Exhaust questions (paging peter!)

[peter at thescirocco.com (Peter)]

I'd only replace the cat, if it's bad.

The TT high flow cat is a universal high flow cat, and TT welds a set of 3
bolt flanges to it.

TT no longer makes the A1 DP for the US manifolds, so you'll have to look
for a used one.

Let me know, if you can't find a used DP, I have one on my caged Rabbit. I
installed the DP to get the car to pass the visual emissions check, and it
only has about 20 miles on it.

I'm pretty I need a new cat, because I've been running my car really rich
for a while (better for engine, worse for the cat!).

The exhaust is going to be a 2" aluminized TT with a resonator, and a
Dynomax. (Got it used, I would have bought a stainless, but hey - this was
cheap!)

Should I get some sort of High-flow cat, or stock? What does the high flow
cat come off of, or where can I get a new one. I need reliability and the
ability to pass emissions first, but if there's no downside to going
high-flow besides cost - I might as well do it.

And, is the TT dual downpipe worth it? I have a stock rabbit dual manifold,
downpipe, and an almost new accordian flexy section. I even have both
brackets!
