Carrier mufflers??

Thanks, and that makes sense. Looking inside it appears to be identical baffle tubes going the length of the muffler. I doubt there's more to it than that.

Note the info on "reversible". Then again, I am not sure if I directed the ones I have used (I have done 3 different carriers in the past few years using these mufflers). All are nice and quiet. I did drill a drain hole in the low spot of the mufflers as well as the pipes to allow water condensation to escape.

Right, I'd put one side on A up and the other B up and the damn carrier would pull to the left...

Well, they're in. The hardest part was creating the right diameter inlets/outlets to take the original pipes (sleeve inside or outside...that's was the quandary). I can see where the originals that are slightly offset would have been better but by shortening up the pipes and twisting the muffler bodies the 17864's work fine (twisting moves them away from the centreline of the brackets but there is enough slop to a point). The alternative would be to bend brand new custom pipes but that would be a long, iterative process. I ended up putting the 'B' side down (B for bottom I guess) and wish I'd used the 'A'. Using the B puts the muffler seam face out and visible and the originals have no seam. Not a big deal but the more cosmetically original the better. I painted them black which will probably peel off but for now, they look damned original!
