I have replaced the header on the driver side with a manifold 2463107 when I had to replace the starter.
I have a passenger manifold 2532464 to go on that is cleaned are ready to install.
What would it be like if I left it with manifold on the drivers side and the header on the passenger side ?
I'm guessing different exhaust pulses , maybe smoothness , idle etc.
Have ordered TTI head pipes today.
