probably dumb, but any try straight thru mufflers from a car?

[pickandpray]

just wondering if anyone has tried the straight thru mufflers on a cb750?

like this: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=360276908895&viewitem=&_trkparms=algo%3DLVI%26its%3DI%26otn%3D2&category=33636

the price is right, just wondering if it would work.  not sure of the dimensions.

I'm running the cyclex 4-2-1 system.

I have not seen those but I know people have used mufflers called cherry bombs.
