JBA makes catless mid pipes for these cars...... A local bud of mine has them on his '17 SRT392 Challenger......and holy shit its loud......I want it!
I heard the 392 sounds real good with the mid muffler delete but the 5.7 not so much. Or I should say read
Just make sure that shop is willing to put it back in..might make them plan ahead on how they cut it out
The 392 sounds better than the HC ....... with the muffs off. Haven't heard a 5.7 done that way yet though...
