Downpipe Reducer

Does anyone know the exact size I need?

My friend and I are fabbing a midpipe for a Downpipe that I have and I want to make sure the reducer we put on fits the OEM catback.

I'm aware of the ones on ECS and the APR one, I was looking at a stainless one on ebay. Don't want to buy APR, and the ECS one is more expensive than I expected with the shipping.


Is the inner diameter on the OEM catback 2.5"? 2.37"? I know the tubing is typically 16 gauge.

I think OEM is 2.37" I have the APR downpipe, and bought the 3" to 2.5" reducer... it's too large on the OEM size. I guess I'll have to pay for APR one for perfect fit...

I bought it at O'reilly but then I dont rember if mine was 2.5" ID or OD though.
Still I think 2.5" is too big for stock size... BTW you mention that ECS sells the reducer, but I can't find it... any link?

I have a 3" OD we plan to weld to the pipe, and then a 2.5" ID which is what they sell on ECS so I figure it's right

Give it a try first, I haven't try the 2.5" ID yet, so it might fit. But you will need t o use a clamp instead of the OEM band clamp since OEM is 2.37"

yea I just chat with the ECS guy online. He said this might fit fine. I will buy it later to see if its all good or not. But the only thing stopping me from buying is the crazy high ECS shipping rate... $12.xx to ship to my house... total is $25.xx
