This differs depending on what seller the exhaust is bought through. It's a crapshoot in that regard. Mine fit on just fine. There's no interference and the header traces a nice clean line around the filter. There's about 1/8" of the filter that hangs inside the curve of the header and there's clearance on all sides.

Yes, that's the one I deleted. I'm running a flat flange with a thick gasket there where mine connects to the catback.

Gotcha, sorry I missed your comment. Must have been posted while I was answering the other post! Chances are that there is a donut gasket at the back end of your stock cat pipe. When I installed my catback I removed the donut gasket and cut the small stub of pipe off the flange. I then used a flat flange & gasket for attaching my exhaust adapter which steps up to the 3" catback. Just be aware of that incase you want to go back to your stock exhaust.

What are you needing done at the shop? You can remove and install the entire exhaust in your driveway if you've got a pair of jackstands and some tools. That's assuming you don't need anything fabricated.

Chances are you'll get rasp by running catless. You can diminish it somewhat by getting a resonator installed anywhere before the muffler. Traditionally it'd go close to where the cat usually is.

I got a bit of rasp when I dropped my catback entirely. That went away once the 3" was installed.

Check for the EJ stamping on the block... EJ22 has EJ22 stamped on it, EJ25 has EJ25 on it. Then count the cams.

pwned Seems fitting for a sleeper STi swapped wagon!

could be oil pan, sump plug, or a loose oil filter...

Check the fitment of the relay in the socket. Our 2000 OBK had the same issue and it wound up being a bad connection in the relay socket. I spread the pins on the relay and haven't had any issues since.

True, you unfortunately can't use this as a hard and fast measure of if the HG's in the motor are good or not. If the HG's were replaced but the tech didn't clean the overflow bottle then you're still going to see that residue in there. It's a good thing to check but it's easier to determine HG issues by looking at the driver's side of the engine from underneath the car. The HG leak tends to evidence itself by dark marks at the joint of the head to the block. The coolant typically drips onto the exhaust manifold and evaporates while the engine is running which is why you won't typically see puddles of coolant from this type of leak.

Where are you seeing the oil? If it's at the front on or around the timing belt cover then I'd suspect your crank seal. If it's on the heads then I'd suspect your cam seals or HG.

Here's my 2.5 RS with borla replica header, stock cat pipe, and a 3" catback from a GD WRX (BBP brand). The catback is virtually a straight pipe. There's a resonator near the cat flange and then the muffler at the back but they don't do a whole lot.
