I will tell you what, I got a MBRP cat back (T-304) and I am very pleased with it. I had a magnaflow, corsa, and borla all on my 04 hemi. The corsa was by far the best and for darn near $900 it should have been. I got the MBRP for just a tad over 400 with the 5 inch tip. I am very pleased with there construction. Its a good system for the $$$. The only thing that would make this system any better would be the band style clamps, but hey Dodge uses the U bolt style stock... good for them, good for me.
