I suggest you refer to post #68 above, about warranties.

As far as the best uel header ....... it's my take that the "you get what you pay for" rule applies to aftermarket headers.

Personally, I don't see anything wrong with the header that came with the car ......

No aftermarket header even catted ones will guarantee tou wont get the P0420 cel code. See the Basic Bolt on mods guide link below

Any aftermarket header can result in difficult warantee claims for engine problems as your removing and replacing vital engine sensors and moving positions of o2 sensors reliative to stock positioning. Manufacturer could claim that this resulted in changed fueling to engine. Also increase in heat in engine bay due lack of heat shields causing deterioration of components or belts or resulting in higher engine or oil temps.

If your rearly conserned about warantee then dont mod stuff.

They cannot just deny claims, but any mods give them an oportunity to deny or partially claims if they can tie in mods to the failure or accelerated wear or deterioration on components associated with mods

Remember you will be arguing with trained engineers technicians and lawyers and a company with lots of money

But when you gut the header and retain the heat shield, there's no way to tell what you've done (other than sound). A tune is not detectable and easily reversed.

A dealer will try to bully and intimidate you into thinking they can pull the rug out from under your warranty and they will threaten you. It's a crock of shit and in the end, the dealership just wants to make you happy and will work with you. Bring brownies (I'm dead serious- my wife brings treats for her dealer and they LOVE her) and a smile. they will look right past the mods you've done.

I had the dreaded timing cover leak and I was nervous they'd give me a hard time because of my mods (and they had to pay for my OFT they broke in a past service so they KNOW it's tuned). But no issues they did the work and it was no prob at all.

If you getting a known issue like timing cover oil leaks or cam plate oil leaks. then yep they will fix that in most cases without question regardless of mods.


if you had an usual or uncommon issue then they might put up more resistance, as you said it often depends on dealer and your relationship with them.


Tunes left in ECU are easily detectable by looking at the CVN or calibration value number. If even one byte is altered the CVN will differ from stock CVN for that calid.


CVN is like a checksum on ECU rom area


CVN is available to dealer using Techstream or Subaru SSM tool.


If you return tune to stock its less detectable by dealer as CVN will match, except if its ecutek tune with embedded licience in stock rom as CVN is altered.


Dealers very rarely look at this stuff only if they are trying to prove something or detect other visible mods.
