bang for buck, this is the best mod for any TD vehicle. On the Td5 it make a big difference in reducing turbo lag and EGT.

Naks, he's done a "Sound Mod" not the muffler mod...

There wont be a noticeable difference in EGT or spool time.

He's just made it sound nicer for him

well, that's just a waste of time

When I removed the middle silencer from my D2, children ran away scared when I floored it at the lights

Tombie,

What sort of improvment are we talking about,
i have a TD5 Defender and i have been looking at removing the muffler (Centre) but was unsure due to actual improvment that i would expect.

I'm not sure if it makes as much for the fender as they have a cat converter also and the disco's don't... but i could be wrong, i know that it hardly makes and difference to sound.

Also for all, since i have been driving it with the new exhaust, i think it has actually made the spool a tad better.

Not true...

Getting a Cat vehicle was dependant on the build day... I've even seen new 04 vehicles without Cats....

Cats muffle it like mad...

Non Cat vehicles are sweet! A nice growl....

True Tombie2,
As i dont have a cat converter in mine, so the orginal question still stands what performance improvment is expected?

Cheers

Marginal improvement in spool up time and associated throttle response improvement.

Marginal fuel economy improvement is possible (depends on how u drive)

Great Aural improvement
