Thread: Disco 2A TD5 exhaust mods

Drop centre box, replace with hot dog to avoid drone.
No need to change size.

My TD5 goes great with standard exhaust, I have had it chipped, boost box & larger intercooler, also variable vane turbo. Still get 10l/100klm too.
I would attend to the exhaust last.

The 2.5” diameter of the standard exhaust is fine for the power levels of the Td5 even when hotted up. The two main restrictions are the main muffler which can be easily replaced with a straight through high flow unit and the flexible joint in the front pipe which has a smaller internal diameter than the exhaust pipe and can be replaced with a larger one to keep a constant diameter of the exhaust system. Also the cat converter, for later emission standard vehicles, which can be replaced with a high flow unit or perhaps removed if the vehicle is off road only... Beyond that your just throwing away money for nothing in the exhaust system - rather start with the intercooler and turbo options.

If noise is a concern a hot dog can be put in the cat converter position (if no cat converter is fitted) and in the tailpipe to reduce.

Once you go big turbo then often a 3” is required.

thanks, guys I might just get rid of the flexable hose and the cat, before the remap.
