    300121 is rated 3.0 out of 5 by 6.
    Rated 5 out of 5 by from Fit great!! Jegs headers fit fantastic and look just as good. After fighting fitment issues with Doug’s Headers that cost three times as much, Jegs came through. Phenomenal, thanks again Jegs!!

    Rated 5 out of 5 by from jegs premium pontiac ceramic headers headers fit fine not to low not to hard about 3.5 hours and it came with everything needed to install
    Date published: 2015-12-04
    Rated 4 out of 5 by from Great looking headers for the money Look great and love the thick flange. Cant speak for fitment as I haven’t installed them yet but looks like they should be alright. Really nice finish. Jegs, did forget my collectors and the gaskets arrived broken but a simple phone call to Jegs and they made it right. I think I got sent someone elses returned headers as even the box was pieced and taped together unlike a factory sealed package.

    Rated 2 out of 5 by from headers look great but they do not fit a 1976 trans am passenger side was almost to tight to work and drivers side i had to cut #1 runner off and refab and bend new tube to get to clear crossmember of suspension i guess the rest of these comments are lucky in there fitment

    Rated 1 out of 5 by from Does not fit 1979 Grand Prix I am giving this product a POOR review because it says it's for 1964-81 Pontiac Passenger Car (326-455 C.I.). My car is a 1979 Pontiac Grand Prix and installing a 1974 Pontiac 400. We put the headers on the 400 (which bolted on good but horrible exhaust gasket, had to buy an aftermarket gasket). We dropped the motor in and seen that on the passenger side one tube hits the A-Arm and drivers side one tube hits the A-Arm and another tube hits the firewall. Not even close to fit! Good looking product though! Definitely need to change the years. Not made for G-Body cars!

    Rated 1 out of 5 by from Don't fit I ordered these to fit a 64 GTO. The passenger side was fine , but the drivers side was not even close to fitting. They hit the cross member with the engine still 6 inches off the mount. The second set was the same.

    Do these headers interfere with the oil filter on a 1976 firebird with a 400 pontiac engine.? Can the oil filter be removed normally ?

    Asked by: 1572
    The only notes we have on this header is that a 1975 lemans may have some minor clearance issues that can be fixed.
