454/502 E-Top Headers

"The headers sound great and I have had no issues with reversion. I am very happy with the performance of the CMI headers; throttle response is impressive, especially in the 30 to 60 MPH range. Currently, we are turning 5200 RPM with 28 Bravo I Propellers. Top speed is 82 MPH in my 29' Baja Outlaw with twin Mercury 502/500's. If you are in the market to upgrade, spend the extra money and purchase CMI headers. The sound and performance are outstanding!"
Bert A. / Springfield, MO

The CMI 454/502 E-Top Header Kit is a true plug and play system. There is no need to purchase additional custom tails.

CMI’s 454/502 E-Top Headers are a direct Mercruiser replacement for your 454/502 engine.

CMI headers offer more water jacketed protection than your stock exhaust can provide. CMI uses the same high quality semi-automated process on these headers as with the entire product line. These headers are fully post annealed to reduce stresses built up in the header during the manufacturing process. Best of all, 454/502 E-Top Headers are made to last, they are mandrel bent and formed from high quality 316L grade material. There are no parts to crack, all CMI collectors are forged from American made stainless steel.

This kit is price competitive to other aluminum/stainless manifold systems. The 454/502 E-Top Header is available in CMI’s new low cost satin stainless finish or classic polished stainless finish.
