BMW F80/F82/F83 M3/M4 Equal Length Valved Sport Exhaust System

good product and great service

the valvetronic equal lengh first on my 2016 F80 , the bolt positions on my mid pipe can't be aligned with my downpipe, called Valvetronic and they quickly sent out the replacement . after putting the new set on, it fits perfectly , like the tone , when the valve is close, just slightly louder than the OE one, when valve is opend , it's loud and pops ! but no drone while crusing on highway ! very satisfied with the result it turns out. would prefer to have 4" outlet tips than the 3. 5" though

AMAZING!

This exhaust will definitely have you smiling from ear to ear, the car is so much louder and with the click of a button can be quieter than stock! Definitely worth every dollar!

F80 M3 CS EXHAUST

This exhaust I read great things and watched plenty of videos about it so I decided to purchase it and I’ve had it on for about a week now and it’s the best purchase I’ve ever made. Made the car way better with the driving experience and I couldn’t ask for a better exhaust. Hope this exhaust lasts for as long as I keep this car and hopefully no issues but I would 💯 percent recommend this exhaust to every F8X owner as I think it’s the best exhaust on the market for sure.
