With a FMIC and the JCW exhaust? I know the JCW is not considered a true free flow 3" exhaust but can it be done? Or just Stage 1 only. Thanks!

 

stage one only on a stock R56 jcw exhaust

 

Even if I have a FMIC?

 

Yep, makes no diff, yours( and mine ) exhaust is too stuffed up . I don't think the 2nd stage tune thing is gonna matter too much anyways. You would have to run a loud, and/or code throwing exhaust to use the #2

 

I run a stage 2 with a helix fmic + akrapovic dp + jcw factory exhaust. Runs well....

 

there you go..... change some of the JCW exhaust( the cat) and you will be OK, thanks for the info ( how much diff are you seeing with the stage two?)

 

Just wanted to put a disclaimer on this.. Although this is what i'm running right now, this was against ALTA's recommendations. Per Alta, i should stick to stage 1 fmic regardless if i have an aftermarket dp unless i have a 2.5" or bigger exhaust system. With the jcw being to about 2.25", i figured its worth a shot.

From a difference perspective, big pull difference but nothing like you get wet in your pants.

Hope this helps.
