I  was underwhelmed w the performance difference and wondered
about all the  positive info I had read on "uncorking" the 
exhaust on these little  diesels.  
Just recently I had occasion to put in a new timing  belt and
water pump.  After I had set the timing and went for a  drive
the difference I felt was enormous.  It was like a whole  new
engine in there!  I can only surmise that the timing was off
a  bit, perhaps due to a stretched belt?  Having never set the
timing  before on this engine I can't really say. But I am way 
pleased w how the  truck now performs and sounds.  It was a bit 
pricey but I'm now a big  fan of techtonics exhaust systems.  
One last note is that the 2"  exhaust actually measures one 
and 7/8" I.D.



Difference on a TD can be huge.  On my 1.5 Rabbit, 2" back  really opened 
the top end and extended the torque curve but not much otherwise, maybe  a  
little mpg.  2 1/4 on the 1.6 pickup did nothing through most of the  range 
but 
bottom end was unstallable!  Didn't gain any mpg as I recall.   Jake had a 
2" 
Techtonics on his 1.6 TD Rabbit and I finally convinced him it needed  
2.5".  
He welded up a 2.5" mandrel bent system and was hugely impressed with 
the improvement.  He'd been previously impressed with what the 2"  system 
did for him.  His 2.5 went from the turbo rather than just the  
spring-clamp 
donut as the 2" did.  
When we put the TD in the pickup, it  never got anything but 2.5 from the 
turbo back so I couldn't compare.
