Mrbaldhead 10 Posted June 20, 2016 So so so, I have ditched my cone shape K&N filter for a carbon BMC CDA. First impressions..... the BMC delivers smoother and more reactive/responsive power BUT it is about 40% quieter on the exhaust note but about 50% louder on air intake (Induction noise). Has anyone ever noticed a decrease in exhaust noise after fitting a BMC as I do prefer a slightly louder tone! Ian Quote Share this post Link to post Share on other sites
stuarttaylor37 13 Posted June 20, 2016 I went from K&N to BMC and found the same as you but I prefer it tbh, I found the K&N too loud and annoying. With the BMC you only get it when you want it Quote Share this post Link to post Share on other sites
