Custom Exhaust Systems & Fabrication for Performance Builds
Custom systems designed and built for your project.
Alexander Zyryanov
Performance Fabrication
Fabrication for engine swaps, tight engine bays and projects requiring custom parts.
4. Complex Fabrication
Complete exhaust systems designed for heat management, engine response and durability under load.
3. Full Exhaust Systems
Aluminum and stainless steel piping for turbo builds, with routing and diameters matched to the setup.
2. Turbo & Intake Piping
Custom exhaust headers for your engine and setup, designed to fit the available space.

What We Build
APPROACH
Every project starts with engineering.
Full-penetration welds with attention to finish and weld quality.
[ 04 ] Finish
Designed for heat, pressure and motorsport loads.
[ 03 ] Designed for Load
Designed to fit tight spaces and complex layouts.
[ 02 ] Built to Fit
Calculated runner lengths, pipe diameters and flow.
[ 01 ] Geometry First
Who This Is For
Custom fabrication for engine swaps and modified builds where off-the-shelf parts do not fit.
Experience across motorsport disciplines helps guide material and fabrication choices for the loads each component will face.
(01) Custom Builds
Water-cooled exhaust manifolds for marine swaps, including LS7 installations. A dozen built for boats in Russia.

Pictured: Honda C35A.
(02) Motorsport
Welding for industrial applications, with material selection and weld preparation for radiographic or ultrasonic inspection.
(03) Marine
(04) Manufacturing
SELECTED WORK
Result:
Consistent performance and engine response under load.
Solution:
Revised routing to retain approximately 370 mm runner lengths within the available space.
Challenge:
Fit a correctly sized header into a tight engine bay while retaining the required runner length.
Custom Exhaust Header
Result:
Compact manifolds allow engine removal with the manifolds attached, reduce heat buildup under the hood and operate on 1,000 hp engines.
Solution:
Used 3D scanning and modeling to design the manifolds, then 3D-printed the parts in metal.
Challenge:
Fit an LS7 into a Nissan 400Z, with compact exhaust manifolds that clear the steering column and engine components.
Custom Exhaust Header
Result:
Both V6 engines run at high RPM with functioning oxygen sensors and no reported water ingress.
Solution:
Designed double-walled exhaust manifolds to cool the exhaust gases.
Challenge:
Build water-cooled exhaust manifolds for a boat, reduce engine compartment heat and prevent water from entering the engines.
Marine Exhaust Manifolds
Result:
Prepared the qualification weld for radiographic inspection and destructive testing for oil and gas applications.
Solution:
TIG-welded AISI 321 stainless steel pipe (Ø76 × 7 mm) with ER316LSi filler, internal argon purging and controlled parameters for full penetration.
Challenge:
Produce a qualification weld for oil and gas company certification, including non-destructive and destructive testing.

About
Each system is designed to fit the available space, perform under load and withstand operating conditions.
I specialize in custom exhaust systems and fabrication for performance builds and motorsport, working with stainless steel, titanium, aluminum and magnesium.
