Exhaust Flange attn: Scott

So i bought an SRT8 exhaust off ebay and i wanna copy what Scott did but to my own needs.

They guy is going to ship me both rear sections with resonators and tips, and both rear pipes that go over the axle to the stock mounts. I asked him to cut off the muffler because i dont want/need it to save on shipping costs.

I need to get a few parts and was wondering if anyone can help.

First i need the flange that connects to the down pipe on the 4.7 because i am not cutting it off the old exhaust so i can sell it as a bolt on kit. Where can i get one, dealership cant get them alone.

Next i need 2 of the stock rubber isolators/hangers, i can get them for $18 each at the stealership, thats alot for a chunk of rubber.

Next, (THIS IS WHERE YOU COME IN SCOTT)

Just to prepare before the parts come in,

I need to know the diameter of the stock SRT8 dual pipes coming out of the muffler? OD and ID

Does anyone know the OD and ID of the stock 4.7 pipe after the flange but before the stock muffler?

I am going to put in a long pipe where the muffler is then a Y, bolt it all together, then bring it to my exhaust shop, have it all welded and hang the rear section. I am just trying to do as much as i can in advance to save on install cost. (per the shops suggestion, since its not made by them they are just gonna weld it)

Re: Exhaust Flange attn: Scott

the SRT exhaust is all 3" and I believe the 4.7 is all 2.75"

Re: Exhaust Flange attn: Scott

OK, so once i verify that i will need a 2.75 to 3" no problem. Then 3" the rest of the way.

Any ideas where i can get the rubber isolators cheaper then the dealership and where i can find a new flange? maybe one thats already 3" ?

Re: Exhaust Flange attn: Scott

The SRT has dual flanges not a single and there would not be much left if he cut them off for me.

I am leaving the stock one on the exhaust i have now because its all welded and i want to sell mine as a bolt on kit.


I am just going let the shop supply the Y pipe and the straight pipe instead of trying to clamp it all together myself then take all the clamps off. I am gonna see if he can get a flange this week, so when i have him install everything we dont need to wait on ordering it if he does not have one.

I just need that flange and 2 rubber hangers.

Re: Exhaust Flange attn: Scott

None with WKs. There is a 99 WJ 4.7 down the road at a bone yard i could check out but i dont think its the same. and its sitting on the chassis.

Re: Exhaust Flange attn: Scott

I have a set off an srt muffler. I figured I could sell it to someone that wanted to put straight pipes in. You can have them for the cost of shipping.

I wonder if they are the same size or not. Being that there is 2 on the srt vs 1 on the 4.7. hmm.

Re: Exhaust Flange attn: Scott

No, the new muffler is welded directly to the flange so its bolt on/off.

---------- Post added at 08:45 AM ---------- Previous post was at 08:44 AM ----------

I want to leave my current exhaust whole for resale purposes.
