Thread: Improving TD5 performance. exhaust query

After collecting it, I had 900K's to test drive it home.
I found no real increase in engine noise inside car, minimal "drone" that some have referred to after removing muffler.
Car does perform better than my other TD5 D2, and climbed highway over escarpment with ease.
have since done 3000k's in past week and find that fuel consumption is 10L/100k at average 110-120kph. (And vehicle has 235 tyres so running slightly smaller diameter than usual, which I am changing later in week.
Have had to overtake semis on road and find that vehicle can hit 140kph pretty quickly.

how are the EGT’s especially pulling over the range and overtaking?.

Thread bump - interested in the answer to this question also. @vbrab - anything you can report about the impact of these upgrades on EGT?
