Good afternoon all, I just purchased a 2018 Challenger SXT and also ordered the Trackhawk exhaust tips to have installed before I pick the car up. The Dodge dealership just advised me that the tips have arrived but they aren’t compatible with the car. My understanding is that they should just bolt on the same way as the OEM tips. Is there a difference between the mounts for the SXT versus the R/T and higher trim levels? Thanks in advance.
