Your noise killers are these 2. I realise this may not be the exact layout of your exhaust (I think you may have twin exit) but the principals are the same
If you are just after noise then you start with the axle back section. These are normally baffled. Something free flowing will give you some extra growl. If you still want more then replace the resonator under the fuel tank. I'd leave the rest as is.



Yep bar the twin exit, those resonators are the ones I have. The scorpion system does exactly what you are suggesting ditches the rear muffler and large resonator, while the Tampa Mod ditches small resonator and replaces the large one with a free flowing resonator.

One is a $300 mod and the other a $1000

I suppose the question is based on the 2 youtube clips which sounds better. I marginally prefer the scorpion exhaust sound, but the Tampa mod also sounds little bit better than stock.

The large resonator will be the one the keeps the drone under control.

Highlights how good the Milltek system is that they can drop this component and create something that isn't drony.

Im also wondering if I just fit an electric valve\cutout and open up it up occasionally for when I want some noise ?

Technically not legal.

Magnaflow sounds nice

Agree, caters for the deeper sporty end of the sound spectrum...sounds nice, but it runs the whole rpm range, in that regards I think the factory system is great in that it covers a full range from deep sporty burbling sound under load in mid range rpm and that roaring\screaming\raspy sound at high rpm....just needs a little more noise at low rpm and a bit of a sound increase across the board to make it heard a little more.

Hope you get the sound you are after
My Legacy sounded like this. Quiet when cruising but let you know that there was something going on when you gave it some stick.

Love the 3.0R, almost got one before discovering the joys of German cars, otherwise would be in a modded 3.0R now. Planned to do headers, exhaust, intake and remap...apprently good for around 210KW of NA goodness (gain of 30kw over stock, and same as a stock 2L turbo manual)

Yea, mine was around 210kw. 165awkw on the dyno. Linear power delivery and a torque curve so flat you could eat off it. Best engine I have had to date. The problem I had with the Legacy is that it's an "almost" car and needs a lot of tweaking to make it a really good car. I could just see myself pouring more and more money into it.
ECU remap alone sorts out pretty 90% of all the engine issues if it's done right. The tuner I was using even worked with me to to get the exhaust note right.
But it needs more supportive seats, better sway bars, more feeling in the steering and so on and so forth.

So now I have a MK5 GTI. ECU Stage 1. Job done. Everything else in the VW is pretty much spot on.

We used to have a 04 (BL5 series) Legacy, used Gary Capper in Pukekohe for tune (subtech front pipe, simota filter and nolathane LCAs) that was running 190KW at all 4, really liked that car just not enough space for 2 kids and all the paraphenalia.

Currently sporting a Infiniti branded Fuga 450GT...(250kw RWD) but next family sedan will be a Euro (eyeing up an S5 Sportback or tuned A7) as you say they just work well out of the box with minimal effort and feel better built compared to most Jap cars.

After watching this video many many times im starting to think the tampa mod might be a little too "Wookie" sounding ? not easily reversible either compared to a cat back.

Contacted demon tweeks today and asked about Scorpion and Cobra system....listened to quite a few Cobra vids and am really leaning this way, but various accounts say it might be quite loud.

If it helps, here are pics from an A3 3.2 rear muffler and a MK5 R32 Rear muffler:

A3:


R32:



Both have been hacked up, but you can see the design/flow. Both had glasswool packing in the left side chambers. The R32 internal pipes were joined up in basically the layout you see - I was altering it, but have gone a different way, for now.

Just chop out the rear muffler as a test and see what it sounds like. Maybe all you need is a Y pipe

That does actually sound quite good, id be worried about drone at cruising speed though. After watching a few more Cobra vids the non resonated will definitely be way to loud. I picked up a Demon Tweeks 10% off voucher and added to the discount they already do on a Resonated Cobra it comes to $900NZ shipped...which gives me option to remove resonator if I want louder.

$900 seems pretty good as it will be single cut and weld and if i dont like it should be able to swap back and no doubt another 3.2 owner will snap up.

Don't forget that you will pay another 15% when it arrives here. Anything over $400 attracts GST
