I have seen pictures of the Crossfire limited (N/A) muffler and I own and SRT 6. The mufflers are different. Plus the SRT 6 has a resonator on the driver side in front of the rear axel. You can insert a broom stick 14 inches into the SRT muffler (from the lower side of the oblong tip) before you hit any baffles from either tip. The SRT muffler has one pipe coming in from the resonator and two going out to the oblong tips. The standard crossfire has two pipes routed from chamber to chamber in the back of the muffler. I think an SRT muffler (with out a resonator) would work well on a standard crossfire.
