Thread: 3" exhaust for "Baldrick" TD5 Defender

Overboost and overspeeding are common with 3". But does depend on the muffler.

The aftermarket turbo guys won't warranty the units with a 3" pipe.

Whats optimum for a 300 ? I've been wanting to drop the resonator and muffler on my 130 and run a straight pipe.

A 4BD1T.....


I'd drop the centre muffler and leave the resonator, The standard system isn't too restrictive really for a 300Tdi, unless running a VNT and lots of tweaks...

A 3inch mandrel bent system with one muffler (taipan xp) made a huge difference to my 300tdi 110. the fuel was tuned at the same time.

Sclarke, do you have a EGT gauge? if so is it pre or post turbo?

Hey Pat who online sells the kits? Very keen on that idea.

No egt. Some cars I prefer not to know what goes on. It's more a worry than a security
I just like an accurate temp gauge and a oil light that works. Lol
I'm my past rally cars I've had oil temps and volts and amps and gearbox temps ect. It's all destracting. If it's out of the recommended range you start to worry. I prefer to not worry about a higher than normal reading for 10 mins. I may fit an egt, but as mine in exhaust and chipped, if it's high on normal driving. Not much you can do. I don't tow so it's not working hard. The past 300tdi I had I had a egt and fueled up alot. It never hit 650 unless I was flogging it up a very long hill like the one from dargo to talbotville. That tests all cars temps. 15 min constant climb. My last defender could not climb it in 3rd high. It is not kind on cars.

650 is pretty high if the probe is post turbo.....

cheers,

Do a google search or better yet go on ebay,in the performance mods section you can buy just about anything.The Tdi exhaust is simple so should be a sinch to make. Pat

Just time, and some 10mm rod for the new hangers, and a transition for the 2.5" dump to 3" pipe, and some 3" flanges and gaskets and a lot of welding

There's a thread here somewhere of my 3" system on a Tdi and i wouldn't say it was simple, it took a fair bit of time.
