Better than factory by far. I have the turbo inlet and IC pipes. I won an auction and got them cheeper than the buy it now price so I didn't do too bad.
Having said that, the downside: worm clamps!?! WTF man...worthless, shipping = forever, and you have to contact them every week to make sure they even remember they sold you stuff. On the upside: Welded on bov flange of your choice, 4-ply couplers, snug fitment with oem bends.
Because they forgot my order almost completly the sent me a free upper rad hardpipe that leaked out of the weld....I guess it's the thought that counts on that one. :dunno:
