Summary: These are different than all other aftermarket cast manifolds in that they are an offset center dump style, rather than dump back into the firewall like all the others. Far nicer for keeping exhaust heat away from the firewall/floor !!! Why don't the other brands (Hooker, ect.) use this configuration ??? My only complaint is the 3" outlet, as most street systems used with manifolds / shorty headers are 2 1/2", which is plenty for the flow/power potential of these parts. Very good product, though.

Yes, I recommend this product.

Summary: Bought these stainless cast manifolds for an LS3 swap into my 1982 Volvo 242. Haven't got to starting it yet - but these are gorgeous. They make the crate F-body manifolds look like miniature versions! And they move the exit more towards the middle of the engine where I have more room for head pipes. Very pleased so far.

Yes, I recommend this product.
