Quietish BB's
#1
I want to change the BB on my MY00 (adding a Dawes MBC and ITG Panel filter too), but not to a loud'un. I've had suggested a Magnex 3 1/2'' as a civilised alternative to the standard BB ... any comment please?

Ping,just fited a Magnex 6+4 oval today.Bought it second hand in the for sale bit for £150.Build quality is excellent and the sound is superb,a lovely deep burble at tick over and a nice roar when you gun it but not to loud so its annoying.Looks great on the car and fits snugly in the cut out in the bumper.Best £150 spent in a long time

Steve,
I was running a decat mild steel DP, standard midsection with cat
removed, and a Remus BB. Actually sounds nice, not so much outspoken 'aftermarket exhaust' note, but more a mix of engine and exhaust, still with the nice boxer warble, though. Easy to live with, reasonably quiet inside car (MY00 5dr) but not at all quiet outside. However on Saturday I exchanged the BB with a friend's Magnex 6x4, and it's far noisier now. More so inside the car than outside. Must say I hadn't really expected that much noise after reading people's posts about e.g. Scoobysport vs Magnex etc etc.
Quite frankly I do actually find the Magnex a bit annoying between 2500 and 3000rpm, sounds like a helicopter (waffwaffwaff... ) That's why the previous owner wanted to get rid of it. BUT the howl on high RPM/WOT is fabulous, and my problem is the missus don't quite agree!! Which means I must now drive EVEN MORE carefully not to **** her off.... Oh, well might get used to it after a while, but now actually thinking of swapping back to Remus.
Will have to check out how it works on longer (+ 200km) trips first.
Simen.

The Magnex sounds a bit too loud for me (and defo my wife like you!), but the Remus sounds promising ... I like to be able to hear music in the car, not just the exhaust note, no matter how beautiful it may be!

I've got the WR prodrive jobbie. I think it sounds the best of all I have heard IMHO but it gets a bit droney on the daily commute. The WOT and fast stuff sound great but this doesn't happen that often....
If only we could have an adjustable one like the legacy system?

PING -
The WR Sport makes a lovely noise - just a bit annoying on the motorway at a steady 80ish. I have a wagon which is worse for soundproofing anyway. I'm hoping a Magnex resonated centre will tame this a bit - it's being fitted tomorrow, will post after.
Must admit I could be persuaded to try Remus if it's a bit quieter. Oh, and I like the look of those twin 90mm pipes
Also, suggest you try ringing a few more dealers, what your dealer said doesn't stack up. What they may be talking about is the backbox from a PPP - this is not available seperately, only the P1 and the oval WR Sport. Were they trying to persuade you to get the PPP per chance - one tried this on with me to!
Cheers

Thanks to all for the input ...
Seems that the Remus is quietist, if not the best sound ... as you say Floyd - great sounds are wonderful when you get the chance to have a blast, but this doesn't happen often enough!
Tim,
I think you're right about the PPP BB ... I think the dealer was either confused or hoping I would spend a lot more money!
Mines a wagon too, so soundproofing is more of an issue.
Gavin,
Thanks for the name ... you feel it's quieter than the original fitted ... that's seriously quiet then!
One advantage of the Remus is it's a lot cheaper - £200 ish as opposed to 350ish for a Prodrive I think.
Having said all of this, I guess it IS worth changing just the BB isn't it?

Theo said he tried a Remus and found it more restrictive than the standard twin pea shooter, but GavinP rates the Remus. The STi one is probably only like the original twin pea shooter with a different tip from what I heard - quite restrictive.
#14
Yep, I've found the Remus as Gavin says - it might be measurably more restructive than the entirely flow-through type, but not worth thinking about. I noticed a marginal - and I mean enough to not care about unless in an obsessive mood - reduction from a Scoobysport to a Remus. Wayyyy better than the standard pea-shooter anyway

Thanks ... beginning to think that I'll wait 'til I can do the whole exhaust as it sounds like I will only gain a great sound and not much flow improvement.

Echo that.
The STi BB flows the same as the original, sound levels the same too. Just a single, larger exit pipe. All it does is look better IMO.

Steve,
I did the Remus backbox before the downpipe and mid section and it flows a lot better than the standard pea shooter !
Before my car wouldn't rev beyond about 6500rpm - after it got to 6800.... (auto box) Not a definitive measurement by any means but does show it is less restrictive
I haven't tried any other backboxes so I don't have anything to compare against (apart from OE) - the downpipe and centre change did make a much larger difference though.
If you want quiet, then it is king but there is probably more performance available if you can take a bit more noise...
Thanks
Gavin

Ping,i did have a standard bb before and i was concerned,as u r,with a after market exhaust being too loud,but in my opinion the magnex is perfect for me and the wife.
Yes it is a bit louder then standard but by no means annoying you just hear the warble more:d plus the build quality is supperb.
Hope u get what u r after soon, Kiaz

Anyone near Hertfordshire with a full de-cat and a Remus backbox, ideally in a classic wagon?
Would be interested to meet up to compare with my Scoobysport/Magnex/WR Sport system.
(Considering swopping the backbox to Remus if much quieter).
Cheers

Kiaz,
Jamie at performance exhausts sent me an MP3 file of the Magnex BB ... does sound smooth I must admit and not outrageous when pushed! I'll find what I want in the end ... hopefully!

I have an oval WR backbox that I'm taking off and changing for a PPP one shortly (cos I want a round one not an oval one......how sad).
I've got a scoobysport dp, magnex centre (with resonator) and the WR bb. I think the noise is just right. I drive a good 70 miles a day commuting and it's all on fast B roads. I don't find the noise at all intrusive. A friend has a scoobysport on a non-decatted car and I find that just too noisy.

So the STi backbox is the same as standard just in stainless steel with a big exit pipe? That is a serious waste of time then. On the STi site they mumble about their exhausts which are free flowing and have a deeper sound(translated from Japanese). Are there 2 types of STi exhausts then???? Both stainless with STi logo and large exit pipe cos I am confused???

The STi BB I'm refering to is the STD one that is OE on the old shape WRX STi's, say a V4 for example. They are not Stainless steel either, the tip might be, but the silencer isn't.
hope that clarifies things

Thanks Jay m A/Justin, I understand now. So most STi backboxes are just the normal one but with a stainless exit pipe. Is the box on the P1 with the STi logo the same? I presume it is.

Not sure, with the P1 prodrove did a introduce a few new bits and bobs, the backbox could have been a special I suppose.
