Wondering if a titanium exhaust on a catless N55 M2 really makes any difference in sound. Unlike most car platforms every video I see of an N55 M2 exhaust sounds IDENTICAL. From a 300 muffler delete to a 4500 dollar titanium turbo back, all sounds the same (in videos). Does a titanium give a more "trumpet-like" or whaling sound (sort of like a GT3RS)? Or is it only for weight savings?

I haven't heard one in person, but I've done research on titanium exhausts. The sound would be raspier due to the decreased exhaust wall thickness. Titanium being stronger than steel, you need less material for the same strength.

For the cost, you're only saving like 10lbs.

I looked into replicating my MPE in titanium, but decided against it. Too much $ and work, not enough benefit.

It sounds great. I have an Akra. there is no drone, sounds exotic in person and best thing of it will never rust
