Wtb: CMI Sport tubes for a 502 BBC
I’m looking for a used set of CMI Sport tubes for my 502. They also need to be the swept back and angled down version. Fresh water only please. |
Anyone? |
There was 2 pair new on facebook the other day. Swept back sport tubes for like $3950
|
A little more than I want to spend. |
2 pair in the swap shop.
|
I need them for a 502 not a 525. Thanks for looking out👍 |
E-top and sport tube are two different headers, you can drill the flange to standard bolt pattern
|
I’m aware of the differences of the two types. I appreciate the feed back. So the exhaust ports from the 525 and the 502 are the same and I can just drill the flange to fit the 502 pattern? |

Thanks for the input. Some of the holes do line up though? If so I can just make a template. |
4 do and 4 dont on each side............use a header gasket that fits your head and lay it over the header flange and mark the hole location, its a 3/8 stainless flange and tough to drill but can be done, some of CMI's have both patterns drilled from the factory, GenX
new old stock with cool collar..........https://www.ebay.com/itm/CMI-Marine-...IAAOSw4rVdgrhY |
Thanks |
Is the 496 pattern the same as the 502 as well? |
