Hey guys, I have an almost stock 91 camaro with a 305, and I want to know what size the stock exhaust pipes are? I don't have enough for a cat-back exhaust kit so I'm just going with a muffler, so I want to make sure I get the right one

Thanks

 

2.25"

 

Ok, so the muffler inlet and outlets would have to be 2.5" to fit over the pipes, right?

 

No. Your over-axle-pipe is 2.25" outside diameter. Any performance muffler sold as 2.25" is going to have an inlet size of 2.25" inside diameter. Just cut the stock muff off, slip the loud muff on, and clamp it.

 

Oh ok, thanks man, and I have to cut the old one off?

 

If it's original to the car, then it should be fully welded.

 

Ok thanks, a hack saw should take care of that

 

Yes, but be forewarned, there's not much room for sawing. Most guys use an electric sabre saw.

 

BTW, you can rent those if you don't own one and can't borrow one.

 

I didn't think of that
