Raw American muscle on the outside and a refined, non-invasive performance exhaust note on the inside. The dramatic sound difference from outside to inside is accomplished by months of research and development as well as specific product design for the 2008-2014 Challenger 5.7 Hemi R/T (Auto). Fit, form and function are the cornerstones of our Solo Performance Challenger R/T exhaust kits. All of us at Solo Performance are very proud to bring to the Challenger community our free-flow MACH X-R/T (Auto) Exhaust kits. These kits are a 2 1/2″ mandrel bent stainless steel converter back exhaust.
We have had a lot of fun designing for this very “challenging” car and would like to thank Ontario Chrysler, London Chrysler, and Taylor Chrysler for the use of their cars and their invaluable feedback. Our MDS kit for the automatic is now also complete. The auto MDS kit includes J-pipes to cancel out the drone associated with the MDS. This was tested on a stock car and all other engine modifications may require adjustments to the J-pipes.
Exhaust Kit Specs
Front Muffler Assembly
2 1/2″ mandrel bent stainless steel exhaust pipes combined with our dual in dual out stainless steel MACH-X muffler. This is a true X design muffler that is 14″ long with a 4″ X 9″ body. The X design calms the noise and smooths out the rough RPM ranges while remaining free flow.
Right and Left tail pipe assembly using Solo Quad tips
3″ mandrel bent stainless steel pipe with a ball and flair front connection (where the tail pipe meets the front muffler assembly) to help with exhaust tip adjustments. Our tips are dual, staggered, beveled exhaust tips have dual 3 1/2″ outlets that were specifically designed for the Challenger.
Right and Left tail pipe assembly to be used with stock exhaust tips
These tail pipes are exactly the same as the ones described above except they have a rear ball (2 1/2″) which mates up to the flared stock exhaust tip. The stock “collar” must be used as well.
