UPDATE - My new TI Leo Vince exhaust for the 999

Thanks for posting that question. I meant to post or PM her that same thing but keep forgetting.

The new exhaust system works as well as it sounds.  Mid-range power is noticeably improved.  Removing all three catalytic converters helped, no doubt    It runs well at all speeds with the stock ECU - no pre-ignition ping and the engine runs at the same temperature as before.  Fuel economy is roughly the same; maybe a bit worse but not enough to change my 120 mile range for the low fuel light to come on.  

Having said that, though, I think performance-wise there's room for tuning.  A Power Commander or something like it would make the thing downright dangerous.  So of course I'll add one when I get the cash.

But the main benefit has been in handling - loose ten pounds of stock exhaust and wonderful things happen...

Best mod evah.

I sure do want to hear that 999!

Been working on it, but damn is that last 5 lbs hard to lose. Especially from the back end.

This should help with that:

Well played, sir.
