Default uel headers on 2.5i

they will fit the ej253 block though they will need to be modified sense the headers go up to the uppipe to the turbo, the subframe is in the way to have the stock pipe modified to connect to the headers, unfortunately the stock headers are made out of cast iron and alot of exhaust shops wont weld that, i would suggest asking some welding shops that are more comfortable with that work, also due to the stock 06+ headers on none turbos having the first cats a part of them you will need to have the afr sensor moved back the block (look up rallisportracing.com directions how to do that) to before the rear cat and get an o2 extension to reach right after the rear cat, there is someone who has done this set up on a legacy 2.5i (same exhaust setup) and did a good right up on it

hope for the best

Not even close. It'll bolt up, but "fit", no. Guys like us are severely limited in our options, but we do have some.

You can use a turbo header, but it'll need work, namely cutting, welding and adding about 2 feet of pipe. There are threads about it.

You can switch over to a pre-2005 style header and cat pipe. it routes the exhaust differently, but it you get the correct parts, will bolt up nicely. Try boxer4racing.com.

There are a few companies that make a direct fit for the 06-07 2.5i, but list them at over $1000. So I'm waiting for this thread to make good on it's promise

Have a Nice Day? no more rallisport...

I just called/got off the phone with rallisport and they no longer make make any N/A El or UEL headers any more for the 2.5i . i am sad to see this but i am not yet giving up hope on finding a uel header and catback system. im going to be looking into TSUDO Headers and TSUDO highflow cat mid pipe to see if that will still work and i would most likely have to rerun my O2 wires and make them longer to reach the other O2 bung holes.
