Title: BBC exaust
Post by: barracudajet on February 09, 2016, 06:51:21 PM

Would I see any more performance by replacing my cast iron Barr exaust with aluminum indmar exaust manifolds. Both 4". One Barr has a outside crack that just shows rust. No leak. Stock marine power 454. Thanks.

Are the Indmars logs and snails?

If they are, probably no gain in performance, But definitely a weight savings, usually unnoticeable in a heavy cruiser.
