Good morning all.
Looking for options for a twin pipe exhaust, keeping the cat. I only want it because it looks better, not infterested in power gains and I'd like it to be quiet, I like quiet!
Any recommendations? Thanks.
Unless you get something custom built it you will struggle to find something twin exit and quiet.

I have a German Fox twin-pipe. It's not loud, but it's louder than stock.
Cobra is not for you, then - it's quite loud. TTE/Remus is a bit better, but I would still put it in the "loud" box.
Zero exhausts twin exit.
I agree with Jason
@Ardent The Zero twin exit is of high quality, v. well made, fits well and imo. a great long-term prospect (if a tad expensive),+looks well on the car.
However, it is louder than OEM. and it does give a performance boost, which the op. stated he wasn't fussed about.

Thanks for that. Don't get me wrong, if a wee bit more power comes with it that's all well and good, it's just not a priority. A little bit louder, again, not too much of an issue as long as it's not raucous!
I will look them up.
If anyone has a video of one that would be even more helpful! (If I'm not pushing my luck! :)) )
I've tried before without much success. More engine than zorst sound recording on a phone. Will be in here somewhere.
Search a combo of me and zero
OK, bit of an update.
I've decided on a Malian twin exit exhaust, (under bumper). Looking at various videos it sounds quite deep and mellow so fingers crossed. It looks well made and very sturdy, especially at it's very reasonable price, but I notice that the mounting plate that attaches to the cat is really thick and there's no captive nuts. I doubt the original bolts with springs will be long enough to penetrate the plate. Also, I'm a bit confused by those spring bolts as, looking at new ones, they seem to have a flange that would sit against the cat mounting plate when bolted up so what are the springs doing?? If the nut is tightening against the flange on the bolt it can't move so why bother? I'm looking to bolt it up with M8 x 50mm stainless bolts and nuts, any problem with that? Cheers.
The springs sit on the flanges on the bolts. The threaded part of the bolt goes through the cat and into the back box. It's a spring loaded joint. You have to bring the cat with the donut gasket into close proximity to the flange on the back box in order to get the threads on the bolt started. I use large G clamps to accomplish this. It's a spring loaded joint. Common on exhaust connections.
Your solution is incorrect and will not give reliable results.
You may need to check with them or wait till it arrives and see.
On the Malian I had, the oem spring bolts were redundant as was the donut gasket. Yes will need a nut n bolt arrangement and possibly a flat gasket.
Be handy if they mentioned this somewhere in the sales blurb.

But that's my point, if the springs sit on that flange, or that flange tightens up against the mount then it can't move. I'm hoping it will all become much clearer when I take it all apart.

When you take it apart you will see. I've been working these cars for around ten years now, so I (usually) know what I'm on about.
I think the thing to remember is Malian do not mimic the oem set up. Hence the thick flange. Theirs is a ridged join between cat n box.
That was at least true on their sport back box set up I had. They may have a different set on their twin set up.
Need to see what turns up in the post. They may have revised their design.

You can't even begin to compare Zero with Malian.
Malian is the AliExpress exhaust of the two.
Personally, for a full system, I don't even find the Zero that expensive.
Oh dear, well we'll have to see. I certainly won't be altering anything on my car to facilitate it. You might see it on e-bay in a couple of weeks! :)) :))

That's usually the (short) lifecycle of the Malian kit.
I've even seen them for sale here in the Netherlands on Facebook. "Purchased from the UK!"
But all jokes aside, it's "fine". The coveted TTE dual exhaust is an absolute abomination on the inside and that was made by Remus. It just looked and sounded pretty.

Not sure if Kevin (zero) does it on purpose. He makes no mention of the fitting kit that comes with his. Which then adds a lot in terms of value for money.
For the twin set up I went for.
3 or 4 new rubber hangers, his own right hand support bracket with extra long bolt to account for the thickness of the bracket, donut gasket, crush rings, springs n bolts. The lot. All in the box. Perhaps his own version of a gaming type Easter egg.
I drove an MR2 with centre exit twin Malian back box
It was loud, constantly loud. All the time.
Thanks for all the comments and advice, much appreciated. If it actually stops raining for long enough I'm going to fit it tomorrow. However, one more question. The mounting plate on the exhaust has a generous chamfer/taper on the inside so designed for the donut gasket I guess. I ordered one from RHD Performance when I got the manifold gasket. The thing is, the one they supplied has an internal diameter of 54mm but other places list one with an internal diameter of 45mm which one is correct? I don't really want to have the whole thing dismantled only to find I've got the wrong gasket!
Cheers.
@Pete McCue Reference your concern over parts required for fitting your new Malian exhaust, I believe
@Ardent trod that path and likely has some advice , beyond that in post #10 above.

Yes, I see he ended up fitting a flat gasket, but mine looks deeply dished as if to take the tapered wire donut.
Can you pop a pic up of said deep dished.
I thought the same, right up until the 2 came together.
There is apic of mine in the link above page 4.
Does yours look like that?

No need, it was exactly as yours, no way the donut was going to fit. It just bolts up flange to flange. I thought I'd strip the back end down so it was ready for tomorrow, but it was all so easy that the exhaust is already fitted and sounds really nice idling and revving but haven't driven yet. Looking forward to getting it all back together tomorrow and taking it for a drive.
Update:
Ok, everything back on the car and taken for a 20 mile road test. Sound wise, it's pretty much perfect. Sounds smooth with no stupid popping & banging on the overrun. Inside the car the sound level is barely any different from stock with no booming or droning, so all good?? Err, no, there is one issue and that is the two tail pipes don't sit the same, which I know is going to drive me insane! I'm going to have to strip it back down again and see if I can manipulate the position of the silencer body to bring the tail pipes more even. :-\

Good luck with that, it's one of the issues with the Malian fitment, the solid flange joint will govern the fit of the back box more than anything else.
You're probably better off trying to bend the tail pipe mounting rods.

Yes, it was a bit of a git, but I've got it quite reasonable now.

I fitted one a while back and found it bang on for the price point. Only had a knackered old stock system to compare it to though.
Funny you should mention the pipes position - had a few goes at getting mine to sit symmetrically, still not 100% but it's stopped bothering me.
Health to enjoy.

I agree, for the money I think it's pretty impressive really.

Boo! I loved the noise I got from a leaky gasket.
