The whole system, with cats, offroad pipes & Y-pipe:

One of the reasons I chose the FLP's was for ground clearance. There
just isn't much room under these cars and I thought the FLP's were a
pretty good compromise--you do lose more ground clearance than with a
set of shorties, but not all that much. And I didn't want any damn
Here is the most likely point of contact:
That's the driver's side, well after the header. The header itself tucks up very well with no ground clearance loss. But GM never intended exhaust to run on this side of the car--and it shows. The clearance here could be helped by running a section of oval pipe (and getting rid of the cat, of course) for that section of the Y-Pipe. I'm only lowered a little less than 3/4" in front so it hasn't yet been a problem for me--but I haven't gone out of my way looking for speedbumps either.
Here's a shot from the front:
As you can see, the passenger's side header hangs down pretty low. But that's the lowest point on that side and since it's farther forward I don't think it's as likely to drag on speedbumps, etc. From the header back, the exhaust is actually higher than stock since GM provided the room for it.
Here's a shot from the back that shows this pretty well:
Now for the cat-back:
Mufflex 3 1/2" catback with Spintech muffler:
A Borla XR-1 Racing
Muffler. The quality difference isn't even funny,
they aren't even in the same class. While the Spintech looks like it
was made in sombody's garage, the Borla looks like it was made by pros.
The inlet and outlet were actually round and the correct size. Daily
driving the thing in Seattle, it's nice to know it's 304 Stainless.
I've already rusted through one 409 stainless SLP muffler since I've
The Borla is obviously a straight through design while the Spintech is not. Something else rather notable, (Mike will like this) the Borla weighs 1/2 what the Spintech does.
Here's the end result:
Given the straight-through design of the Borla, I had to move the exhaust hanger on the driver's side:
