It sucks! That should be awesome. 30R's are amazeballs and love E85.

I'm currently uploading two videos of what I've been up to for the last couple of weeks

[Cam.]

For the car to pass engineering, I needed a quiet muffler. (This has been a really slow process, I'm on the back burner. Long story short he is a busy man and I'm a low priority customer)

I love the idea of varex systems. I hate the cost, look and sound of varex systems.
I could have sourced a GX liberty muffler, Adapted it to the 2.5" centre section and been done with it. Boring!

I had a thought. TT vehicles (Gen2/Gen3) have a muffler that has two inlets and a valve that opens at higher revs/speeds to keep the gas flowing. It's controlled by the ecu and usually fails/owners upgrade and throw the muffler away.

Why couldn't I find some kind of actuator/cable to operate a B4 muffler? I could have the best of both worlds.

So...
A B4 muffler was sourced.
Modified to suit the wagon (Length/Tip)
Inlet modified to suit my current 2.5" catback system.
A cheap chinese cable/actuator was sourced
Some vht high temp black paint was sourced
and I had a switch laying around for some reason

All was fitted/modified by me. I'm yet to decided on permanent location for the motor/switch. It's all loose and yet to be tidied up. (I'll post pics of it when I do)




With the valve closed - It's silent at idle/light throttle/freeway speeds. Has a very slight bark when you are up it. (The video makes it seem loud, It's not. Heaps of that is exhaust rushing out of the tri-flow section of the muffler/intake noise)



With the valve open - It's not as loud as my legamax muffler. It's very quiet on light throttle and has a great bark when you are loading the car up higher in the rev range. Not at all obnoxious or droney.




Very happy. I need to tidy up the wiring and may go for a different tip (GD STI)

I'm doing a solid road trip over the next week in the car. Keen for silence (The missus will love it)

Love your work, Cam! Well thought out and well executed. 

 

Sounds glorious too  

[Jberg89]

Hey man,

 

This is awesome...love it. I know morgs put his switch for the cup holder light illumination mod in his centre console...could be an idea. Great work man

[Meadyy8]

Get a jdm folding and heated mirrors switch, wire for opening and closing of exhaust thats what my light bar is wired into! Give us a bell if for some reason you drop into port or wauchope on your way through.

[Cam.]

Switch is getting put inside my ash tray

I'll try and talk the missus into a port detour on the way home from Byron.

Dem pops and crackles....

[zahmad]

So much H6 want!

[Cam.]

It's a beautiful thing.

[duncanm]

pop an extra fog log switch into one of the empty slots to the left of the steering column.

 

OEM and not obvious what its for.

Nice bit of engineering there Cam.

 

I like how you thought your way out of a problem, not buy your way out.

[Cam.]

Little pointless update!

I just got home from my first proper road trip up/down/around the east coast of NSW and back in the 30. 2200ish km's in 3.5 days
The car slept myself and the missus well, The quiet muffler was bliss, I set the coilovers to soft and enjoyed the ride. I averaged 8L/100km's the entire trip and it didn't miss a beat/use a drop of anything. Stoked!!!

I even got to have some fun on the grass (I'll sort out the gopro footage later)









Oh and some bits arrived: A genuine tyre placard from a late model sti (To suit my enkeis/engineering certificate) And a Aeroklas cargo mat. It's super grippy! My dog's wont fall over and my boot gets protected from sand/water/greasy things

[zahmad]

Nice touch on the tyre placard!

[Liberty]

+1. I wouldn't mind getting all of my placards and stickers replaced with new genuine ones. How did you go about finding the part numbers for them?

[Staxta]

Skid vids? I should also grab one of those placards

Worked out that MY11+ WRX/STI's had what I needed, Rang my local Subaru parts interpreter and asked him to nicely find a part number and order it for me.

I can now sleep better at night knowing that the placard is correct

[Liberty]

Ha ha. Nice man he is. Thanks.

 

They also spelled tyre wrong on the placard.

[RX25SE]

8l/100kms is pretty good Cam.

 

Mine gulped it way through nearly 9L/100 on the way to Sydney, and it has one extra gear.

 

Props on the tyre placard. I did the same with my Commo wagon, a placard off an SS.

[zahmad]

What is this talk of a black Forester

[AB501UT!0N]

Nice touch on the tyre placard!

Thanks for posting up the pic as I need this for my car And great job on the exhaust and it sounds great open and closed!
