exhaust question

[futuretgp'er]

ok so im a complete turbo newbie and im not sure of the exhaust configuration...sad i know but could someone give me a list of exhaust components on the tgp in order.
ex. headers to y pipe to cat to muffler...to be simple

also pipe diameters would be cool?

Manifolds -> Crossover -> Turbo -> Downpipe -> Cat. Converter -> Y-pipe -> Mufflers -> Tips

The piping is 2.5" O.D. I believe...at least it was on my first TGP when I replaced the converter. The second TGP I bought doesn't have a converter or mufflers, so I shouldn't have to mess with anything on it.  8)

ok thanks,
now is this necessary as an adapter  for the downpipe replacement made by redzmonte??

if not what is its function or what makes it better than what is already on there
thanks for helping me with my ignorant questioning guys

might ask Shane himself.  he didn't post much in the way of details but i would like to know too.

that adapter from ATP just bolts straight to the turbine discharge side of the turbo and has a 3" outlet which might make producing a 3" downpipe easier.  you probably could just cut the first section of the original downpipe off and re-use that, but it's not 3" in diameter either.

now if you were to upgrade the turbo to a T3, i'm not really sure what else you would use beside a T3 V-band adapter, since you couldn't use the original downpipe at all.

Cast manifolds have a 1.75" Outlet
x-over is 1.75"
Turbo to downpipe is 2.25"
Downpipe to Catback is 2.25"
Catback to Y is 2.25"
Yback to mufflers i think is dual 2" or dual 1.75"

all sizes are OD. and the majority of the piping from the manifolds back is press bent. I am not sure about the turbo to downpipe, but most likely press bent.
