Tuning Developments Exhaust Components for the Toyota Yaris GR Four!

Item: 3inch Secondary Cat Delete Decat Exhaust Front Pipe (Resonated)

One of many parts which will be coming from Tuning Developments for your GR Yaris! Manufactured here in the UK, with all joints utilising superior flanges and V-Bands 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. 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 front section of exhaust, making install very simple and straight forward, 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 centre 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 Yaris GR owners who intend on using their car for public trackdays or even competition use.

Checkout our Youtube channel here to listen to various sound clips of the exhaust system, showing various different configurations to give you an idea of the different exhaust notes available.

From doing in depth dyno testing, we expect gains to be anything upto 12bhp from fitting this Tuning Developments CAT Back Exhaust System, when in conjunction with our second decat pipe. These items are also listed on our webshop so be sure to check those out too! Discounts are available for a GPF back exhaust system consisting of the GPF Delete, Second Decat pipe and also CAT Back Exhaust from Tuning Developments. Further performance gains will be available with custom tuning which is coming soon through Tuning Developments for your Toyota GR Yaris.
