hey guys i attempted to install my mbrp cool duels turbo back exhaust on my 2003 7.3L and everything went smooth ( the down pipe was HELL lmao) when i got to the muffler were the two tail pipes come together, the two tail pipes dont slide on to the muffler deep enough to clamp on i have tried different ways to fixing it but it just doesnt fit well, i have look to make sure i have everything installed and that they are the right parts but it still doesnt work i would love any feed back or pointers thanks

 

heat up the flare on the muffler...

 

might just be friction holding you up i used machine grafit to get some of my piping together never had a problem with it. its a pain the *** sometimes but good call on the mbrp duals they sound great when they are installed not many guys do duals but they look amazing

 

Its been YEARS (5 or more) since I installed my duals, I had issue with the dual outlet of the muffler as well. I clamped it and it held for a while, then I ended up welding it.

 

Thanks guys for the info, I'm going to keep tinkering with it hopefully get it dobe today and thanks CSIPSD for the pictures they look good

 

The duals on my 99 went together smoothly. I put duals on my 95 last weekend, had the same issues. I sprayed the ends and Y inlets down with penetrating oil and they slid together without an issue.
