I'm new to the forum and to Miata's and am thinking very seriously about the Twin Tip as a first fun modification. For what it's worth, I'm not interested in any sort of competition and don't currently plan add a header. Probably some sway bars and that may be it.
I believe it has been stated in various places that the Super Street is roughly 35% louder than stock while the Super-Q is about 15% louder. Given the Twin-Tip is roughly the same volume as the Super Street coming out of the box, and it has been stated that it can be muffled a bit more then the Super Street because to the two tips, is it safe to assume that, if desired, which I'm not at all sure it would be, the Twin-Tip could be dropped to perhaps 20-25% louder than stock?
Also, if I understand correctly, the Twin-Tip has a bit lower note than the Super Street (which I like!), and that installing a baffle in the left tip will drop that note even more. Is it safe to assume that installing an optional packed baffle would drop the note more still?
Edit: Also, regarding the Super-Q. Is the 15% louder than stock with the baffle installed? And if so, how much louder is it without the baffle? 20-25%?
