Exhaust size...was "Where to get.."
Posted: Fri Apr 05, 2002 2:14 pm
Well, 2.5" of 3" is an improvement over the stock setup, so either
is better than stock. I think everyone here can agree that the
original must go. If you have a 3" downpipe and any of the stock
piping left, you're not getting much of the advantage that the
larger DP affords. Replace anything smaller than 2.5" soon, rust
or not.
As for the torque, the low-compression nature of the turbo'd
engines doesn't have much on the low end (<2500) anyway, so
any possible drop wouldn't be noticeable. What you will gain is
faster spool-up, so boost will come in faster. Any loss of torque
will be brief.
In summary, 2.5" at least, 3" if you can find a place good enough
to fit it.

u drive like a nutter, going up and down the gears all the time,
then it doesn't matter if you lose a little bit of low end torque
because you wont even notice it. If, like me, you spend a lot of
time in the city then, ok, it could mean a bit more dropping a gear
(assuming you have an MT). However, the chances are if you
drive around town mostly (again like myself) then there's little
chance of a short blast anyway. Nothing much really happens
south of 3000rpm anyway.

swapping the stock blower for a beefier unit. I recently did a
change from stock diameter exhaust to a catless (was catless to
start with) 3 inch throughout and I can't say I've noticed any
noticable drop in low end torque. In fact, spool up has improved
marginally and general drivability has improved because of the
significantly increased flow. The turbine makes a much louder
noise now and top end is incredibly smooth (car used to vibrate
madly at sustained "high speeds"). Porting the stock manifold
has probably contributed too.

that's my vote. Others with differing views/experiences?
