exhaust question
what would be the best exhaust setup for a 454 330 hp motor ? trs drive .time for new exhaust and manifolds

Fresh or saltwater? Freshwater I would say stock Merc unless you are looking to lose some weight in the stern. Saltwater I would go with Stainless Marine manifolds/risers. Another option is a set of take-off 496 MAG/MAG HO manifolds/risers. I believe pre-2005 are aluminum manifolds. Risers are stainless regardless of year.

Thanks, KEPP |
Best bang for the buck would be the 496 take offs as Knot4me said. You're not gonna see a lot of performance gains anyway with an exhaust mod on a stock 330hp.
Teague has had them advertised in the past a lot for low$$$ |
thanks to all
any one have a set of takeoffs ? what should they cost? |
There is a set just posted in the classifieds. The ones in the classified are priced about double of what they should be IMO. Also, call Teague Custom Marine.

I paid $350/pair for new take offs just a month or so ago. In the process of polishing the risers.

Exhaust
Was wondering about a exhaust upgrade for my engines. I was considering the alm 496 manifolds, would there be any trq. or hp gain over stock iron manifolds? I have 496(stroked 454) dart pro 1 310cc alm.heads edelbrock rpm intake,hyd.roller, 750 marine demons with merc. stock wet exhaust with accesseries it dynoed at 600 trq 500 hp. Should I consider aftermarket , or the 496s and what should I expect to gain? thanks Dan
