Question about mufflers

[Magnolia Down]

Hi all,

Is it possible to get a muffler for a BH Legacy GTB that adds more rumble without being overly loud? Any recommendations or is this a waste of time and only done by 17 year olds who hang out at McDonalds with their 'pimp rides'?

Sorry if this has been asked before but I'm new and couldn't find much using Search.

Yes, ask at your local muffler shop and tel them what you're after. I'm sure they'de be keen to help

[mattapo]

yep, put the exhaust flap on a switch

[Guest boostin]

Get a bolt-on Genome. They sound nice.

[Magnolia Down]

Hey, thanks for the quick replies. Is this a case of all muffler shops are pretty much the same or are there any you'd recommend in the Auckland area?

What does putting the exhaust flap on a switch mean and is it WOF-friendly? You can probably tell I'm pretty new at this

[dubbedup]

i'd say they are much of a muchness, altho no doubt a jaffa will pop up and advise of thier fav.

[Magnolia Down]

Well, I'm a Brit which I'm told is even worse than a jaffa so it's all good hehe

the bh has a rear muffler that has a flap that open up when you give it the jandal, its in teh back on the passengers side behind the trim. you can re wire it to be allways open or have a switch on it to make it a bit louder when you want

Cheers man, appreciate the help. This is okay for a WOF, right?

[mattapo]

i think its only turbo

[Guest]

oh, stink! was really looking forward to that!!

[Guest boostin]

And only manual turbo too. No autos got it.

[Pappu1]

so how much of a difference does the flap make? any recordings perchance?

[Guest]

I have a 3inch pipe from last flange to 'SR Racing' muffler with 3inch inlet and 5inch HKS Super Dragger tip... not too loud suprisingly, and nice and deep... cost me $100 off trademe...

[Volcanix]

i find cannon style mufflers to be droney as fluck but a factory "style" muffler with a larger exit hole and tip makes alot of difference with the rumble, i have a fujitsu(imuasjf??) one that came with car and its quite nice rumble without the drone and you dont hear it much inside, only outside : )

I have tried disconnecting the activator with the flap up vs down, and can't hear much difference at idle.

Got all excited about it when first discovered it, but yeah can't hear any difference at idle up vs down. I'm sure it does make it more free flowing though - ECU controls automatically, not sure of RPM numbers/conditions at which it activiates though...

[Jonnysnow]

i wired that little actuator open all the time and it does seem to be very slightly more rumbly when just driving about town however i also decatted it at the same time so its probably more the decatting that the falppy thing.
