Multiple sound clips of the ARM N63 / N63TU Downpipes installed on a 550i at different speeds and throttle inputs. Car is tuned with an otherwise stock exhaust. For full details please visit: www.armmotorspo... GET ARMED.
Because they have major design problems. Had to practically unweld and remake both DPs so they could fit on my car! And they never post any reviews on their website if it’s bellow 4 stars, which is very bad practice for a seller and performance parts maker
@@DeJonWilson1 I was lucky, I’m really good friends with my mechanic and he only charged me 50$ extra for the 3.5hrs of extra work, all the cuts, welding and practically making new downpipes from their product
Bad idea Done mine 650i got lots of smoke 💨 every time you drive 5min and stop in every traffic light 🚦 and it stink badly Warning ⚠️ don’t do down pipes I Change them back to stock
Your vehicle is damaged. The downpipes did not cause the damage, it only revealed it because stock cats hide the smoke. Engine is damaged - valve stems or piston seals...etc.
Didn’t have any problems with my catless DPs on my 550... Had problems with their intake (the old design, don’t know if it still messes with the MAFs like they used to).
