Does anyone know of all the replacement exhaust manifolds available? Also, which have been proven a good product. TIA.

 

there are quite a few threads on the various manifold options

Megan for $200, DC sports, those are the cheapies.

Full Race has a sick stock replacement manifold, so does Shearer. I'd get one of those, they're roughly $800ish, you get what you pay for.

 

Try this...

Don't forget the wide array of ported/coated stock exhaust manifolds.

 

That is the first one on the list I gave him... I would recommend that route as you will not have to worry about it cracking, no need to waste $200 on a tubular manifold, when you could spend that and have the stocker ported and coated... just my $.02

 

I agree. The $200 tubuar manifolds are pretty crappy and if anything you'll see less gains than you will with a ported/coated cast mani. I saw a dyno chart for the DC Sports and not only did it significantly slow the spool time it also LOST power in the upper RPM's vs. a stock manifold.
