Default wrx muffler on gc8 RS

I know it's been done, and I searched, but I didn't come up with the full details. Anyone know how difficult it is? Are picts available? Comments, or sound clips?
My mrt muffler is ded, so, I thought putting a wrx one would be a cheap, simple option rather than putting on my stock lil tip.

I am just about to do. I can let you know by the weekend.
The WRX axleback pipe flange is not the same as the RS - needs to be rotated. Also I believe one muffler hanger must be cutoff and rewelded to hook up.

I bought a stomung RS to WRX midpipe that solves the flange problem.

I put a wrx axle back on mine today. I think it sounds great. Its quiet of course, but its got more rumble then the stock rs muffler. The only thing I had to do is to cut the flange off, turn it about 15 degrees, and weld it back together. Then it fits perfect. The third hanger at the bend in the pipe is about 3-4 inches from fitting but it doesn't touch anything or is near anything, so I left it there. It felt sturdy with out it.
lemmie know if you have any more questions.

here's the pics. I just ran out and took them, its dark and raining.(sorry)

So if you use the stromung pipe you shouldnt have to weld the wrx exhaust? Where did you find this pipe/how much? My friend is trying to evaluate whether or not welding is a better idea. Thanks for your help.

I bought the pipe used for $75 plus shipping. A new one is $140+ from spdusa.com. The pipe is stainless and 2.25" and removes the resonator. So there will be a noise increase and perhaps a performance benefit plus it won't rust.
The cut and weld and keeping your stock mid will definitely cost less.
I am not expecting much from this mod. A few hp, better sound, nicer looks is all that I am going for. It may benefit a future supercharger or engine swap scenario too.

thanks man...
That looks good. I'm going to have it done at a shop, my cat / mid pipe joint also needs attention. Shouldn't be too much to have done.

Well the WRX muffler and 2.25" pipe are on. The shop installed a new hanger on the pipe as the existing one was a few inches off. The muffler hangers needed some work too. It looks good.

It is definitely a little deeper sounding, but not loud by any means. Sounds good to me. I have not run it on the highway and it was raining yesterday so I didn't have the windows down. My stock intake with the snorkus ectomy is louder than the exhaust at WOT.

Butt dyno indicates more vroom vroom. A worthwhile mod, especially since the shop cut-off the rattley heat sheilds from by headers and cat.

Aside... I had a good chat with the Midas guy. He built up a VW fox with cams, head work and sodium valves. Dynos at 163 hp. I tried to talk him into coming out to the autox. Should be interesting. 2000lbs w. 163 bhp.
