I am quite fed up with my single pipe Mongoose exhaust, it’s just way too loud and tiring on longer drives. So I’m looking at the OE style exhaust from Magnex, but noticed that Mongoose is now also doing this type of exhaust. What’s the difference between the two? The Mongoose is quite a bit cheaper...

Both made by Collins Performance, who bought the Magnex brand when they went under a few years back.
I have one of the pre-Collins Magnex systems on my 3dr and it fits and sounds brilliant. Had a 2 box Mongoose before and it was awful, especially on long motorway journey, too loud and boomy. Magnex is far more refined.
Having said that, my mate bought a Magnex to replace the original on his Escos last year, and the fit was awful, it went back to Collins in the end and even they couldnt get it to fit right.
Dunno about the Mongoose OE system though, suspect if it's made by the same people it'll likely be fairly similar to the Magnex

Funny as im about to swap my scorpion single centre box system out for a twin box set up. A friend raves about the magnex but again thses are a few years old.

Also i think they sit abit higher as their oval not round, mines standard ride height and still catches from time to time.

So would it be worth sourcing old stock out as opposed to brand new??

You'll be lucky to find anything new, as they've been out of business for a fair few years I think. I bought mine 2nd hand from a guy in South Wales about 7 years ago for Ł140, and i think he'd had it in his garage for at least 5. He'd bought it new a few years earlier and had only had it on the car for a couple of thousand miles before removing it when the car got sold, so I guess that makes mine about 14 years old.

It sits nice in the cutout and the tail pipe is a decent size

There was a full magnex system a few weeks back on ebay....been in storege for 10years i think it said...Ł500

I was watching it.......item 192885208142

My 2wd Saff is quite low and with the standard s/steel centre box on the mongoose big bore exhaust it was a round box which would scrape on speed bumps etc. I have had a custom built oval shaped S/Steel box on mine for a few years now and since fitting it have never had any problems. It sits much higher up to give more ground clearance.

Its not just only Mongoose and Magnex on the market.

Try Supersprint, reputable maker for exhaust systems for high performance cars from Italy. But I think how it sounds is of personal taste, however I personally think it sound way lot deeper and firmer than single box Mongoose. Down side is they do not do two box oem style version.

Hope this information helps.

If you have a 6dg beam means it’s harder to fit the magnex system.

I have the Mongoose OE twin system on my 3-door, sound is more comparable to how it was with the standard exhaust, maybe just slightly richer. I'm really happy with that, but people looking for sound might not be satisfied?
I had no problems with fitting, just mounted it with loose screws first an then started tightening them from turbo backwards and kept an eye on the loose pipes staying in place and not twisting.

Coming back on this after a long while....

A couple of weeks ago I decided to order the Magnex, as to me it had a better name than the Mongoose quality wise. At Europerformance.co.uk it was cheapest at 668,30 pound, so I ordered it there. I expected to get some shipping details in a couple of days, but nothing..... So I sent them an email asking about my order and got a reply that I should have received an email that my order was cancelled because the exhaust was not available and should not have been on their website. Strange that after that email it was still on their website, but now for 751,84 pounds.

Europerformance also have the OE style Mongoose on their website for 612 pounds. Although the Magnex sounded like better quality to me it didn't warrant paying 140 pounds more, so I then decided to order the Mongoose. A day later I received an email that it was not a problem getting the exhaust, but it was too big to ship it to the Netherlands. I need to have it modified anyway to fit my 6 degree rear beam, so I asked if the centre section could be cut and if it then would be OK for shipping. The guy from Europerformance didn't know, so he gave me the contact details of their supplier, which was Mongoose Exhausts. It was quite funny when the phone was picked up someone said "Hello, this is Collins Performance". The reason why that is funny is because Collins Performance is the company making the Magnex exhausts.... So I asked the guy about that and he said that they indeed make both the Magnex and the Mongoose OE style exhaust, and infact the two exhausts are 100% the same. So there was I deciding between the Magnex or the Mongoose....

Anyway, I discussed about cutting the exhaust which could then be shipped without problems. I also asked whether they could change the design in order for it to fit a 6 degree beam. But he said they didn't have the jigs to do that. To me it sounded a bit weird, I had more the feeling he was not willing to go through the trouble. Of course shipping costs (60 pounds) were a bit higher than I initially paid at Europerformance so he said I should deal with Europerformance again for the rest of the costs. So I gave Europerformance another phone call and then found out they had already cancelled my order because it couldn't be shipped.

Seeing that it would be shipped directly from Collins I figured I might as well order it there directly. So Collins gave me a quote for the exhaust including shipping of 944,52 pounds. I then asked him how it could be that at Europerformance it was only 612 pounds. The best price he could do me was 811,84 pounds. Apparently Europerformance didn't update their price in a veeeery long time. But when I looked it up on their website it was now suddenly 852 pounds. Silly that they didn't update the price for the 2wd Cossie, as that is still low.

I then tried another company, but they couldn't ship it to the Netherlands at all, not even after cutting it. In the end I was so fed with all the webshops, the wrongs prices and the problems with shipping. Luckily I found a second hand Magnex at Gary from RS Cosworth Breakers, who had no problems shipping it either.

Lol. Bit of history if your interested.....

Back in the day, we're talking late 80's here, I bought an exhaust from Collins for an Escort S1 Turbo. It had no brand name. This was before Collins manufactured their own exhausts under the Mongoose name. The exhaust was actually made by Tube Torque of Macclesfield; I had to visit them as the exhaust would not fit correctly ! Tube Torque made up a new manifold downpipe for me to ensure a proper fit. All good after that.

Anyways, Collins then moved premises and bought the machines to make their own exhausts. They came up with the brand name Mongoose as their biggest competitor at the time was Scorpion. Mongoose eat Scorpions

Lol at where the name came from.

The Magnex I now have seems to be an older type than the one they sell now. It has one pipe on the left of the gearbox and one on the right. The new Magnex has them both on the left.

bigdel

Sounds like you have the same as me. The pipes run either side of the gearbox then into two boxes then rejoin before the axle. Mines an old pre-Collins item

Hi Marc, can I ask why you prefer the more OE type of exhaust? On my 2wd I have the single big bore S/S pipe with a custom made S/S oval center box and scorpion S/S rear silencer as I found where my car is quite low the standard round shape center one would ground out on speed bumps etc.The place I went to hand make exhaust systems for classic cars and the quality of the oval center box is superb.It has never ground out.

See my original post. Ground clearance has never been much of an issue, as I don’t run the car that low. But the noise is driving me crazy on long runs. I must be getting old....

cossynut2

Fair enough, your single pipe big bore exhaust must have been different to mine as even on long drives I have never found it to noisy inside the car.

Go to Mike Edwards motorsport for a custom 3 inch. Had a few of them done and always spot on and nice and quite.
