Hi all,


Manufactured here in house in the UK, with all joints utilising superior flanges and bolts as opposed to lesser quality sleeve jointing with clamps. The Tuning Developments CAT Back Exhaust is made from high quality T304 grade stainless steel, which is mandrel bent ensuring that pipes aren't crushed or deformed when being bent for better gas flow and sustained pipe bore size throughout the system, this in turn helping to maximise performance gains. On top of all this, the weight of this exhaust system is substantially less than the factory system, improving performance further again! The exhaust is also fabricated with further modifications in mind, neatly tucked up to the underneath of the chassis so that clearance is not an issue, even on lowered cars with coilovers fitted.

This CAT Back Exhaust System from Tuning Developments will interchange with the factory downpipe/cat section of exhaust, making install very simple and straight forward, but ensures a true full 3inch Exhaust with a clever adaptor which can be removed when upgrading to our 3inch Decat/Downpipe later on, it also utilises factory hanging points to ensure fitment is as good as the factory exhaust system.
The Tuning Developments CAT Back Exhaust system is available with or without a resonated center section, depending on how loud you would like the exhaust to be, either system will fit on a factory car. The resonated exhaust system from Tuning Developments is trackday noise limit friendly which is a big thing to consider for a lot of Ford Focus ST 250 owners who intend on using their car for public trackdays or even competition use.
Non Resonated - £569.00
Resonated -  £599.00
Super Resonated - £619.00
We are currently offering fitting for just £30.00 to Focusstoc Members or alternatively free shipping to mainland UK. Prices quoted are inclusive of VAT.
If you have any questions or queries please do not hesitate to contact me.
