Post Borla headers instal, Questions

I just got the borla gen III headers today.

I am just checking to see if there are any gaskets that are needed or does everything just bolt right on to the engine with out the use of gaskets?

IIRC, you're supposed to use the stock gaskets. Haven't done a set myself tho.

Spend $20 at your local Subaru dealer and buy some new gaskets because the old ones will not seal very well and then the exhaust will sound like crap.

Yeah go get some new gaskets for the headers. Remember when Mark and i installed our at the garage day? Well we put new ones next to the block and i resused my cat-header gasket only to listen to it leak. It was a bitch to replace it after the fact. Oh and check the bolts after a day or two. I lost two of the nuts off the headers driving from the garage day back to NY.

thanks for the advice there, I've got the headers coming in a few days. I'll swing by the local garage and get some gaskets for the exhaust. SPO said the headers are in stock but he cat backs are backordered. think it's safe to put the headers on first, then cat back later, or should I just wait and do it all at once.

just curious

The headers went on fine.

just the rusted pissed off bolts on the existing stuff we're a challenge.

I did as you said and got new gaskets.

the gaskets off the block were actually verging on useable.. but the gasket off the cat was shot.

the idle is a little rough and uneven sounding.. I guess "putt putt" is how you could describe it.
overall it didn't get louder, just a ton deeper sounding.

there is a noticable benifit at mid-top end. I've zero'd out the S-afc and I'm going to start re-tuning that with the new setup.

all and all.. I like it.
waiting to get pulled over now for the exhaust.

Fishguy i was wondering how long do you wait after the ECU reset till you start retuning your S-AFC?

I reset it.. then zero'd it.. drove for a little..

then started monkeying with it again, not an overly scientific process.. it never is with me.
