ok,
so I went to Jedimasters favorite MOD store, the HOME DEPOT, and I picked up 8 3/8th's washers costing $1.08.
With my car being relatively new, it took little to no effort to get the cans disconnected. I simply jacked up one side at a time and unscrewed the bolts.
Done.
the sound? maybe a little loud for me.... I'm considering just doing this on one can, the passenger side one, maybe this will quite it down a little.
But for now I'm gonna keep it the way it is and enjoy the boxer burble!
