Are you happy w/ them? Did you see any marginal gains w/ them?
Whom did you get them from?

 

I love mine...the sounds are great...I dynoed at 375/476 with just dynatechs and a magnafolw cat back. I got mine from rpm outlet.

I have them,,, Put them on in the summer, didn't dyno or run it at the strip, but I can't say that I felt any gain just by driving it on the road... I have Dynatecs long tubes and Bassani to the rear... Very loud, Keep in mind I'm old and to much rock and roll has deteriorated my hearing ..LOL.... But I like them........... Hope this helps..........
