Exceptional price: €324 (below manufacturing cost).

In 2015, we developed the first F1-style merged exhaust manifold for the Renault 5 GT Turbo / Renault 11 Turbo. The current version is the latest evolution (2023), the result of many years of development, testing, and real competition use.

After 9 years, non-reinforced copies have appeared on the market, sold even €140 cheaper than the original product.

We have decided to sell these manifolds at a loss, pricing them below the copies, so you can benefit from the original product, reinforced, manufactured in Spain, and proven for years in competition.

Proven in competition

This manifold has been successfully used since 2016 by:

• Carracedo – Renault 5 GT Turbo (Rally)

• Víctor Quiroga – Renault 5 GT Turbo (+270 hp)

• Juan José Couceiro – Renault 5 GT Turbo (+270 hp)

• …among other high-performance builds

Main advantages

• Increased engine power and torque

• Noticeable improvement in exhaust sound

• Lower engine temperatures thanks to reduced exhaust restriction

• Increased reliability, with all runners of equal length

• Reduced risk of detonation on cylinders 1 and 2, common with the standard manifold due to short exhaust paths

• Weight reduction of over 2 kg compared to the stock manifold

 There are no disadvantages compared to the original manifold, making it suitable for standard engines as well as competition engines.

Design and performance

Custom in-house manufacturing, designed to achieve the best geometry and maximum flow, using computer-aided design and fluid dynamics analysis (CAD & CFD).

• Increased power and torque thanks to F1-style runner merging

• Larger tube diameter (38 mm) to improve exhaust gas flow and power output

• Dramatically improved exhaust sound, delivering a cleaner, deeper, and more refined tone

Reliability

Designed for maximum durability:

• Structural reinforcement using a continuous 12 mm steel plate, supporting the weight of the turbocharger instead of the manifold runners themselves, which cannot withstand mechanical stress at high temperatures.

• Minimal number of welds (only one per runner), eliminating weak points and significantly increasing long-term reliability.

Technical specifications

• In-house design developed in Spain by engineers

• Computer-designed with fluid dynamics analysis (CAD & CFD)

• CNC-bent tubes to allow a single weld per runner

• 38 mm diameter stainless steel tubing

• Total weight: 3.3 kg (2.3 kg lighter than the stock manifold)

• F1-style runner merging

• 100% in-house manufacturing in Spain

Installation

Installation with original Renault Sport nuts is strongly recommended, as they are the only ones guaranteed not to loosen under vibration and high temperatures
(available in related products).

IMPORTANT INSTALLATION NOTE

This manifold has been designed exclusively for maximum performance.
To achieve this, it features:

• Large-diameter runners (38 mm)

• Smooth, wide-radius bends

• Equal-length runners, occupying the maximum available space

For this reason, it is not compatible with the original starter motor.
A more compact starter motor is required (available in related products).
