Titanium Exhaust Fabrication

Grade 2 Titanium and Heat Management

Standard stainless steel exhausts are heavy and hold onto heat for too long. We use Grade 2 titanium sourced from a specialist supplier in Sheffield to build systems that weigh about 42% less than factory parts. For example, on a recent Ferrari 488 project, the owner saved 14.3kg just by swapping the rear section. Titanium handles heat cycles better than steel, which means the exhaust cools down faster after a hard run. This helps protect the sensitive rubber seals and wiring looms in the engine bay of mid-engined cars.

TIG Welding with Full Back-Purging

Welding titanium is different from working with mild steel or aluminium. If oxygen touches the back of the weld while it is hot, the metal becomes brittle and will crack within a few months. We use a process called back-purging, where we fill the inside of the pipe with pure argon gas before we start the arc. This keeps the internal joints smooth and strong. Every pipe we cut has lathe-turned precision to ensure the fitment is tight before the torch even touches the metal. We have completed 47 of these full systems since we opened our Southampton workshop in 2017.

The Performance Effect on the Dyno

Back pressure check is a vital part of our fabrication process. We do not just weld pipes together; we calculate the diameter needed for the specific engine displacement. A system that is too wide loses low-end torque, while one that is too narrow restricts the top end. Most of our Maserati clients see a modest bump of 8-12 horsepower once the car is on the dyno, but the real gain is in the throttle response. By the way, the sound profile changes too. Titanium has a higher natural frequency than steel, giving Italian V8 and V12 engines a crisp, sharp note that does not drone at motorway speeds.

Durability in the Southampton Salt Air

Living near the coast means salt air is a constant threat to car underbodies. While stainless steel can still tea-stain or pit over three or four winters, titanium is almost entirely immune to corrosion from road salt. We have seen cars come back for a routine oil change three years after a fitment, and the exhaust still looks exactly like the day it left the shop. We use 1.2mm wall thickness for the main tubing, which provides the right balance between weight saving and structural strength for daily driving on UK roads.

Our Fabrication Process

• Initial 3.2-hour inspection and CAD measurement of the vehicle underbody.
• Material selection using only Grade 2 titanium for the main runs and Grade 5 for the mounting hangers.
• Precision cutting and deburring of all sections to ensure zero internal turbulence.
• Multi-stage TIG welding with dual-flow argon regulators.
• Final fitment check and heat-cycle testing to ensure no expansion rattles against the chassis.

Fixed Pricing and Timelines

We are upfront about the cost because titanium is a volatile commodity. A typical cat-back system for a Lamborghini Huracan or similar V10 starts at £3,850 including all materials and labor. Most projects take 12 to 16 business days to complete from the moment the car enters our Oxford Road unit. We do not rush these builds because titanium requires patience during the cooling phases between welds. If you have a specific design in mind for the tips, we can turn those on the lathe to your exact diameter and finish.
