Project FD RX7 Restomod: Part 27 – Fabricating the Exhaust with Vibrant Performance and SP Mufflers

We had amazing success with Heatshield Products in our Project Viper, using their HP StickyShield on the firewall and transmission tunnel, and the HeatShield Armor on the exhaust pipes themselves.  We used the same formula on Project FD RX-7 Restomod with HP StickyShield in Part-23.

We covered the top of our downpipe in ½” thick HeatShield Products Armor and secured it with thermal ties.

Mounted in the car, there is very little exposed exhaust manifolds, tubes, or downpipes.  All of this thermal management will improve our turbo’s performance, make components live longer, and make it easier to keep the cabin cool thanks to the Heatshield Products HP StickyShield on the firewall.  We are also using the JP3 FD3S 13B-REW Lower Intake Manifold (LIM) Block Off Plate to keep debris and random falling bolts out of our engine.

We use more HeatShield Armor on the downpipe to further keep the exhaust energy up and heat from soaking the chassis and drivers compartment.

With all of the heat shielding installed, the exhaust system was now complete.  We installed aerospace-grade stainless steel -4AN fittings from Brown and Miller Racing Solutions to our Turbosmart wastegates and 3D printed some caps to protect them until we could make the lines.
