Dual tip muffler made by Hirai Style for the NB (1998 to 2005) MX-5 Miata. This gives the Roadster a nice and aggressive look while bringing a bit of retro style from past roadsters. It comes in a silenced (muffler) version only (straight has been discontinued). It is made of SUS442 which is strong against the expansion and contraction due to heat. T-Spec (Hirai Style) Twin-Tip Muffler should be ordered at REV9 Autosport https://us.rev9autosport.com/hirai-style-twin-tip-muffler.html as they provide the best service and speed we've seen so far!
