Anyone ever hear one of these exhausts or know about them at all? How loud it is how quiet?

 

Espelir is the s.hit. period. none are out for the G35's yet. they're still in the making. they're available for the 350Z though. i've had Espelir on previous cars, and it's top notch, real JDM (actually made in japan). no rice notes either. put it this way, if Mackin Industries is a distributor, it's got to be super quality/performance products.
