    Hard Pipe Upgrade - well worth it.

    Ordered just the pipe due to the silicon hoses being unavailable. It’s a surprisingly simple (appearance) piece of kit, as described on the website; well presented as you expect from Mountune. The weight difference is very noticeable as soon as you remove the original Ford pipe, the Mountune upgrade being much lighter, and the design apparently much simpler - no ‘baffle-collar’ as per the original part, just a straight-through pipe. Fitting is straight forward; car onto axle stands, under tray removed then 2 hose clips (7mm hex or screwdriver), a 10mm bolt and a 13mm nut. All done in circa 30 mins. I was unsure whether I would notice the difference, buying the pipe as prep for potential MR300 however very pleasingly there is an instantly recognisable difference; so the 39% flow increase as per the website description. The throttle feels lighter which I expect is actually the improved responsiveness due to the increased airflow; the car spools-up quicker so despite the lack of silicon hoses (which moreso give a longevity benefit I expect?) fitting the hard pipe alone at this stage does result in a noticeable change; and added another smile! Well worth the reasonable price; straight forward to fit. Thank you Mountune.

    Fantastic Value for Money

    This product made a huge difference, the reviews were spot on. Definitely more power and a bit extra spooly noises from the turbo made this product fantastic value for money. 110% worth getting
