates the CEL from test pipes? APR just removed their tune thanks to the epa and I preferably didnt want to do the spacers because they're unreliable.

J-bend O2 spacers from Vibrant

034 has a test pipe file that quite a few of us are running. However, it will not pass OBDII emissions because it disables the catalyst monitors. After about a dozen different attempts at various spacer configurations that was the route I ended up going. No regrets at all.

IE all stg2 files are TP files,
