Is it loud? I want to install headers on my M54B30 because the stock cats are really restrictive, but I don't want my car to be loud and sound raspy like the M3
It definitely increases the volume, but if you have a stock exhaust for the rest, it is not a huge increase and only really heard when you're really getting into the throttle. Cruising with a stock exhaust, negligible.
Unfortunately it looks like trader nas got greedy and is now selling them for 350. Might need to try some other merchants, that sucks. Shouldn't spend more than 160 on them shipped
Do straight pipes with the x pipes. One x pipe per header, so that's 2. It will increase performance by a little and also give it a deeper tone sounds amazing look up a few videos
Do you get a engine light for the o2 censors
Coding this out it very cheap just do that, you have to remove the SAP which will need coding anyways and it’s only $100
other than epidemic sound, can you feel any power increase?
It’s way lighter and with the secondary air pump delete makes it even less. So yeah but it’s not insane.
Did it fit or did you have to cut off the bung and weld it further down
