Maybe old-hat here.
Went to Tomasz Smyk (Rugby-based MR2 enthusiast) who was selling his 2nd hand unit(~2k miles use) that he had manufactured + installed as a trial on his own vehicle. This is his Fb profile btw https://www.facebook.com/niunio1 < if anyone else happens to be interested (really nice personable guy btw)
The looks of this very much lightened backbox(~10kg reduction) with its twin rear exit pipes 1st attracted me (it required a modified crash bar to replace the oem) also with a mesh bumper inset to surround the pipes.
That's the appearance (sadly I cannot fathom how to post a piccy yet :( ) but to these eyes looks good
The added bonus and the main point of this post was a little unexpected from my pov, is that there is a noticeable performance gain throughout the rev range... how much of a gain? maybe 5-10bhp and pulls stronger from any speed (torque) ....dunno! Cost all in £475, this is one very excellent upgrade imo. As a matter of interest he would do a full custom exhaust for circa £1k which of course is pricey, but if it gives anything like the improvement I have experienced with just the backbox it may well be very well worth it.
Sounds interesting but we need pictures!

These are of my car, the exhausts on both sides need some chrome or carbon-fibre tips from two standpoints :- appearance and cabin noise reduction
Looks good!
Sounds very purposeful also:- without the tips it's a tad too noisy in the cabin at the moment, but I have zero doubts when they are installed it will undoubtedly be a tad noisier than stock but not excessively so.
Let's hear it when you have the tips installed.
Always like the way the pipes exit the bumper.
@Gibla I do like the exhaust through the bumper look and sorry, no, I can't see the photos referred to above.

Custom exhaust and though the bumper is the way to go. It makes the car look exotic.
It is probably the best feature of my car but very hard to get right with the alignment and pipe choice.

There was a guy out in California that did several GBs for us long ago. He made two versions, a normal dual version and one though the bumper. Another member made the steel bumper replacement so it would pass through.
I asked him to make me one but he was out of the game so I learned to make my own which was a good move because in order for you to get the tips to align you need to have it welded perfectly while it is positioned on the car otherwise if its slightly cockeyed all bets are off. Im not a welder and this was my first weld job which was easier then I thought with a little practice and some YouTube instruction. If I could do it then anyone can and its fun. I was going for the retro vintage look which seems to get a lot of attention.

You do need enough space. Im sure a solution will come about. I had this idea since 2005 but I waited about 12 years until I found a solution to get it to work for my liking. Its a very difficult mod to get right. If you chose the wrong sized tips or style it can throw off the look for the worst and I have seen some bad examples.

It took me about a year of searching the internet for tips. I had a few examples I would hold up to the car and then return. I then took a chance on some vintage chrome trumpet pipes. The only downside is chrome rusts easily so I have to polish them up but the gleam of chrome is way better than polished aluminum or stainless steel.
For right or wrong
@Dev these are what I settled upon

not on the car yet, still awaiting delivery.
They look fine but just make sure when you get them you are absolutely sure with a test fit otherwise return them.There are many tips to choose from. I had some examples that just were proportionally off when I stepped back and looked at the car from a distance.
I take my hat off to you blokes.
Both for the taste in looks and for the execution.

From the same source as the 'through the rear bumper twin'
(https://i.ibb.co/jwrPGpK/Screenshot-2022-04-26-18-18-50.png) (https://ibb.co/jwrPGpK)
This is a twin loop backbox, apparently de rigueur on Honda Mugen engines + a few other Japanes manufacturers of exotica in the late noughties ie circa 2008 on.
Again, it's meant to be modestly noisy but gives out the same power as a far larger backbox
Supposedly a technical description is given here (from a Mugen forum page)
''Okay, the simple explanation is that exhausts must have certain silencing characteristics in order to be streetable and tolerable to the everyday driver (ie, those that are driving next to you). Most aftermarket companies achieve this by creating a series of chambers inside the muffler that silence the car's exhaust sound. The Mugen exhaust silences by the use of the "twin loop", which effectively cancels the sound waves. This enables the exhaust to be quiet, as well as less restrictive (silencing through the use of the pipe versus chambers in the muffler).
Here is King Motorsports' description:
"Silencing characteristics and the quest for exhaust efficiency: the two requirements imposed on exhaust systems have a contrary relationship, and in practice it is extremely difficult to achieve both. At Mugen, we have continued to employ the straight configuration, with the design philosophy that low exhaust pressure must be provided, and that reducing exhaust resistance is an important part of the ideal exhaust system. The straight configuration is widely used in racing, and is ideal because, as the name suggests, it provides low exhaust resistance. However, large silencers are generally required, as there may be problems with mid to low frequency band silencing and scattering of sound absorbing material such as glass wool with the straight configuration. Incidentally, the inverted multi-layer expansion-type silencer widely used by automobile manufacturers provides stable silencing performance, as the sound passes trough several divided silencer chambers, but involves the disadvantage of some output loss and is larger and heavier than other silencers. As a result of our quest for the ideal design for racing engines, Mugen developed the "twin loop-type silencer," in which the pipe is twisted into two loops and passes straight through the silencer twice. This could be considered the ultimate arrangement, combining the concepts of "absorption" and "intervention" in an ingenious manner. It surpasses normal systems in power and torque over the full range, and provides the required silencing and the clear Mugen-Honda sound."
:) i got to say just from looks alone its exotic and suites the 2s so well 8) 8)
through the rear bumper twin, I saw this in the metal today and it looked really good and when its finished it will look so so good.

