    68440 is rated 4.3 out of 5 by 3.
    Rated 4 out of 5 by from C4 headers Very nice fit for affordable headers. I had to dimple and bend some tubes to clear spark plugs and header bolts. Clearance is tight in areas but works. The included shorty header bolts actually worked better than the ARP studs I purchased. The ball/socket collector is a pain and caused some issues.

    Rated 4 out of 5 by from Good bang for the buck The only issue I had was I had to dent one of the primary pipes a little in order to get one of the spark plugs in. Other than that they sound and look good.
