Exhaust systems for 4.2 litre diesal

[Bigrig]

Form Reg
Fitting an extractor and exhaust system
2.5 inch exhaust works very well and stops that choking feeling
Especially towing caravans
Found also decrease in fuel consumption

Any one else experienced the same results?

Hey mate - a fair bit on the forum regarding exhausts - but like you, I fitted pacemaker extractors and a 2.75" exhaust and definitely had a torque increase and fuel consumption decrease.
