Manche_Lover_88 Posted October 24, 2011 Share Posted October 24, 2011 my 88 has stock exhaust piping, 2.25" OD and I am buying a flowmaster 50, I know the smallest size flowmaster sells is 2.25 OD, but I know summit sells adapters, I'm on a budget and don't want to change pipe size, and i am not going to weld it. What I am wondering is if anyone here knows if I will need to order the adapters, and if so, what size? :???: Any help is very much appreciated! Thanks guys!

Eagle Posted October 24, 2011 Share Posted October 24, 2011 If they sell a 2.25" and the pipes are 2.25" why do you need an adapter? Link to comment Share on other sites More sharing options...
HOrnbrod Posted October 24, 2011 Share Posted October 24, 2011 Putting it another way, if the Flowmaster has a 2.25 inlet and outlet, your 2.25 pipes fit it w/o adaptation. Link to comment Share on other sites More sharing options...
Pete M Posted October 24, 2011 Share Posted October 24, 2011 I am literally on my way out the door to grab a 2.25" ID adapter from Autozone. It's essentially just a short piece of tube. Be aware though, that they rust out pretty fast. stainless units and stainless clamps should be available on the internet. Link to comment Share on other sites More sharing options...

I thought the same thing until my dad explained to me that if the OD of the muffler is 2.25", and the OD of the pipe is 2.25" they won't fit into each other.

Pete M Posted October 25, 2011 Share Posted October 25, 2011 or you might be able to find a wide muffler clamp. it's a stainless band that does the job of the tube and the 2 regular clamps in a single unit. http://i01.i.aliimg.com/photo/v0/456835 ... clamps.jpg Link to comment Share on other sites More sharing options...
Manche_Lover_88 Posted October 25, 2011 Author Share Posted October 25, 2011 Oh awesome! I wasn't too sure what they looked like, that helps me greatly, do you know what an average price range is? And will it add too much weight and stress the system? Thanks for all the help! :jump: Link to comment Share on other sites More sharing options...
Pete M Posted October 25, 2011 Share Posted October 25, 2011 doesn't weigh any more than the previously mentioned fix. found this one for 8 bucks plus shipping: http://www.ebay.com/itm/Walker-Butt-Joi ... 5ae3231636 Link to comment Share on other sites More sharing options...

I thought the same thing until my dad explained to me that if the OD of the muffler is 2.25", and the OD of the pipe is 2.25" they won't fit into each other. But muffler sizes are not specified by the OD of the muffler tube, they are specified by the OD of the exhaust pipe that fits in it. In other words, a 2-1/4" muffler is made to accept 2-1/4" pipes. It does not mean that the OD of the muffler inlet and outlet are 2-1/4", it means that the ID is 2-1/4". Link to comment Share on other sites More sharing options...
jpnjim Posted October 27, 2011 Share Posted October 27, 2011 Yeah, the muffler *should* be sized to fit the tubing inside the flange. If it's not, an alternative to adapters can be a tailpipe expander, I bought one from Harbor Freight a few weeks ago for ~$8, but haven't had the chance to use it yet. 25 years ago I needed one for an engine swap, and rented a high quality tailpipe expander from a tool rental place, it worked awesome, and I was able to stretch pipe sizes enough to overcome a problem like this without using adapters. Hopefully the cheap HF expander will do the same the next time I need it. Link to comment Share on other sites More sharing options...
Car RamRod Posted October 27, 2011 Share Posted October 27, 2011 Summit should list if the inlet/outlet is ID or OD. Figure out what your pipes are an adapt accordingly. I'm not wild about band clamps in a butt-joint setup; the front-rear stress bothers me..... though I'm sure it's not a problem. However band clamps in a lap-joint are the tits.

Pete M Posted October 27, 2011 Share Posted October 27, 2011 I've been running a stainlesssteel band clamp on a butt joint under my 88 right in front of the muffler (ever since the cheapie autozone pipe rusted apart and dropped my muffler onto the highway back in like '99). has held up to DDing and wheeling just fine. :thumbsup: Link to comment Share on other sites More sharing options...
Jeep Driver Posted October 29, 2011 Share Posted October 29, 2011 I replaced my rattle can of the cat yesterday. The muffler is a new magnaflow stainless and I wanted to retain it but he PO used a standard clamp and compressed the joint and I had a hard time getting the old pipe out. Instead of trying to insert the new pipe into the muffler enough to reuse the clamp I decided to get a couple of the strap clamps. I'm sold! These Easy Seal strap clamps are the s--t!
