I am still debating on whether to get the Flowmaster Super 40s or the Flowmaster 50 HD, to put on my 2005 Hemi. I heard that the 50 HD allows for better performance (more flow), but I like the way the Super 40s sound. Does anyone have good sound clips of either one?
If you have Super 40's, did you feel like you lost some HP or torque?
Thanks

 

i had magnaflow and changed to 40's they sound better as for flow the differance between 40 and 50 is not that much i would go with 40's

 

I have a super 40 and this thing is loud. I love that muscle sound. I have a clip and I will try to get it up ASAP. Along the lines of "flow" the super 40's casing is thicker so it makes up for the short length. The 50 is nice but too quiet for me.

 

Yeah I think that I will go with the Super 40s. I was just worried about losing some HP or torque. Should I go with a cat-back system? What is the difference between the catback exhaust pipes and the stock pipes?

 

heres a few sound clips of my super 40's
