exhaust question

[duggywuggy08]

Right now I have a 4 inch straight pipe and my buddy gave me a 5 inch section over the axle and I wanna use it. I was looking at the adapters for it. Could someone help me with what I need. I don't understand what the id and of mean

ID refers to inner diameter and OD means outter diameter. You should only need a 5in to 4in reducer and then you may have to trim the 4in section to get the over the axle part to fit right. Hope this helps.

You should be able to get a 4 to a 5 adapter a napa that's where I got one a while back to make it work!!!

Well there are 4 different 5" to 4" reducers.
5" id to 4" id
5" id to 4" od
5" od to 4" od
5" od to 4" id
(id= inside diameter. Od= outside diameter)
First you need to measure your 5" where u will be connecting the reducer. It should be 5" from the outside to outside or inside to inside. If its a id then the 5" side of the reducer needs to be od. If the 5" is a od then your reducer needs to be a id. Once ya find that out ya need to do the same for the 4". If the 4" is id then it needs to be od on the 4" side of reducer. If its od then u need id.

It all depends whether the exhaust is bumped up for another pipe to slide in. Napa should be able to get it but it's prolly something they are gonna have to order. Better chance or stopping at a local big rig shop.
