So Cal H2 is off the scale

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

Orbital H2 The first muffler is a resonator it eliminates harmonic resonance in the cab the second is a 50 series HD muffler. Here is the link to flowmaster.

Spike The kit is a complete bolt on kit. It went on easy and fit perfect. I paid $364.34 (Retail $565.52)for the complete kit. Part # 17376 The best price I could find at http://www.summitracing.com it was a special order took 1 week + free shipping the price was worth the wait.
