Everything you need to install our exclusive active V8 dual exhaust system on your ND. All of these parts are gorgeous polished stainless steel. The exhaust (other than the cats) carries a lifetime warranty. It's all tucked up tightly under the body and designed to use existing space in the tunnel and around the large V8 diff. Made in the USA!
Starting at the heads, we have custom headers built for this application. Built for us by PPE, they have a 1.75" primary diameter. These may fit on other applications.
The exhaust portion includes two ceramic core catalytic converters, a crossover pipe and 2.5" piping. The mufflers are custom-built and include vacuum-actuated bypasses. That's right, at full throttle this thing is basically straight piped but is civil when you need it to be. It's a glorious noise.
The completion kit includes a number of parts that we strongly recommend but are not necessarily required. That includes the center brace to support the exhaust (if you don't buy one, you'll need to build one), poly exhaust hangers, DEI heat shielding, plumbing for the bypasses and the electronics needed to connect them to a CAN control.
The diffuser hides the cutout for the stock exhaust and gives your center exit a nice finished look. It's not really functional as an aerodynamic device.
All parts other than the diffuser should be compatible with the Fiat 124.
Please note that the parts in the video have Swain ceramic coating. This is not standard - if you would like the Swain coating, we recommend you deal with Swain directly.
