Toomey's are the best pipe if you are NEVER planning to do any port work. They were designed to be the ultimate pipe for the "UNPORTED" 'Shee engine, & I think they are. I've got the TR6's on my '01 along with a Noss Head, Trinity 2n1 35 single carb & am very happy with the power & ridability. The build quality-welds, chrome, fit, & silencers are great.
