My 5ktq has a 3 inch exhaust from the downpipe back, including a 3 inch cat=
.  I Got away with no flat spots or crimps anywhere by removing/modifying t=
hat drive shaft brace/subframe piece just behind the cat.  The car has a ch=
ambered "warlock" muffler that is a flowmaster copy.  Overall the exhaust m=
ade a huge difference, and I would recommend going with a 3 inch over 2.5 i=
nch exhaust.  I had mine bent at a local INDEPENDENT muffler shop for about=
 $200 from the dp back including the muffler.

I have H&R 200 20V springs with Boge Progas in the front and Boge sport in =
the rear.  As far as I can tell, this combination really shows how stiff th=
e unibody is not.  Progas shocks have a "load zone" that is REALLY firm. Th=
e drop in the springs puts the car in the load zone all the time.  The rear=
 is a little underdamped.  Most of my suspension travel is coming from my t=
ires which are 60 series. This is not ideal, ride is very rough.  But the c=
ar tries very hard to avoid pitching and rolling at speed.  At the limit th=
e car is very well behaved for its size.
