09 Sierra stock muffler internals

09 LMG Sierra

 

i've been wanting to do a vacuum controlled bypass on something, the Sierra just might get it. would be great to verify the inside layout of the stock muffler, without having to make unnecessary cuts.

 

ANY chance that someone has cut open a stock muffler before? pics?

I'll sell you the factory muffler from my 09 LMG Silverado that's sitting in my basement.

Need to have 5 posts I believe for PM privileges

[aflesch]

So does that mean he won't be able to reply to the PM I sent him?

[Chris]

I think so. So he needs to post about 3 more times

I am going to duplicate my PM just in case you can't see it:

 

I just measured mine and the dimensions match yours. Where do you live? I'm in western Wisconsin (just outside the twin cities). I'm thinking $40 plus actual shipping unless you are close enough to pick it up. I will meet you half way if you are closer than 1 hr.
