Titanium Megane Exhaust

November 7, 2016

So here it is! Our first Renault Megane 3 inch Titanium exhaust system.

 

Those of you looking to reduce weight for track use, this is the exhaust for you!

 

 

As usual we’re all about the details here at CGR, every kit will come with handmade titanium mounts and hangers, titanium bolts, custom Powerflex bushes, and two Machined Titanium V-bands for fitting.

 

 

 

How it weighs up; these are full exhaust system weights including mounting kits any clamps e.t.c;

 

The OEM 65mm Exhaust: 14.210kg

 

A competitor's 3” Exhaust: 16.920kg

 

Our Standard 3” stainless system with one silencer: 14.059kg

 

CGR 3″ Titanium system with one silencer: 7.143kg

 

 

 

 

Titanium

  

Generally speaking, Titanium is actually a less than ideal material to build exhausts from. It’s structural strength is greatly reduced at anything above 400-500 degrees C, and commercially pure titanium can begin to oxidise at the kind of temperatures car exhausts reach.

 

The alloy we use is specially sourced by ourselves and very VERY rare in the UK. It’s specifically designed to withstand heat 300-400 degrees C higher than commercially pure Titanium for extended periods of time, and at least 200 degrees C higher most other high-temp Ti alloys making it the optimised material to use.

 

It’s an extremely difficult material to work with and even more difficult to weld, meaning it requires a very specific set of skills in order to ensure the system is manufactured correctly. All welds are fully gas covered (hence the silver/straw weld colour) and back-purged to within a micron of their life in order to ensure complete structural integrity.
