Not enough difference to justify $3,500 in my opinion. You could have told me the gray car had a stock exhaust but with a resonator removed and I would have believed you.
still most interested in Remark because of the weight claim....
Looks like section to section Remark is 5lb less because Remark claim the front pipe back as 22lb....this doesn't include front pipe and is 19.2kg or 27.5lb...
