I had the same thought after I ordered a new Akra EVO system w/carbon can.
I have part numbers for just the mid pipe/link pipe from the EVO. When the bike comes in I will see if the mid pipe connects to the headers. I think it will.
If this does work out it will be a very Inexpensive alternative to another full system. About $400
I put the Akra EVO w/short muffler on my friends bike last year, I will try
his link pipe & short muffler too. If someone wants this instead they will need the hanger from the right side rear set or aftermarket rear sets.
eBay & this forum has the right side rear set for sale all the time cheap.
Time will tell.
$1800 for the system is a great deal! That's a $2984 system retail from Sierra BMW
This will be great for the guy that has to keep is bike stock & use factory parts. Should sell with no problem at that price.
