Default Quick Question

Do you guys normally run a flex section on your downpipe? I noticed the factory exhaust doesn't have one and that would save me $50.

I was wondering this too. I see some do and some don't. I know some do because it helps take the load off the manifold, that is, the weight of the turbo and exhaust pulling down on it.

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.

I have one at the end of my downpipe. I would recommend using one.

They are also helpful in DIY exhausts that might not be perfectly aligned. They give you a little "wiggle room" when it comes to fitment.

If my BEGI DP didn't have the flex section it wouldn't have fit.
