A closer look at the natural coloring after a few months on this full custom titanium exhaust we built for the GTC4Lusso.

The heat brings out some awesome colors in the titanium, and this one turned out beautiful! Sometimes we enjoy leaving the raw form and letting the exhaust temps do its own thing

TITANIUM TUESDAY

Little throwback to this Ferrari GTC4Lusso we built a full custom titanium exhaust for including material from Ticon, Stainless Bros, and Gesi G-Sport Converters. This thing turned out insane with a full 3” Ti exhaust integrating a custom double X-pipe mid section!

Every customer who has brought their car to us has played a part in getting us to where we are today. That continued support is what made it possible for us to grow into this second shop, and we couldn’t have done it without you. We truly appreciate everyone who has been a part of this journey and helped make this next step possible!
