WRX cat-back exhaust from Subaru???

[Ric Williams]

I was talking to a local dealership today, and one of the service guys
told me that Subaru now has a cat-back exhaust available. It's supposed
to be competitive with the aftermarket systems and cost about $500
installed. Plus, no warranty hassles! Anyone heard anything about this?

another 50 installed sounds about right.

That's good news! Got any details? Like is it stainless, 2.5" or 3", single
or dual outlet? The guy at the dealership said that they'll be installing
one on a customer's WRX in about a week, so he'll know more then, and I'll
be checking back with him.

Will this have a real performance advantage?

You would have zero warranty hassles with putting an aftermarket
catback. There's a comparison chart out in webland with a list of
catback exhaust. It list $, db"s at idle & at a certain rpm, torque and
hp, material, sizes, etc.

able to prove that a simple exhaust change caused other problems so
your warranty should be ok with other aftermarket systems. What this
buys you is the ability to buy and get it all installed while you get
your oil changed I guess. The price is competitive with other
aftermarket systems.

From what i've been told, any performance gain would be temporary. Don't know if
this is the case or not, but apparently if the stock ECU detects changes in
engine performance, it changes the mapping to put things back into the
parameters it wants to see, probably undoing any significant gains from a
different exhaust system, etc.
For those more knowledgeable than I, am I on the right track here?

I know about the whole Magnuson-Moss Warranty act and all, but so far the
service manager at the dealership where I bought the car has gotten kinda
pissy when I've asked about after market upgrades. If it's a decent exhaust
system, at a competitive price, *and* bypasses any tantrums (justifiable or
not...) from the service manager, it sounds like a good deal. If it turns out
that they're gonna be pissy about this too, I'll be going to a more
performance oriented Subaru dealer across town, even if it does mean an extra
30 miles per round trip.

Although I have heard of the Subaru ECU sometimes working against you,
I'm not sure that this applies to a catback since all it's really
doing is relieving back-pressure. Now, a new intake or new
intercooler or something along those lines would probably need some
engine mgmt work to extract all the gains since you're introducing
more air into the system which would call for more fuel, etc....

I'd love to hear more opinions on this....

ths stock cat back isn't that bad. it's VERY quiet, and doesn't
create much backpressure. replacing it will give you ~7hp or so. not
a lot, but just enough to feel. when you start uncorking the rest of
the exhaust then of course the bottleneck becomes worse, and the gains
to be had become greater.
