If its a genuine kit for the 749R it comes with the throttle inlets trumpets too. Ti end can and 57mm pipework.

two types of pipework, early type thats a bugger to fit and involves a 'mod' and the later type with the 'bannana' pipe (love that description!)

749R ecu, nothing special, PC3 and custom map essential - Seconded!!!

if buying second hand expect the ECU to be useless, so budget for a Power commander.

the full systems with Ti cans were discounted and available as 'just pipework' system for about £1700 new. the 749R system (with filters, ecu and trumpets) is/was £2700 ish. but you'll be lucky to find one 2nd hand.
