He's in California. They are not too strict on emissions there!

 

Yeah, im not gonna cut any cats off it. Not for any reason aside from I just don't really want to.

What inlet did you guys who switched out just the mufflers use, center or offset? Im gonna do the same with the flowmaster, just center it in stock location and try to get it tucked up as much as possible.

When I got my super 44 off road I mounted the muffler as high as I could and cut my pipe off at an angle right before the frame to avoid smashing it. It keeps the exhaust moving out and keeps you from pinching it closed which I did to the stock muffler.

 

Free bump ......in hopes that the OP gets the question answered.
Which muffler inlet to use: centered or offset?

 

It's not an issue only a preference. There is a ton of space to work with because the flowmaster is about 1/4 the size of the stock muffler. Mine is offset inlet and centered outlet.

 

You can use either centered or offset. It all depends on the installer and how they bend the pipes. I would go ask the muffler shops what they think.

 

Flowmaster now make's a muffler that is derect bolt in, here is the info--
