Default WRX exhaust on RS

I've read that you can do it, and its a pretty cheap alternative to a aftermarket set up, but 2 questions:

Apparently you have to turn the flange, is welding required?

Is it worth it? Besides looking and maybe sounding a little nicer, any gains?

yea welding is required. is it worth it....eh...i have to say no. theres little or no gains with it and its...uh..basically stock. but it does look better than the stock rs muffler. sounds a little different and all, but not worth it in the power gain department.

I suggest doing a search on this topic, there's been lots of discussion in the past, on which I based my decision to go with a similar setup.
I have a 2.25" custom ss midpipe (catback) w/ a wrx muffler on my RS, and I love it. I definitely noticed an increase in power at the top end. It makes a really nice low rumbling sound just off idle and as the rpm's fall in between shifts.
One of the muffler hangers requires slight modification to get the muffler to hang level, if I'm remembering correctly. A muffler shop can do that easily.
Thanks,
Syncros

i have almost the same set up, but with an STi muffler i got for $20 the pipes are wider, and the flange is at an angle. what i did was keep the stock flanges on the cat, bothe the cat and the midpipe sections. then i welded a 2.25 piping from the stock flange back to the muffler...i never messed with any hangers BTW.

I had the Stromung Midpipe and WRX muffler setup on my RS. Just got the flange on the muffler cut, rotated, and welded. Definite and noticeable increase in horsepower. It's a lot smoother. I'll sell you mine if you want, only had it on for a couple of weeks. Now I'm getting a Stromung catback.

I had the setup on my 01 RS for about 8 months, not worth it IMHO.
No noticeable power gains, but it does sound a little bit better, not much though.

Go with a full catback, Ive got a Greddy EVO right now and love it.

Good luck!

I have a prodrive backbox on mine with cat back 2.5in piping. I didn't notice gains with it, but I am planning to go turbo soon so thats why I chose it.

IMHO the prodrive WRX backbox sounds the best out of any I have heard.

I got a local shop to make me a custom midpipe. I cost me under $100 to have it all put on.

I did the change in my MY2000RS because of the looks. However, the engine should breath better 'cause you are openning the exhaust a little bit. However, IMHO, in the RS, no exhaust will give you a noticeable power gain unless you change the complete exhaust system, top to bottom. Good luck guys.

I am thinking about doing this on my TS. A quick (stupid) question: sedan and wagon exhausts are identical, correct? Just making sure of the fitment.

Thanks!

Don't be ashamed, L power!!!!

same as the RS, the flange just needs to be rotated (I believe that goes for the catback aswell like you said)

I guess the bigger question is WHY? The exhaust isn't that much more free flowing than the stocker the 02 and up folks have and probably the RS folks won't notice anything wither...... As far as the older cars...maybe it'll help...Just spend the hundred or so bucks and get a magnaflow...sounds good..not too loud..

I just don't see the logic on which the WRX exhaust will help any...now the STi might be a little better..I'm not sure of the diameter but I still doubt much...

The stock exhaust is sooo much heavier than any other aftermarket exhausts out there....I put my stocker on for the weekend and couldn't believe how much heavier it was....

Personal opinion here...but save your cash and find an aftermarket exhaust to get the better gains or even sound...

I want the looks and better sound. I have heard conflicting things about the sound, it is louder, it isn't?

I don't expect scoobysport sound out of it, but more rumble would be great.

Maybe I should just drill a hole in my TS exhaust until I can afford an STi, Prodrive, or sonething else

I have a custom midpipe 2.25" unresonated welded to a 02 WRX muffler. From stock. The exhaust note did drop in tone at idle and screams a little louder at WOT. All in all it sounds stock, just a little more grumble. With a Ganzflow (I have) or Cobb like CAI, this exhaust sounds great and will save money for better heads or cams (maybe even turbo).

Default exhaust swapping

I was thinking about doing this too. right now I have an n1 catback and its a little too loud for me. I actually wanted to know if I coudl jsut take off the n1 can and replace it with a wrx can. I want something cheap and not loud. My n1 is too loud. I also scraped it near the midpipe and put a whole in it, about the size of a penny....

so either way i gotta drop about 30-50 bucks to get the hole welded shut or pickup a wrx catback...

anyone know if the piping on a gc n1 catback is the same diameter as the wrx catback?
