Hi all, pretty new to this not very mechanical minded. I wanted to decat my focus 1.8tdci but my usual mechanic had it in for wheel bearing other day said he took a look and it needs all sub frame dropping to get to it and is alot of work. Whats peoples history with these and is there a trick to it? Thanks

According to Haynes, there is just an "underfloor brace" which needs unbolting for access. It does not look like a major job, except that many of the bolts will be well rusted in.

I would be most worried about the turbo to cat bolts. They get hottest, and may have been in a long time. If one shears, leaving part in the turbo, it will be a huge headache.

I would not have thought any gains in reduced exhaust backpressure would be significant enough to justify the work & worry. It is not like a naturally aspirated engine where every mBar makes a difference. Under power, the exhaust pressure drop across the turbo will comparable to the boost pressure, ie 1.4Bar.

easy enough to remove, but as peter said you could have problems with the nuts.

So not a case of the wishbone like my guy thinks? Thats fine i will probably take a look at state of bolts and decide whether i dare.

nope, just a bracing bar, ive removed a few to get at the turbo, and took all of 15 mins to get off, admittingly i used a ramp so that made it alot easier to work on

Got a ramp so that's sorted just not the one doing most of the work will be a friend but he was making out as if it was difficult just wanted to prove him wrong lol
