Just be aware that if you get ZX14 headers while they will bolt straight up:
- 2006-07 have a smaller midpipe connection diamter than the...
- 2008+ which also have the same midpipe connection diameter as the Concours
So if you find a set of 06-07 headers (which incidentally don't have catalytic converters) then you must ensure you buy exhausts for that year and Two Brothers
DO have 06-07 specific cans. If you have 06-07 headers and you get exhausts for 08+ the midpipe won't seal to the headers - unless you get a muffler shop to swell the tips to the right diametre, or you get an appropriate gasket fabbed.
And has been mentioned you will need a bracket for the left hand muffler - fab one yourself or buy one from Muzzys
AND lastly, your centre stand lever arm won't clear the midpipe properly so you will have to modify your stand, or get it modded by somewhere like Muzzys, or take it off.
