hey guys, I just ground out the plugs on my 2012seuc. I went to harbor freight & bought a 5 pac of diamond disc for 4.99. It took me about an hour on each muffler. Dremmel would get hot & didn't want to burn it up. Had a hard time at first determining where to cut. Then,(after starting to cut the baffle) realized that I needed to cut in the smallest opening. Glad I caught myself before cuttin the baffle out. That was my fault for not payin closer attention to pics. Put every thing back. Dealership had previously removed cat, changed out header pipe, & se tuner. Sounds good (maybe a little flutter to it,)so far. Haven't been able to ride yet. Hard to tell with sound in garage. But I got $4.99 & 2hours in it. Like the comments have said. If youdon't like this option, then you can spend the $$$. By the way, I sat in a chair, stood muffler on intake end & just kept spinning the muffler round & round. this made for a nice clean & even cut. had a hard time with reinforced wheels, kept breaking out at center hole, tellin me they were too tight. Hey! a lil adversity, but it is all good. thanks for the post. Great comments. Like the website & the people. no bashin each other. THANKS HAIRD
