Turbo-Back Exhaust Systems

Turbo-back systems replace the entire exhaust from the turbocharger outlet to the tailpipe. This delivers maximum performance gains on turbocharged vehicles by eliminating all restrictions.

What's Included

Downpipe (from turbo)
Catalytic converter or test pipe
Mid-pipe
Muffler and tailpipe
All hardware

Performance Benefits

Turbo engines are very sensitive to backpressure. A turbo-back system can add 25-50+ HP by:

Reducing exhaust backpressure on turbine
Faster turbo spool
Lower exhaust gas temperatures
Improved turbo efficiency

Emissions Note

Some turbo-back systems include high-flow catalytic converters for street legality. Others include test pipes for off-road/race use only. Check product descriptions for details.

Frequently Asked Questions

What's included in a turbo-back exhaust system?

Turbo-back systems include everything from the turbocharger outlet to the tailpipe: downpipe, catalytic converter (or test pipe), mid-pipe, muffler, and tailpipe. Some systems offer catted (with high-flow cat) or catless (test pipe) downpipe options. It's the most complete exhaust upgrade for turbocharged vehicles.

How much power does a turbo-back exhaust add?

Turbo-back systems can add 25-50+ horsepower on stock turbo applications because turbo engines are very sensitive to exhaust backpressure. The turbo spools faster, exhaust gas temperatures drop, and the turbo operates more efficiently. Combined with a tune, gains can exceed 50 horsepower on many platforms like the WRX and EcoBoost.

Is a turbo-back exhaust street legal?

It depends on the specific system. Turbo-back systems with high-flow catalytic converters are street legal and emissions-compliant. Systems with test pipes or catless downpipes are for off-road/race use only and will fail emissions tests and trigger check engine lights. Check product descriptions for catted vs catless options.

What's the difference between turbo-back and cat-back for turbo cars?

Cat-back keeps the factory downpipe and catalytic converter, replacing only from the cat back. Turbo-back replaces everything from the turbo, including the restrictive factory downpipe. Turbo-back offers significantly more power gains (25-50+ HP vs 10-20 HP) because the downpipe is a major restriction point on turbo vehicles.

Do I need a tune with a turbo-back exhaust?

A tune is highly recommended with turbo-back systems, especially catless setups. The significantly reduced backpressure changes air/fuel ratios and boost characteristics. A proper tune prevents lean conditions, optimizes boost, and unlocks the full power potential. Most owners consider the tune part of the complete turbo-back upgrade.
