I considered these but after reading many posts about QC issues with Granatelli parts I decided to skip them and get some GT500 mufflers. After reading the comments about some freeway drone I'm glad I did. Although I will say the Granatelli's have a real nice looking tip. I wanted to love them, but I went with what I know works and I'm glad I did.
