I just installed the Flowmaster Cat Back system tonight and I had to share. I am Very happy with it. The Install was easy and fast only took 1.5 hours and that was taking my time. The sound is Awesome and Deep and interior noise on the freeway is quiet.

thats iinteresting, they put 2 flowmasters in series on that. I installed only the muffler and not the entire system. it has a single 3 chamber flowmaster. It does have a bit more noise on the freeway and quite a bit louder under acceleration. I like the noise, but I think on a long trip I would like to get rid of that extra background noise, maybe I will try adding an additional muffler

Was there any welding involved or was it completely bolt on? Also how much did you pay for the entire cat back system? What is the part number? Thanks
