I would consider doing it. I was highly considering going Graves, but decided to get the Akrapovic instead, just due to convenience. Well, if you're going to ride on the track. Then you can keep one nice.
Not sure if I will tho. Main reason for wanting to change my can, is because it faded into a yellow-brown color.. kinda ugly lol.
Graves is $1499 for the system even with 15% off, it would still be a bit of money to throw away mainly cuz my twobro tip is ugly lol.
Might just order a new twobro tip n not have to spend 1000$ extra if I dont need to
