Every Milltek system is designed, developed and hand-finished here in the UK by time-served craftsmen, each one produced in aerospace grade type 304, non-magnetic stainless steel. This superior material is less susceptible to discolouration, lasts almost indefinitely and is used throughout the entire construction of our pipework, silencers and associated hardware.Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters are carefully enlarged over stock to ensure ultimate performance without the loss of mid-range torque. All of the Milltek exhaust systems endure a comprehensive acoustic development process to deliver a tone that is sporty and crisp, without ever inducing NVH, drone or cabin resonance.We always recommend the exhaust is fitted by a competent garage or tuning workshop so normally avoid issuing install guides.MILLTEK EU TYPE-APPROVAL CERTIFICATEThe systems are 2.76 inch (70mm tube) and there are downpipes available to remove the OPF with and without Hi Flow Sports Cats.The pre sept systems require re-use of the OEM Valve actuator, however the post sept models changed, and we therefore now supply the correct actuator to work with the same system.There is also an Active Valve Control available for these models to give the user complete control over the valve positions at different drive modes / ranges.The OPF-Back System is EC Approved. 

Choosing the right Maxton kit for you!

Our vehicle lookup system on progressiveparts.com is based on engine specification within a model variant. It does not cater for a vehicle's body style (i.e. Hatchback/Sportback/Saloon/Estate etc).It is important for customers to check the specification of their own vehicle against the product description, and if their vehicle has an existing sports trim levl, body kit or factory enhancement that may cause it to look different from other similar models. For example: Volkswagen R-Line, BMW M-Power/M-Pack, Audi S-Line, Ford ST-Line, Merc AMG-Line, Seat FR.  These kits will not fit models that don't meet these specifications.

Installation & Fitting

Instructions & GuidesMaxton Design provide either an online reference (below) or printed instructions with their products, we can't stress enough how important it is to follow these guidelines. Not only does this create a safe, aesthetically well fitted product, but it increases the longevity and lifespan of the kit.Neither Stox Autosport nor Maxton Design will be unable to provide and support or warranty for products fitted incorrectly. For example, front splitters require the front bumper to be removed, without doing so the bolts will be incorrectly positioned and may not be able to cope with the down-force exerted on it. Straying from the guidelines in this manner must be done so at the owners risk.Fibreglass & "Non-Prepped" ProductsBy adding these products to your basket you are agreeing to the below statement.All Maxton Design Fibreglass products including certain bumpers, spoilers, spoiler extensions and skirts will require “prep” before installing.These are not a simple 'ready to fit' modification. In transit, the items may get chipped or marked and as such prior to painting it is important you understand that the parts may require filling, sanding and repairing (defined "prep") prior to paint being applied, which can be undertaken by any reputable body shop at minimal cost.Return requests based on not anticipating the definition above are not accepted, please be aware you have agreed to this statement and the definition of “prep” work required prior to purchasing.
