Have any of you installed or heard/used the Flowmaster Stainless Steel American Thunder "aggressive sound" 409S header-back system?

It has 2.5 pipes which should mate nicely with my Hooker Headers.

Its part #817409 and comes with the Super 40 Series mufflers.

Looking to buy and want some feedback from my fellow CO members...

 

Im a big fan of running an x pipe i like the pypes exhaust because it offers one in their kits but i have never run one of their kit . I currently run and x pipe and hooker aero chamber mufflers. My car actually ran faster through the mufflers with the x pipe than with open headers .

 

I had that same system installed on my SX (455 engine) but thought it sounded pretty good. Had a video of me starting it up in my driveway.

i have mondello ceramic headers on my stock 330 with Summit Racing's 3" dual with Summit brand mufflers.
it sounds awesome!

 

I have the 2.5" system on my 72 with super 44 mufflers. It fit decent and sounds good on my 350. I got a video on you tube if I can find it
