GTB standard with exhaust cutout?

[Guest]

Is it true that the Gen 2 GTB comes standard with an exhaust cutout aka header dump? Apparently it's automatic and gets actuated at the higher rpms.

A pic for people that don't know what it is:

sorta, still dumps through muffler at back, high flow stylez

Yeah I have the standard exhaust still on mine.

The controller is located in the boot, that opens the butterfly valve on the secondary.

You can have it open permanently by hooking the cable over the little notch.

It's not that impressive though, only gives you a little more flow. I would rather have proper muffler to get the suby rumble.

when i had the ECU out for my TT to ST conversion on my 2001 BH, i found the wire at the ECU that controls that exhaust actuator, snipped & extended it, ran it to a micro switch on the dash and simply earthed the other side of the switch. This allows me to activate it manually.

I have a siamese DP and the rest is the standard exhaust, with the exhaust actuator open i get a mild suby rumble and when the missus gets in she hates the rumbel so simply turns it off!

Works a treat!

Nope, it's simply a computer controlled dual entry muffler. I like the idea of the dash switch for it though

Have for ever heard of the varex mufflers? dual entry things that you can control yourself. They are illegal in NZ ("easily modified without specialised tools" or something silly), but i reckon if you hooked one up to the factory muffler control you could get around that little clause.

Cant see anything like that in mine.

I had my exhaust replaced but there is no trace of this ever being in there.

[suspect]

Yeah I got this, can anyone confirm this is related to the green plug under dash RHS? As when I plus this in it goes nuts, and makes a weird sound. I think iv'e figured this out..]

I'll find the thread when I get home from work about this I asked ages ago (years)

Its on Manuals only - not auto and maybe not on some models?

Hi,

My 97 bg legacy man tt has a big exhaust on it, but makes hardly any rumble noise, i checked this switch where the jack goes passenger side boot, as per pic, and the cable connected to the little motor (the one that opens and closes the cut out) was missing. is the missing cable related to my lack of rumble? i clearly know nothing qbout soobs.

[smokn4]

gonna go check my BG now

Interestingly enough I just fitted this muffler on my BF GT had no idea what it was off other than a Subaru the flanges are the same the hanger mounts are the same and aside from being about 1 inch too long a perfect replacement (I have no towbar now if I had tried to fit the GTB muffler with towbar still attached it would have been 5 inches to long)

It cost me $70+ at Magoo getting it fitted new gaskets included. Sound wise I wont be failing any WOF's but its a fantastic compromise between performance and sound.

Drive with the bonnet off and watch your engine actuate... much more fun

[Joker]

yea but everyone has one of those, and I did that with the Avenger all last month...

[94 Leone]

Considering Mine's been cut(don't know when must've been a while ago) will it affect performance at all? what are the negatives of this? or is it like that Xforce muffler where it just opens and closes type deal?
