Cat Back Exhaust

This part does not affect the base vehicle warranty.

mountune Performance are pleased to announce the addition of a stainless steel Cat Back Exhaust system for both pre and post-facelift mk6 Fiesta ST models.

Like all mountune Performance products, our mk6 Fiesta ST cat back exhaust can be fitted and used without fear of affecting your existing Ford warranty, and comes with its own 12-month / 12,000 mile parts and labour warranty too. In addition, there is a lifetime parts-only warranty against any manufacturing defects, when retained by the original owner, and fitted to the original vehicle.

The mk6 Fiesta ST cat back exhaust features a single 3.5" round tailpipe with "mountune Performance" etching, and is the perfect accompaniment to the mountune CAIS, or for standard cars wanting the 'mountune' look and sound.

The cat back exhaust comes with the required clamps and adaptor pipe to fit the OE exhaust if required.

Please note: check to ensure you select the correct fitment for your car; either Pre-facelift, or Post-facelift.

Post-facelift cars are easily denoted by the 'bug' eye addition on the headlights / tail lights, and also the soft touch dash / grey clocks.

A trade-up value of £300 will be deducted from any future MP165 or MP185 mountune full kit upgrades, providing the car is brought to mountune HQ in Essex to ensure correct installation of the cat-back, prior to the core upgrade being fitted.

    Great Exhaust!

    Installation was simple and straight forward. The exhaust is very quiet and adds noticeable mid range torque. Overall, very satisfied!

    Cat Back System and CAIS

    Purchased the Cat Back system along with the CAIS and they make a perfect pair. The exhaust gives a good throaty note when you put the hammer down and when you get above 3000 revs it really comes alive. There's a good amount of pop on the overrun once it's up to temperature but nothing too loud and annoying, just the right satisfying amount. When you are cruising at motorway speeds it's not much louder than standard which is exactly what you want on a daily driver. It's the perfect mix of sport and comfort. The 3.5" pipe looks fantastic, feels very well made and the Mountune etching tops it off. Both parts purchased and delivered within 48 hours as well. Overall a solid product and a very happy customer!

    The exhaust sounds brilliant and looks fantastic. Great sound matched with the CAIS. Would definitely recommend this product to anyone who's considering it.
