Thanks for information. I see on Milltek's web page there are two options re the downpipe.
"Large-bore Downpipe & Decat" for Race/Track only
And
"Large Bore Downpipes & HighFlow Sports Cat"-requires Lambda extensions
Have you / are you fitting the first option?
Also
"Just as a side note, if you fit downpipes you'll likely bring up the CEL" what's CEL an error?
Finally any idea what Milltek mean when they write "Lambda extensions"  |
CEL, is check engine light, or engine management light.
