I have a 2002 2.0 tdci with a map on it. My questions are does my car have a dpf? Could I get away with a de-cat pipe even at mot time and would it increase performance and same goes for the egr delete? If its a yes would I need my map tweeking? Also I like the thought of a bigger intercooler is there a oe option or is it a eBay job?

Your Mondeo does not have a DPF, just a small passive cat (no elecrical connections/ sensors) it can be removed without issues and replaced with a decat pipe

As far as the emmisions test is concerned, only the smoke is measured, the cat can be removed and the car can still pass the smoke test, it may actually help it pass, as the soot can build up on the surface of the cat

There is a visual inspection to determine if a cat is fitted, and one should be fitted, if one was fitted as standard, you cannot see if one is fitted or not from under the car, because of the undertray, there is a heatshield on top and an engine cover, and it is very difficult to see if one is fitted or not on top, the MOT inspector is not allowed to remove any covers

The decat helps the flow (scavenging) out of the turbo turbine, this helps it spool up quicker, improving throttle response and reducing lag

On a MK3 diesel, it is the exhaust back box that is the main restriction in the exhaust system, there is very little point in de-catting the car without replacing the back- box 1st, (the middle silencer, if fitted, is not that restrictive as it is a "straight through" type)

The rest of the exhaust is not bad, at 2-1/4" (approx 57mm) its big enough for the sort of power/ torque you are likely to get (mine is 160+Hp with the decat and straight-through back-box box otherwise stock, apart from the decat and downpipe being heatwrapped and the downpipe/ flexi is "gas flowed")

The decat and the back box delete can significantly increase the power, and work with other mods, the engne should rev quicker, with much better throttle response and less lag

It may need a remap tweak to make the most out of it but will work without one, an ECU reset may help and costs nothing

An EGR delete can help inctease power a bit, but not as much as the exhaust would or the Remap did, so more of a subtle improvement but definately an improvement

You may be better off with the stock intercooler, an aftermarket cooler may just increase lag because of the increased internal volume, the stock cooler has 2-1/4" in/out - bigger than a Focus ST225(2") the stock cooler has a small mass so has a lo thermal inertia - this is good on a diesel, it is not "masked" by the bumper, many aftermarket intercoolers are, this is not good

On top of this, i have performance figures from a Mk3 with stock, bluefin only, bluefin/decat/massive artec intercooler, the bluefin only outperformed the one with the decat+intercooler, probably due to the additional lag the intercooler introduces

You can read my build thread for more tuning ideas

no your car doesnt have a DPF and very unliekly that your car will get away with a decat pipe with the new rules DPFs and decat must be there is fitted originaly now.
