sbc exhaust system

[gnbrian]

I would like to replace the exh manifolds and risers on my '85 Classic 290 Volvo. Are there any upgrades available that are worthy for a stock motor? If not,are Osco replacements okay ,boat is used in sunny South Florida. Where are the best deals and tech support available. Thanks in advance

If this is a Chevy go Stainless Marine. Osco ate a good quality cast iron exhaust, at least as good as stock. they have been around over 50 years. Not a high performance system. Osco arn't pretty but work. they make an exhaust for every motor made, like the 426 Hemi, 389 Pontiac, and I saw one on a old 272 Ford back in the 60's

Kodiak makes an aluminum center-rise manifold with individual exhaust-runners for the 4.3 GM engine. Check with Rex Marine (http://www.rexmar.com), they've sold them in the past. I'm running a pair Kodiaks on my 302 F-word powered 16 and they seem to work well.
