OK, I wanted my 07 Blade decatted because I'm booked in for a custom map and came across a full header system right through to end can on ebay from a company called mymotoparts. They have thousands of good feedback and a UK number and website away from ebay. I phoned a guy called Steve and seems legit. A decat link pipe (bought elsewhere) is more expensive and requires cutting your original exhaust. So what your basically getting is a race system (in stainless) for just over £100 all in and get to keep your original exhaust headers to resell/refit. I've gone ahead and ordered so just need 4 header gaskets now.
