Precision Sound Balancing for Custom Dual Exhaust Builds
The Corsa PH0300 is a standalone 304 stainless steel H-pipe engineered for fabricators and enthusiasts building a custom dual exhaust system from the ground up. Connecting both exhaust legs at a right angle, this H-pipe balances backpressure between banks, smooths out exhaust pulses, and helps harmonize the tone across both sides of a dual exhaust setup.
Key Features
- Constructed from durable 304 stainless steel for long-term corrosion resistance
- 3.0 inch dual inlet and dual outlet configuration
- Compact 9.5 inch overall length for flexible placement in custom builds
- Balances pressure between both exhaust banks to reduce drone
- Weld-in installation for a clean, integrated fit
- Backed by CORSA’s reputation for dyno-tested, free-flowing exhaust components

Frequently Asked Questions
What is the PH0300?
The PH0300 is a standalone 304 stainless steel H-pipe with a 3.0 inch dual inlet and dual outlet configuration, designed to connect and balance both banks of a custom dual exhaust system.
Will the PH0300 fit my vehicle?
This is a universal fabrication component intended for custom exhaust builds rather than a specific vehicle, so it can be adapted to most 3.0 inch dual exhaust setups by a qualified fabricator.
What is the difference between an H-pipe and an X-pipe?
An H-pipe connects both exhaust legs with a single crossover section, while an X-pipe merges the flow more directly. Both balance pressure, but each produces a slightly different sound character.
Does the PH0300 require welding?
Yes, the PH0300 is designed as a weld-in component for a clean, integrated fit into a custom exhaust system.
What material is the PH0300 made from?
It is constructed from 304 stainless steel, which resists rust and corrosion for long-term durability.
Will the PH0300 reduce exhaust drone?
Yes, balancing pressure between the two exhaust banks with an H-pipe can help reduce unwanted drone at certain RPM ranges.
Is the PH0300 legal in all states?
Emissions and noise regulations vary by state and vehicle application, so check local laws before installation, especially if used with catalytic converter deletion.
Does the PH0300 come with a warranty?
CORSA backs its stainless steel components with a limited lifetime warranty against manufacturing defects.
Installation Instructions
- Raise and safely support the vehicle to access the exhaust system.
- Determine the desired placement for the H-pipe within the custom exhaust layout.
- Cut the exhaust piping to the correct length to accept the PH0300 inlets.
- Position the H-pipe so the crossover section is centered and level.
- Tack weld the H-pipe in place and verify alignment and clearance from the chassis.
- Complete full welds around each joint for a secure, leak-free connection.
- Inspect all welds and check for proper clearance from heat-sensitive components.
- Start the engine and check for leaks before lowering the vehicle.
