Well after being inspired by ezekiel808's genius: 954 GP pipe mod
...I've decided to have a crack at this myself.
I have narrowed it down to an Akro megaphone
or a Graves GP slip on
as a starting point (the look I want, will be loud as all hell and the price is right). I ride 80-90% track days, so noise is not a primary concern. Will obviously get a custom map for the PC after final fitment.
I realise that I will most likely need a custom header made up for this (I currently have a Leo Vince slip on only, not a full system), I think it's a bit hopeful to think that I'll be able to cut and weld (or flange) my existing pipe, but wont know for sure until my new exhaust arrives.
If this is possible however, I would be happy for it to be bolted onto the existing exhaust hanger if only minor modification is required. If I do need custom headers, I think I would prefer the "traditional" R6 position.
I'm pretty determined to do this, and will muddle through myself if required, but any tips, pros/cons or advice of any nature would be welcomed - especially if anyone can point me in the right direction to a decent fabricator or exhaust specialist in Melbourne, or somewhere else in OZ...
Cheers and thanks in advance
