Custom Lexus IS-F Exhaust by Royal Muffler

Listen to this custom Lexus IS-F exhaust treatment from Royal Muffler, a company based out of California:

This design is unique among the current IS-F options as it’s using four race mufflers rather than the more typical muffler/resonator combination. According to Club Lexus, the price is $2,300, which includes install and lifetime warranty. Certainly on the pricy side, but it’s hard to argue the results.
