False Knock after Kooks 1 7/8" Lth install

[Mad Hatter]

Helping a track buddy with a S550 GT get a AED tune and Shawn found too much False Knock to be able to tune it. Went through the videos Shaun has on you-tube, but so far have not found any obvious knocks. Any ideas of where it can come from apart form the actual exhaust?? Though it might be the 1 and 7/8th header but does not have any sign of touching. At least we learned that this is what a false knock looks like!!

When they did the exhaust did they change mounts or anything else?

Looks like it just went away after checking everything. The AED video on youtube was helpful but never found any one obvious vibration. Just general house keeping with cables etc.

Make sure the steering shaft isn't hitting the pipes, especially if you are not using solid motor mounts.

The knocking went away after a general tyding up of cables etc. Never found anything definitive.
