This down pipe is flaring out 3" immediatly after the O2 hoising flange, 3" before and after the flex section. At the end it has an Apext sized flange ( slightly less than 3"). It comes with 2 gaskets, bolts and braket to attach to the block.
I replaced my RSR 95+ GST down pipe with the Megan pipe. Fitment is actually better with the awd pipe. I did cut the pipe since it was to long for my setup and added a true 3" two bolt flange from RRE. Overall I'm really happy with the way this pipe looks and performs. Fitment is PERFECT a c50.
Got this off ebay for $93 + $35 shipping
