Ok so I bought a 2 1/4in Cherrybomb Glasspack to figure out my exhaust is a 2in so would an adapter that's 2 1/8i.d. to 2 1/8o.d. make this muffler work, and no i cant return the muffler its all scratched and it's the red tube (that's what I get for changing it in my driveway.

 

No that adapter WONT work...Most of the Time for a muffler the measurment is the ID so that way it can be a slip fit and clamped.....what year is the jeep?

 

you can actaully get a coupling pipe thats 2"ID to 2,25"ID and it will slide over top of the stock exhaust and the cherry bomb, keeping from making a bottle neck

 

It's an 87 i has a 2in exhaust pipe if im not mistaken and the muffler is 2 1/4

And i figured the 2 1/8id to 2 1/8od would work because it would slip over the exhaust pipe and the muffler would slip over the other end

 

I've never heard of 2 1/8" exhaust adapter and I've been selling exhaust for a very long time. Assuming your exhaust is as you stated 2" you need a 2" ID to a 2.25" OD adapter.

 

i need to be 100% sure of size because i have to drive 25miles to pick this part up how will that adapter work?
autozone sold me a 2 1/4 id to 2in od and i matched perfectly with the size of the muffler and the pipe itself

 

You need to reverse that, exhaust tubing is OD and mufflers / converters, etc.. are ID. So you would need 2" ID to slide over your 2" OD pipe and 2.25" OD to slide in the nipple of your 2.25" ID muffler.

 

Thanks, i will only need 2 clamps to make that work correct?

 

yes nut you should crawl under there and make sure no other clamps are rusted and broke.....

 

Well Its officially on there straight piped into a glasspack for now waiting on a tailpipe. also got my new projector headlights installed will upload some pics asap
