    11142 is rated 3.0 out of 5 by 2.
    Rated 1 out of 5 by from Poor Fitment I bought the specific headers for my truck that is supposed to bolt up to the factory exhaust. Not even close. The driver side was 3" off and the passenger side is so close to the block i had to cut part of the trans housing to get the collector to clear. And i can't use the factory plug wires, cyl 3, 4 and 5 need short 45 degree boots.
