Turbo pipes in atmosphere or back into exhaust?
How many of you are running your turbo pipes into the atmosphere versus plumbing it back into the exhast system. I've run it both ways and definitely prefer the latter but did not know how much HP and TQE I was losing between 3-5K RPM on the steet?

On the same motor with t4 turbos and 3" downpipes, it lost 1 rwhp on back to back dyno runs.
IMHO, recirculate them and have a cleaner, better sounding kit with a negligible amount of performance loss (depending on the setup of course)

Thanks Wade, I would certainly have to agree with you. I'm running an HP TT Kit with 57mm turbos dumped into 2.5" exhaust 10 lbs boost on my forged 347 C5. How about cats, will they hold up under the heat and what are the best ones (round to fit in my exhaust tunnel)?
