it really feels completely different running the stock tune versus the stage 2+, with all my supporting parts my 340 is so much faster

Love it

With my particular choice of coils, (oem s55), they work great! No stumble or missfire

Great product fast service thanks again for the excellent customer service

easy install and with my downpipes its just crazy fast

the tune install was so easy, the 340 feels completely different

it took a little bit to get my set, but so worth it! the colour in the pigments are just too nice

Just PERFECT! The car sounds fantastic, the tone that the exhaust provides is just glorious and its definitely loud when the valves are open. The valve system works and the car goes back to stock when they close

installation wasn't too bad, cant believe how light it is compared to the oem trunk. so worth it

super different from stock i did the stage 2+ with my bolt ons and its way faster.

Does what it's supposed to do!
