Thoughts on aftermarket exhaust manifold and riser parts

[CurrentObsession]

Looks like I may need to replace exhaust parts on my 1999 5.7L BIII Rinker. I noticed that there are several aftermarket players out there. Any good/bad/indifferent experiences out there? Will be running fresh water only.

Brands:

Osco
Barr
Sierra
Aqua Power
GLM

Don't buy GLM. Lots of horror stories here on the forums. I run sierras without any problems. Other people on this site say good things about Barr and Osco also. Don't know much about Aqua power. Whichever brand you buy, make sure you use the Mercruiser riser gaskets.
