TTI and/or GMR Turbo Kit with 2 CATs, is it possible? Is it possible to run 2 CATs with a TTI Single Turbo Kit or the GMR Speed Single Turbo kit and still make 525RWHP with heads, cam, UD pulley, Ported TB & EWP with no problems or damage to the CATs?
This would be more for a street driven vehicle with maybe 5-10 passes down the track a year.

Still don't know why you would want 2...but ya you could probably do it with one. But you would need to replace it often, it will take alot of abuse. As long as the turbo isn't remote mounted (in the rear) then you can technically throw as many cats on it as you want. Just don't expect your turbo to like it. You might end up needing to rebuild alot more often due to the crazy back pressure.

I know the base TTI kit comes with a Cat but using a t-76 along with head and cam, I'm sure that cat won't hold up and flow enough..
Turbos don't like back pressure, that's why I was thinking having 2 Cats after the downpipe, basically going from the downpipe, 'Y' it to the 2 Cats and then 'Y' it back to 1 pipe again to your cat back. Magnaflow has new Cats that flow around 550 CFM each and they are very small in size. They should fit underneath the car.
Yeah I know Columbus doesn't have Echeck, I'm looking at getting rid of the exhaust smell at idle and low cruising speeds.
I'm thinking technically it should work, but how hard are turbo systems on Cats? You really don't read about people on this board using Cats with turbo kits.

You said it yourself, turbo's don't like backpressure. So doesn't matter where you put the cat after the turbo, it will still create backpressure. There is no right answer here, if you want to do it you CAN. But should you? That is a different question...
