Exhaust Header VS Manifold, which is the better choice?

The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.

Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. SPELAB offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed.

Good for the price

I bought these for my 2005 325ci. Fitment was almost 100% correct but the header for cylinders 1-3 was about 1/4 inch short. I would still recommend these headers for anyone on a budget.

Thanks for the review!!!Very much looking forward to your feedback pictures.

Looks and sounds amazing, needs a slight modification

These brought life to the way my car sounds! You will need to modify for fitment, there is no way around it. I had to cut the 02 sensors threads down by a lot on both parts of the headers , they were way to long and wouldn’t fit, tips for installation you will need to remove the shield on the engine bushing arm, I suggest getting a different style gasket and new hardware

Hello. Thank you very much for your comment, I have forwarded it to our product department and we will take your suggestion for testing! We hope to make a better product.

E46 330 catless headers

Everything went pretty smooth most is great. But the longer one of the headers (the front 3) have little to no clearance of the motor mount arm and was very difficult to get in

Thanks for the review!!!

Spelab exhaust headers for 330ci

The product is great, just was a slight bit off on the downpipe connection but nothing major. Easy install aside from that slight fitment issue, would definitely buy again!

Thank you for your comments! Your feedback has been fixed by SPELAB! We hope your next purchase will be a perfect shopping experience.

BMW M54 Header

Good quality welds and almost perfect fitment. My only complaint was I had to modify the location for the downstream 02 sensors as the bungs for them were right in the firewall. Otherwise a well designed product.

Thank you for your review. This is very helpful for optimizing SPELAB products!
