RRE DP in 2g with T-25 waste of $$$

[96TalonAWD]

I just bought and install a RRE DP 2.5" on bend and 3" after flex replaces the cat converter too with a 2.5" custom cat-back. Some friends say that im losing power because the T-25 it doesn make enough back pressure? It this true

you are not losing power due to your exhaust being too big. for a turbo car, you want 0 pressure in the exhaust after the turbo (the pressure differential spins the turbine). You are losing power however with that 2.5" catback. you are causing your exhaust to 'bottleneck' so it swirls (with the hard 90deg bend) and is most likely more restrictive than the stock was due to so much loss in exhaust velocity.

on the t25 yes you are lossing a little low end torque but its not like this massive power loss. Remember Best Exhaust for a turbo car is No exhaust.
