Quick Question
#4
it has nothing to do with weight... it's that the catback is on hangers attached to the car body which doesn't torque with the engine. so basically everytime you rev or load the engine and it rocks to the side you are torque loading you downpipe. Not so stellar. If you don't want to pay for or use a flex section just put a bracket in that bolts to your bellhousing (like stock) and you won't over stress the turbo/manifold.
