Went out for a full turbo back exhaust for the 335is. I have used VR Speed Factory (VRSF) for my intercooler, so went with them again.
Very pleased overall. Great quality with smooth bends and tidy welds.
Install is simple, albeit I ran out of time to get the downpipes in. Will get back to them another weekend.
The sound so far is superb. I can barely wait to hear the added noise once the cat-less downpipes are in!
