exhaust through bumper

[Boots]

Has any one on here put there exhaust through their bumper? It so, how did you isolate it from the bumper? I'm putting on a new bumper i got at pick n pull and want to put it through the bumper so it won't get smashed or beat up. I'm just not sure how to isolate it from the bumper without cutting a huge hole around it.

 

Pic of bumper mocked up, not actually attached yet.

 

it's 4"x6"x3/16" with 1/2" angle in the middle

p.s. Sorry about the cellphone pics.... my good camera broke. Not sure why they are so big but I don't know how to shrink them....

Cut a bigger hole for it to go through, or get a high temp rubber donut to put around the pipe so it doesn't rattle

 

I was picturing something like part number 87235K771 from Mcmaster Carr

Or, weld a pipe solid to the bumper, and then use a short piece of flex pipe to connect the exhaust to it, that would allow the exhaust system to move.

I was originally thinking of something like the rubber donut but figured it wouldn't allow enough movement. I'm going to look into the flex connector thing. Thanks

I would think that if it were welded solid to the bumper you would still end up with a lot of resonance in the cab. Possibly consider combining the flex pipe with some sort of rubber gasket around the tailpipe.
