Lightbulb Another Exhaust Question

I have some questions if anyone can help me. I did a search and did not find any answers to my questions.
Currently I have a WRX muffler mated to a Stromung midpipe on my 1997 L (automatic ). It's very deep sounding when I am coasting to a red light, deep overall. I am interested in either getting another muffler and hooking that up to the midpipe or getting the Borla header.

- Does anyone have any experience with universal mufflers that give the distinctive boxer sound? Are there any? (I don't have the funds to get a rear section)

-If I just got the Borla 2.2L header and stay with the Stromung mid and the WRX muffler, how will that change the sound? Will it get deeper, will it get louder. I like how its quiet, but its too quiet.

Does anyone have any experience with any/both of these questions?

Thanks,
CJ

Don't know about the L but, borlas do increase sound at WOT (definitely deeper and louder). I think you'll be fine with the WRX backbox. If you don't have an intake, get one and it'll give a deeper sound as well.

Lightbulb

I am running on a Magnaflow race muffler that I purchased from Husker Performance exhaust. The tip is a double wall, and the system has a 3 inch input and 4 inch output. A bit large, but when I got it I was considering a turbo setup. I also have the borla header system, and found it made a VERY impressive difference in bringing out that boxer motor sound. I'm about to complete the piping with a 2.5 inch pipe with a high flow cat. I know this is bigger than the recommended 2.25 inch pipe size, but I also am adding an exedy 13lb flywheel, so the pipe diameter should mate up without the bigger than 2.25 low end sacrifice. I highly recommend the magnaflow, as it is quite remeniscent of the scooby sport, and gives off a fearsome growl when mated to the borla headers. You will need to find a competent exhaust shop to hook it up, as its just a universal stainless steel. However, the price is good (130 bucks or so), and its an absolute blast to listen to. Once I have the flywheel on and the new cat and piping on, I will post sound clips.

Exclamation oh ya...

Oh btw, an intake is a MUST, not just for performance but the intake sound is pretty sweet...

I have a WRX muffler on my L with borla headers. The headers definatly helped with making the car more boxer-sound-like, but the WRX muffler just restricts the sound so much
I do concure with the Magnaflow comment, as Ive heard a magnaflow single tip 2.25" muffler on a subaru and it sounds as distinctive as a stromung or any other great sounding subaru muffler, and for sooooo much less too, good stuff.

And ya, if you havent removed your intake silencer already, do so now to get more boxer sound (and some HP)

Cool

I do kinda dig the custom exhaust setup, but I tell ya, that 4 inch tip is pretty freakin' loud. VERY easy setting off car alarms going through parking lots, or starting up. That aside, the sound is great and the muffler looks fan-friggin-tastic. Would have loved one of the dual tip Mag's, but all those are pretty much for hunduhs, as they all have back-baffles to protect the low end. I didn't want the restriction, and I'm quite pleased with the results thus far. I'll feel better once the whole piping is done, since just a muffler really doesn't do diddly except look pretty. Really counting on the piping diameter working out well with the improved spool up from the new 13lb fly wheel.

Thanks for the input guys.

I had a universal muffler installed when I first got the car back in Jan '02. It was a custom 2.25" setup with a carbonfiber muffler. It was loud, setting off alarms and such, but I drove to PA from Baltimore every weekend, so it was a bit too obtrusive (if thats the right spelling) for me. I got the WRX muffler after my uncle purchased his 3" COBB setup, and the Stromung mid shortly after. I want to keep the WRX rear section as a spare.

I've been reading about Magnaflow and I am pretty much content from what everyone said as far as sound. I have never heard one in person personally. I'm interested in getting either M-14827 , or M-14816.

What is the difference in the tip as far as single wall and a double wall?

Would you suggest the header first before the rear section or vice versa?

I have modified my snorkle to where I can still get a good amount of airflow to the stock panel filter. I also had a MAF adapter with a cone filter, but I didn't like the resonance coming from the filter, so I reinstalled the factory box.

The muffler style that we need for our cars has to have the offset inlet in order to fit right on the car, so I dont think either of those will work... Something more like this:

Well, the deal with the double wall tip is purely this: if your tip ISN'T double wall, and it is close to your bumper, it can mess your stuff up pretty good. The double wall wont get hot enough to do damage on the outside. I can grab my tailpipe after hours on the road, no problem. Now if I put my hand in it, well, that would just be very stupid. My muffler is one of magnaflows universal stainless steels w/tip. I think there should still be a link to husker performance exhaust, where I got mine. If not, search for them on yahoo, etc. They have a pretty good selection and prices were pretty good last I checked. Mine is a race muffler, so its straight in, straight out, and there were no fitment problems at the shop. They just cut off the stock muffler and welded my Mag to the hangers left dangling (plus added a support between). Solid as a rock.

I'm pretty much set into getting this one Magnaflow Dual 3.5" tips.

Which one first: Header or Muffler?

Whichever you can get the best deal on really.. neither alone will make you into a supra killer, so go with what is most economical at the time. But if you want that boxer sound right the heck now, get the headers before you mess with the exhaust too much. The headers really do a lot to free up the sound of that flat4, and if you want to really hear it, they will need to be done. Also, the headers are about as easy a mod as you can do, as long as you have something to help loosen the bolts. Helps that everthing is on the bottom of the motor. You will have a blast with both of them, and it wont be until you do both that you will really feel their benefits. That, and an intiake, at least in my experience...

That looks like a nice setup. I went with the Magnaflow14325 (2.25, offset/center, 14" body, 4x9 SS) Quite affordable at $142 CDN (around $90 USD).

Good power gains, nice deep tone. Lots of people at last Sunday's rallycross sat up and noticed, and liked that sweet sound.