Agreed
@Petrus , looks alone wouldn't do it for me :-
this car just did ~2000 miles over the last 7 days, the exhaust has transformed the mid and upper rev range performance (and aural pleasure :-) ) from humdrum stock to a totally different level.
The guy Tomasz works in combo with a team in Poland who thoroughly r+d their exhausts, I am so impressed with just this backbox that if I am able to assemble enough £$ a full custom exhaust will deffo be purchased, ideally a twin-loop with twin pipes 'thro the bumper'

Sadly the 1st set of tips I purchased were the wrong size, the exhaust maker Tomasz is in the process of sourcing genuine BMW tips that would replicate his original concept. The tips should not only make the appearance 'finished' but should reduce the excessive noises from the exhaust(at low revs)in the cabin.

If I did not have the superbike muffler mod, I´d look at the loop. The cat though is also an effective silencer. The difference with the decat is more than 3 dB.

That is a very interesting and efficient way of absorbing sounds using a double pass.
The problem with the stock set up is not enough exhaust length so what they did instead is add choke points on the down pipe and a large heavy muffler. However our cars bottle neck is the downpipe which is an easy 8whp.
Mods, please delete this comment :- it was garbage
Looks like Malian (it means beautiful horse by the way) are making a through bumper exhaust and bumper bar 'replacement'. The bumper bar's only function seems to be as a number plate holder as it comes in two pieces.

Looks good!
Drove the car with the twin-loop exhaust yesterday for the 1st time.......hugely impressed
It's relatively quiet, but provides a great shove at all speeds in any gear.
I was effusive about the twin pipe as in the op. < this one (twin loop) exceeds that in power delivery and is much quieter at the same time.
A single exit(twin-loop) thro the bumper exhaust certainly works, although appearance wise it looks slightly inferior compared to the twin exit...can I live with that? you betcha!!

I really like that. Finally a kit for the masses that gets it right because you need adjustable pipes otherwise it will look off.
My only concern is, its going to be loud based on the size of the muffler.

That's the beauty of the twin loop, it's roughly the same noise level as oem exhaust(with a different note), but have a noticeable performance gain
A few months on .....a different application + set-up
Set Up =
Zero exhaust manifold
Zero sports cat (the mid-pipe)
Tomasz twin-loop backbox
All of the points previously made apply, but ratchetted up to 10
1) Similar to stock noise levels at modest revs/ throttle opening ...maybe a tad noisier, but it's a different note
2) At higher revs the engine note changes from 'flat' as in stock system to something melodic, purposeful,'bassier' < oh and the engine sings up to its redline with ease, totally unlike stock, which in the various '2' I have owned were very reluctant to exceed 6k revs.
Far from a cheap upgrade, but the important thing for me ...I am more than happy at the outcome
Quote from: Gibla on October 27, 2022, 08:41Far from a cheap upgrade, but the important thing for me ...I am more than happy at the outcome
Congrats!!
The free revving is, after the decat manifold, due to the better mid pipe. The sports cat also muffles way less than the OEM one. A pity that most struggle with the emissions test.
But again; congrats!
I particularly like your choice of double loop 8) Third on my whish list!
3rd on your wish list ?

Tomasz twin-loop backbox
All of the points previously made apply, but ratchetted up to 10
1) Similar to stock noise levels at modest revs/ throttle opening ...maybe a tad noisier, but it's a different note
2) At higher revs the engine note changes from 'flat' as in stock system to something melodic, purposeful,'bassier' < oh and the engine sings up to its redline with ease, totally unlike stock, which in the various '2' I have owned were very reluctant to exceed 6k revs.
Far from a cheap upgrade, but the important thing for me ...I am more than happy at the outcome
I am happy for you.
I wish mine was quieter but sometimes quiet means a sacrifice in tone. It looks like you got the best of both.
Last drive today with the twinpipe exhaust(having a twinloop instead), the car had been sold + repurchased. What a glorious sound + a noticeably better shove than stock. A new forum member has bought this exhaust and along with his other mods I'm sure he will regale us in a Reader's ride/New members thread v soon

Yes; removving the mid pipe restriction is surprisingny noticeable and even more so with the restriction of the inlet elbow sorted.
Opening up the inlet has very little effect with the mid pipe restriction in situ.
With the midpipe opened up the inlet becomes the bottle neck.
