Overall Assessment

Customers overwhelmingly commend the product for its solid, heavy, polished design. The use of thick, stainless cast material and correct 1.75 primaries with 3" collectors make it an optimal choice for LS engines. It's also appreciated for fitting comfortably in tight engine bays and clearing frame rails in 34 Ford Street Rods. The headers are reported to be of flawless quality, proving durable with no warping due to a thick engine mounting flange. Its high-quality polishing sets it apart, making it worth the extra cost. The inclusion of 3" stainless steel collector flanges, stainless bolts, and gaskets add value for users. Customers would not hesitate to recommend it to others, expressing their intention to repurchase, a testament to its superior performance compared to competitive products.

This is a unique product, extremely well made and better than headers! Like a center drop header, but heavy cast stainless. Wish the un finished were smoother, their a little to rough. Manufacturer needs to cleanup mold..but the polished ones are awesome.

Cast headers sound better than thin wall tubes, these are so perfect in design, cast in stainless nice and thick material not to mention the correct 1.75 primary's with perfect 3" collectors are perfect for the LS family of engines.

The polishing job on the manifolds is very good - well worth the extra cost. You need to include in the description that 3" stainless steel collector flanges, stainless bolts and gaskets are all included and add to the value. I would recommend boxing the bolts and flanges separately. There is some chance of the bagged parts scratching the polished manifolds. I found a couple of places with minor damage, that required some sanding and repolishing. I'm setup to do this, so it was no problem, but not all buyers would be. Some better padding for the manifolds would also help minimize the chances of shipping damage.

Is the outlet on on the header in same location that they would be on stock manifolds? I have a 63 impala that I did the LS1 transplant on. I'm using the stock manifold now, but I'm looking to replace them with these if they can just bolt right up with out any exhaust pipe mods.
