It is not high grade Titanium.
High grade Titanium can't be bent and exhaust noise will be raspier.
Akrapovic is using stainless mixed Titanium, and charge you a full Titanium price.
Stainless is softer material and make the exhaust noise deeper. |
From their own site, it LITERALLY says " Built from high-grade lightweight titanium to reduce weight, with valve housings cast in the in-house foundry, the Evolution Line (Titanium) exhaust system fits directly onto the BMW M5’s stock downpipes." |
