No prob, that was just after Grip started up I believe, so their stuff was cheaper. That was a couple years ago though, so they may have changed their pricing since then.
I ended up going with Magnaflow. I felt like the WSII mufflers were too big, I was worried about not being able to tuck them under the bumper enough. And then if I did get em up there, I was worried about the tips melting my rear lip. But the deal breaker was I got the Magnaflow off PerformancePeddler for under $500 shipped. I think the WSII makes a great sound, and the Magnaflow sounds better with age, so they both have their pros.
Have you considered the Tanabe Hyper Medallion? When I rode in Rich's car that's what he had...and they sounded awesome. A little higher pitched and racy sounding, and they had this awesome popping when he would downshift. The WSII/Magna are a little deeper.
Probably more than you wanted to know, lol.
