Wish I had a dyno to support my claims, but I'd say the king of racing exhausts would be the Amuse R1000. 9 lbs from the header back (which means a weight savings of 55 lbs or so), 70mm piping, and I'd guess-timate that it makes gains of 10-15hp.

I wouldn't recommend it for a daily driver, though. It's not only one of the lightest and most powerful exhausts... it's also one of the loudest.

 

 

I'd look into this thread before going the JIC route

Far as I know, Veilside teardrop exhaust is the lightest. Comparaing to Amuse R1000s 4.1kg, veilside teardrop is 3kg. But i don't know about the hp gain.

Which means that the Veilside would probably not be the lightest, once you include the weight of the catalytic converter, or even a Stainless Steel testpipe, since the cat weighs about 10 lbs and a stainless steel testpipe weighs 3-5lbs. You could get a titanium test pipe, I believe... but by the time you pay for that, you probably could've just bought the R1000.
