Easy question, lazy questioner.

What is the minimum radius of exhaust bend that won’t effect tuning?

Decker, Michael


Good question. I don't know the answer. Most people using tubing
bends which are about 2.5 inch center line radius minimum as I recall.

The stock manifolds are sharper bends. Particularly the turbo manifolds.
