Yes,
I would have to agree about the second time round thing.
I have now completed assembling the passenger side of my pipes and already can see how I could have made life easier if only my crystal ball wasn't so dirty!!
I am counting on the muffling effects of the cats to hopefully drop a few Db's from the note. The flow isn't such a huge issue for me with the relatively low output of my combo (275 Kw).
The primary length thing is in the bag though, around 1000mm surely is enough!!
