I believe these are CMI Big Tubes but I cannot find any markings on them. They are either CMI or Stelling Green label... maybe one of you guys can tell?? I looked them over with a fine tooth comb and cannot find any markings on them anywhere.

They came off of twin 1000hp blower motors. Low time but they are used. Pressure tested and ready to go!!!

I measured 4"OD on the very end of the exhaust. I also measured 2" for the individual header pipes. I measured from the flange plate looking into the tube. They fit tight up top next to the blowers... not really wide at the top like most which saves space... Great for just about any application.

These pipes are BAD ASS...

$3,500 per set and 2 sets available.

Thanks guys and please let me know if you have any questions.

Is the 2 inch measurement the outside of the outer tubes or the inside of the inner tubes??
If it is the OD of the outer tubes then I believe they are standard size not big tube.

I measured the inside of the inner tube... I'll try to update with pictures including a ruler or tape measure.

measurements added...

They are NOT Stellings for sure....

How can you tell? Just curious. I was told by someone else that they are CMI exhausts... just wanted to verify and figure out how to tell the difference for future reference.

Thanks for the help guys.
