Thread: Defender TD5 Exhuast

3.5" is heading into doof-doof territory

Don't think you're going to gain much on a TD5 past 3", but then I am a farmer so you'd better talk to your local exhaust shop.....

Are you talking about removing the whole exhaust and replacing with a 3" or 3.5" pipe with no silencers?

If so thats going to be NOISY!

I have a straight through (CAT removed) front pipe and mid section on the 110 but have left the rear section standard so it still has the silencer. Its still pretty noisy when I press the loud pedal hard.

If you are replacing the whole lot, then 3.5" will be a bit better than 3". If your just replacing a section, then keep it as close to the original diameter as possible.

Regards,
Jon

3.5" wont help at all....

3" is the max... Turbo outlet is just under 3", anything larger is a waste.


"Lara" is 3" from the turbo back... Runs better with the 3" vortex than straight pipe.

exacterly what he said! but a bit of what john said too.
the turbo outlet size is 2 3/4, you can fit 3'' on it but its a bit of a process. im 3'' straight through to a vortex and then from the diff back i kept the OE 2 3/4 to keep the gass speed up. it sounds great!
