Warped exhaust manifold
Hi - I've managed to warp mine 🙈
A question for you .......
How much would performance be affected by a blowing manifold ?
I'm changing mine but just wondered what difference it would make by blowing ? I.e. Would the sensors detect less gas & hence the ecu supplying different fuel mix ?
Would it affect the turbo performance in any way ?
Just wondered lol

Less exhaust gas going through the turbo, slower spool less power.

Plus after time the gasses will begin to erode the metal around where the leak is...

Best get it sorted ASAP.

Good luck mark. And remember to torque the nuts up in the correct order - Middle to outside.
