    Build quality was superb, and a great kit from standard. The car pulls so much better than before and the intake noise is lovely, the only reason I am giving it 4 stars instead of 5 is the only part that let's it down is the cat back exhaust. Even though the build quality of the exhaust is brilliant and it looks lovely on the car, it sounds the same as the standered exhaust. To me this really let's it down, not that I wanted an extremely loud exhaust but I wanted to be able to hear it. The central box on the exhaust is massive and removes any noise coming out. It would benefit with the silencer being half the size. Overall great bit of kit but with the money I spent on it I would of liked it to sound how it goes

    MR300

    I got the ST as an MP275 with the mountune Cat back exhaust which was an enjoyable car to drive there were a few things i didnt like which were the symposer and the wheel hop which slapped my wrist everytime i really wanted to use the power from the MP275 so i added the roll restrictor and the symposer delete and also the recirc valve as the standard plastic unit isnt the best and i loved the car it was able to use the full MP275 and at that point i was set that it would be even better with the MR300 so i set about getting the needed hardware and accessport with the MR300 and what a transformation it is the mid range punch is much better very pleased with the performance and the handling is further upgraded with the mountune sports spring kit which works very well with the MR300 great upgrades

    What a thrill

    I bought my ST MK3 MR 300 a few days ago and It is truly amazing. It's like being in a rocket, the car is very fast. The tourqe is massive and the power makes me smile all the way to the red line. No mather what gear or rpm the power is there, all the time. The exhaust is very silent on the Highway, no drone or anyting like that. This kit is a "must have" for all ST MK3-owners in the world. Stefan (Sweden)
