I've just returned from local main dealership to see if I could resolve the fueling issue with straight tho pipes.
Service guy said that fueling should not be effected adversely by fitting pipes. The existing mapping can be altered by +/- 6% if the emissions proved to need adjusting. He suggested having it checked at next service for peace of mind.
I also asked about warranty issues of removing Cat (and also stock slave cylinder). Im told that these mods wouldn't effect warranty.
Meanwhile, my new 14T sprocket arrived today! Little job for tomorrow!!
