      Force 11 Exhaust.

      Flow master force 11 exhaust came with all the parts necessary to install. All parts were of high quality and fit perfectly. I chose to have the tail pipes welded but the U clamps would have worked fine. Now I have a slightly deeper sounding exhaust without it being too loud or over bearing. I highly recommed the Force Il cat back system.

      Love flowmstr

      Bought the car with mac muffers and the drone was unbearable at 2000rpm. The three chamber flow masters are perfect.

      Great addition to the system Flowmaster

      I added this to MAC H-pipes and MAC headers for the complete resto of my 89'. The sound is great. The picture shows the tips I put on after the cut the down turns off the end of the pipes. Great item.

      Flowmaster Force II's

      Installed the Flowmaster Force II kit on my 90 GT vert. Fit well and sounds great. Gives the classic flowmaster tone without being too loud like some of the other flowmaster kits. Recommended for anyone who wants the flowmaster sound without being too loud.
