Defender 110 / 130 300Tdi Exhaust Systems

4th January 2019


Big Bore 2.5″ Diameter 300Tdi 110 Exhaust Systems with two silencer options.



We like our Land Rovers, and so all our Defender systems have been designed, built and tested in house by our passionate engineers.

All our 300Tdi Systems come with a Standard looking Slash cut tip, with our branding.


Size Matters

Every system is fully T304 stainless, Fully TIG welded by hand and Back-purged to ensure the best quality.  We use 2.5″ diameter Stainless T304 Tube, Mandrel Bent in house.

This diameter of Tube, has been used in turbo applications by us for engines up to 450Bhp, and is therefore more than adequate for a well tuned Land Rover.  Should you wish for a 3″ or even bigger system, don’t forget that we can make you  a custom one-off with a visit to us in Sunny* Suffolk.

Material world

Our silencers are filled with a mixture of stainless wool, and Glass Fibre mat which allows for a ‘solid and deep’ accoustic sound.  Nothing like the ‘tinny’ sounding traditional Stainless Exhausts of old.

Our Flexible joints are carefully made with three walls to provide great reliability, and are completely T304 stainless, unlike a lot of our competition.

Our Flanges are Laser cut, again in T304 stainless, and carefully mirror the flange positions of the Land Rover OEM systems.  This means that any section should be fully compatible with a Land Rover OEM one.  Please ensure that you have the OEM Land Rover exhaust fitted before relying on this.  We have had so many people come back to us having tried to replace a PATTERN exhaust section with one of ours.  If in doubt go for an entire system.  It’ll be the last exhaust you buy.

Our hangers are T304 stainless, like the rest of the exhaust, they’re basic and they work.


Our exhausts are supplied with Gaskets, and Stainless nuts and bolts where appropriate.  We offer a fixed price £60 fitting charge here in our workshops in Suffolk.


Our Prices shown here include VAT.

Don’t stop now!

As we get more and more requests, we will be adding further options to the shop for Cats, Silencers, tailpipes, and sound.  We have a Valved system currently in development that we’re very excited about!
