Actually about 5000 times... :rolleyes:
I liked the sound on my stock SE with 2" pipes. When I went to 2 1/4 plumbing (Like SVT??) The low freq drone from 1200-2500 rpm got annoying in the cabin. I'd say pull the stock res and enjoy it for a few days, and then go get a hi-flow res installed before you go nuts.
