    PCE316.1061 - Speedmaster Exhaust Headers is rated 3.0 out of 5 by 2.
    Rated 3 out of 5 by from fit is ok but... The 4 and 3 cyl will need a 45 deg plug wire to avoid the pipe. I got away with the stock boots on all the other plugs. The down pipes flow with the angle of the block. That's nice for a tight fit but the flange doesn't flair back to vertical like most shorty center dumps. makes running the down pipe a pain. The outlet flange is not 2.5 inches. It is 2.36 inches. no clue what that actually fits but it isn't anything I have ever worked with. It wasn't a big deal in my case because the entire outlet had to be cut off and a 22.5 welded on for the down pipe.

    Rated 3 out of 5 by from I will make them work Stock spark plugs will not work, 2 of the banks the plug wire hits the header. I will try and find some plugs that have an angle. Cant beat the price, they look nice, just wish I ordered these before I did the spark plugs. If I get them working, I would recommend them and also recommend proper plugs.
