I Have a 00 Cherokee Sport. It just got revived and is in working condition. But its still at the shop. And I was looking at it. And it seems to still have the stock muffler. So im wondering what the pipe size is. So i can order a glasspack for it. Oh also the length of the muffler if you could answer that.

Can I Use flex pipe if i decide to Straight pipe It? Just to make it easier on me. And my wallet

 

Muff & tailpipe is 2.25". Stock muff case is 20" long.

 

So if i decide to just straight pipe it. I Need little bit longer than 20 inches of pipe?

 

Probably so and the pipe may need some bend in it as the stock muff is center in (after the cat) and offset out (into the tail pipe).

 

so would something like an 18" straight pipe and some flex pipe both 2 1/4 work?

 

Just gotta get under there and try it.

 

well My jeep Is Stuck at a shop. I bought a thrush Exhaust. Brand new from autozone for $.99 had gotten a 20 dollar credit. Made me so happy its 25 inchs and its a 2in inlet. so should fit into the piping i hope then get welded to exhaust

 

You are going to have problems if you got 2" I think. The stock muffler is 2.25" ID so it slides over the 2.25" OD cat. Also if it is 25" instead of the 20" you may need to relocate the exhaust hanger that is after the muffler attaching to the tailpipe since you will need to cut some of it away, if you are using the old piping. I am not sure how close that hanger actually is though, so don't take my word for it.

 

The end of the Thrush Is expandable. So if they need to they can Widen the mouth on it. And it's at a Technical Prep School. So it's student's working on it. So Free Labor. I only pay for 1/2 the price of the part. Just the down side of it is. The students work on it. But it is Supervised by a teacher.

 

Is the muff core 2"......as in smaller diameter than the rest of the exhaust????

 

Nooo the inlet and outlet are 2in. The core is 3in. That'd be a dumb move on Thrush to make expandable Inlets/outlets with a 2in core. Lol

 

Then what's the diameter of the case? Getting 2" in/out for 2.25" exhaust is kind of a duh, no? I forgot, u got what u paid for.

 

Im so confused. Im gonna draw a picture

 

 

Share your crayons man! So they don't make a 2.25" and you just have to buy 2" and expand it yourself? I made the decision to replace my exhaust so I upgraded to 2.5" with no regrets.
