i would go on a limb and say regardless of the manufacturer - they will all make about the same power within 1 hp and 1 ft lb torque - it is just an axle back section so you are taking into account changes in pipe routing and muffler flow and of course sound on the different designs - the car is bone stock other than changing out the axle backs - if the car had some more modifications done to it different axle backs might excel a bit more but in the state the car is in i don't really think it would matter

Of course NOT!!!
TRD and GReddy are two different companies.
and the structure of the exhaust is different... maybe in a certain way they look alike, but they are different.

ok seriuosly people stop bumping a thread from 2005 with no info since then. I believe this company has gone under plus nobody is gonna do tests like this anymore with so many things on the market. Just read reviews cause thats all your gonna get.
