wrx sti exhaust differences
 

What are the differences between the STI and WRX exhausts?

gc or gd?

Gc is simply that the sti one has one outlet instead of two.

Not sure about the gd shapes though

GD: WRX two outlets, STi one
Only other difference was in MY01/02 where WRX had an extra cat in the up pipe.

Doesn't the GD STi exhaust also have "STi" stamped into the muffler tip?

indeed it does. if anyone wants mine - $500 :)

I got one too.

$2500.

:D

In all seriousness though - I don't think they're all the same. Someone told me that the 2.5 STi has a slightly larger exhaust?

Fact or fiction though - I'm not sure?

^^^^^^^^^^^typo maybe.......



the wrx exhaust has a huge muffler, like 8-10 inches huge............

as in ability to make power i am not sure of the power difference between WRX and STi..

I have a WRX MY00 exhaust (catback) $75 :D:D:D

haha you can pick sti exhaust up for $499

Nah not this kind - this one is gold plated ;)

Just incase people get worked up.... I was joking :)

STi gear is VERY expensive though - Genome Muffler alone, new is $1200 from Japan parts. The titanium variant of that is $2k+!!!

Just for the muffler!

STi exhausts come with a single tip muffler with STI stamped on the tip and have been stainless steel since the Version 6.

The 2.5 models do have slightly larger diameter piping and use a single tipped muffler in the WRX and STi
