    I have a question about the rear heat shield in front of the rear bumper, can you drive without it as mine is just trash when i removed it?

    How do you guys do it? is there some other way to protect the heat, can i insulate the exhaust silencer?

    I don't have the original setup anymore but the Nouvalari SS which is a smaller box, like Tubi.

    Running without a heat shield is asking too much from the bumper and paint. I was sick of the tight fit with Capristo exhaust and the stock heat-shield so I made a custom one to protect my OEM heat-shield from damage.

    It’s a rigid alloy heat shield that can withstand and reflect extremely high temperatures. It was massively noticeable to the touch the difference of bumper temperature with and without a shield in place.

    That looks real clean and much better than original.

    Where did you source the heat material for this? i suspect you formed the heat shield to the old original mold to get the correct shape in the end?

    It completely replaced the stock heatshield and does a much better job to boot. I sourced it from an eBay seller it’s DCI XT-1000 rated to 1000 degrees Celsius. It’s dimpled alloy like they use on turbo blankets and Tubi headers.

    It comes as a flat sheet I form rolled it to match the OEM curvature. Added the black line as per OEM. It’s totally reversible when I concours the car I swap back the exhaust and the stock heatshield.

    The sellers ebay ad says 700x320mm, i measured my stock heat shield and it's 700x360mm so it's close.

    Correct it’s a bit shorter but does the job. You can rivet on longer lower brackets if you are so inclined.

    Can the muffler shield be removed/installed without removing the rear bumper?

    I don’t think so, you won’t be able to get to the upper heat shield bolts.
    The rear bumper on the other hand is quite easy to take off (8 bolts and 3 electrical connectors)

    No it won’t come out without the bumper off.

    I love the idea of protecting the rear bumper from excess heat and have seen a number of rear bumpers with spider cracks most likely caused by heat, but wonder if a better heat shield is a bad idea keeping more hot air in the engine bay? what do you think MAD828?

    Put on a challenge grill, the vacuum pulls the hot air out more efficiently.

    You don't need the rear heat shield if you use the challenge grill?

    No I would still have both it just cools the mega hot engine compartment better while moving
