***SOLD***
I am selling one month old (500 miles on it) AR resonated catless downpipe for 135i/335i (no XI).
This downpipe has built in vibrant resonator to reduce rasp and drone.

I couldn't get used to catless smell, so I swapped it with AR catted downpipe.
Downpipe is in very good condition since I only used it one month.
I have it available now for $850 local pickup or $870 shipped.
This package includes BRAND NEW AR Bomb Proof gaskets(2) and AR Extreame Exhaust Hardware Kit (4 bolts, 4 nuts, and 8 washers).
