I installed them right away, good fit and the soun...d is amazing. I actually can't wait to go to work in the morning... lol Higher pitch than the 40 series and more modern... Very strong and loud, sounds better when downshifting... I have a 2001 mustang gt 4.6 flows are for stangs... and um a Chevy man, so that's saying allot... why a stang??? Couldn't pass up a great deal!

I had been running straight pipes on my car but wanted to quiet ...it down...a LITTLE. These were perfect!!! Still a good, loud sound but I now have backflow. They sound great on my Challenger!!
