I have the Python 2 into I pipe, SERT and SE intake filter. Great torque and rumble accross the spectrum. Not overly loud at idile, but they bark when you get on it. I am happy for now.

 

I am somewhat happy, BUT, the muffler clamp/collector heat shield is a piece of crap!!

I had bad leaks, finally replaced it with a hefty clamp, the heat shield would not fit afterward, so I wrapped the entire pipe, including the collector...the heatshields over the headers fit after the wrap, I don't have any leaks now, and I guess I like the pipes, whattaya all think?they do sound good..
