I thought I'd start a new topic to keep everything in one place. This evening I made a start on a stubby collector for the c1j manifold, a few tweeks needed but it should just squeeze in before the first primary.

Ive also started measuring up the downpipe and looking into the join to the middle section. Im yet to collect the middle section, but by the looks of it unless the flare on the middle section is ALOT larger than the male flare on the downpipe, then even with a 2.5" dowmpipe, it will have to reduce down to 2". Obviously this is not an issue when using a 2" middle/rear section, but to keep 2.5" throughout a larger male flare will be needed to keep the bore size at 2.5".
This will mean either two different downpipes, with different sized joins or one downpipe and two different sized link pipes to the middle section. I suppose the main thing is, how many people would want a 2.5" full system?
Im collecting a middle/rear section on Sunday, so I can take some more measurements then.
Matt. That looks excellent! I could do with one of them but divided and with a t4 twin scroll flange!
Excellent work looks top drawer.
Looks great the quality of your work looks really good
Keep the pictures flowing :-)
Dem weldz
I can make one up if you need one, just let me know what size pipes and length of collector and whether you want it as a weld on or slip joint type collector.Originally Posted by Matt Cole

Thanks for the comments.this was the smallest I could make with my current torch, so I've ordered a smaller one, to be able to get in and weld it with a smaller outlet opening, which can then be formed to fit a T2 flange.
Are you doing it with flame, MIG or TIG?
All Tig welded, but the first part of the weld needs to be done from the inside.
I now have all the parts to make a downpipe, and the jig is 90% made.
Has anyone got the exhaust bracket, that the downpipe clamps to, at the back of the engine that I could borrow? I just need to set the downpipe end position, then I can get the first one made.
Excellent marry. Looking forward to seeing your progress.
Hi, I've not forgotten about this.I've had so much work on making other exhausts, it's been few and far between to get chance to work on it. I have the jig complete now and I've made a start on the first downpipe, so it shouldn't be much longer before its complete.
Here's a few of the things I've been working on lately.

Matt,
I have someone that wants a 1 piece downpipe ASAP. What you reckon?
Hi Matt, I should have the first one finished by the end of this week. And that's for a T25/28 exhaust housing. I won't get chance to trial fit for another week as it's on my 5 is my daily and I'd need to swap turbos as well. Is someone would be willing to trial fit for me it could save some time?
Let ask Alan.
I've text Alan matey. He's the one that wants one. He said he would trial fit it if you want?
Ok great. Do you know if he needs a lambda boss and the other threaded take off on the elbow?
Matty,
I've ain't him a text. Can you pm me your number and I'll get him to call you.
Pm sent Matt.
Ive managed to get most of the downpipe done to trial fit. Im just waiting for the tapered flange to arrive for the bottom joint. Im going to have the turbo flange made slightly different for the next one, as there isn't much room to do the nuts up, and if there is enough room, I can improve on the flange join.

Looks good. How much are they going to cost.
Wow matt, wow!
Thanks for the comments.
I'm not sure on price yet, I need to get a quote for a different design T25 flange, and work out costings for everything else. This was made from 1.2mm 304 stainless which is a bit more expensive than 1.5mm. I will have a price soon though, and if it all fits up well, and doesn't need any adjustments I can make a start on making the rest of the system in 2.5".
Well it's been a while! This is now the mk3 version. I wasn't happy with the first bend and the slanted pieced section, and I now have a better design that should flow better. I just need to weld up the second section now.
Anyone willing to try this out for me fitment wise?
Here's the mk1 version with the new mk3 version...

That's the lick! Or some other young person's saying
Hey that looks brilliant. If you need someone to trial fit it I will do it.
Ok, thanks Alex. I'll crack on and get it welded up today. Lambda bosses will hopefully be here by the end of the week. If this design all fits in, price will be £240 + Postage.
I also have the jigs made up for the 2.5" system now. So if this downpipe design works, I can make a start on the rest of the system.
Matty, is the latest design 2.5" mate? You note at the top of the thread there maybe different sizes. For sure virtually all people will opt for a 2.5"

for sure alex mikes got a powerflow 2.5 on his and that was not easy coming by so I recon almost all would want a 2.5 system think james5 wanted 1 too
I would but mine would need to be different at front join as I am running an F7pt setup and BBPT downpipe F7pt downpipe so ideally my car would need to go up and have the front part done on site.
As others have said excellent work Matty.Agreed it all needs to be 2.5" system.
Would be great as a full package, exhaust and downpipe combo.
Yeah this is in 2.5". The mains concern is the part that joins the link pipe. If it was to be fitted to a say 2" link pipe, then there wouldn't be alot to seal on the tapered flange join. But as you say, I think everyone would opt for the 2.5" anyway!Matty, is the latest design 2.5" mate? You note at the top of the thread there maybe different sizes. For sure virtually all people will opt for a 2.5"
I haven't decided how many section to make the mid/rear section in. I've heard that the 2.5" systems ate difficult to manoeuvre over the torsion bar, so may benefit from being split into smaller sections?
I think you can buy a colar for things like that, but why anyone would want a nice 2.5" front section mated to a 2" rear is anyones guess!
Theres very few 2.5" rear exit systems out there. GT Tuning used to make one and possibly a few others at most. Most rear exits are about 2-2 1/4". I think my old Scorpion (bought around 2002 so not the old design) was under 2". They can be a real pain getting them over the rear beam without knocking on it or the side of the chassis. I currently have a KTR / Tiger 2.5" side exit.
I know what you're saying. But if someone wants to run a full length system, which aren't currently available, then it could be a likely scenario.
It's all welded up. No lambda boss on this one, but it will give a good idea of fitment, and see if anything needs tweaking.

Looks really good
Cheers Alex. Pm me you address and I'll get it in the post.
Good work!
Where abouts do the larger system knock at the rear? I've heard its where they pass over the rear beam? Is there much room to move the last bend higher to avoid this? I'm starting to make the rear section now in 2.5" and I want to make sure the rear section clears the beam ok, especially for those that run lower then standard.
Downpipe is on its way to Alex now for trial fitment.
Yeah it's the rear beam and as you say, there's less room on lowered cars.
If the run of the exhaust is well designed and the hangers are similarly, then if it is fitted properly there should be no problem (IMO).
Cheers Trev, ok I'll make it so the inside of the bend is at the same point so the additional dia of the pipe is towards the top.
Now that looks special!I know what you're saying. But if someone wants to run a full length system, which aren't currently available, then it could be a likely scenario.

My 2.5" rear exist, (which I never fitted!) has the pipe going into the top of the front end of the back box. Then the internal perforated pipe goes down at an angle and exits, err, I forget, near the bottom maybe. AS I recall it's a somewhat short but large diameter silencer.
So perhaps not ideal for flow, maybe better for reducing noise. But clears a lowered cars rear beam, apparently. I never tired it, but it was on a 'tuner car'; 5 Alive in Lewisham.
What happened the the custom exhaust system's?
Matt sent me a downpipe for trial fitment. I tried it and it was too close to the water pipes so I sent it back and told him what I think he needed to mod, with pictures etc. I've heard nothing since and he's no longer a memberHopefully he'll be back in touch at some point.
Coming soon turboteds full 2 1/2 inch downpipes with afr bungs these are made to fit both t2 and t25/t28 turbos so is one downpipe that fits every turbo
Shame it was sounding promising, I am thinking of going to my local powerflow place and getting them to hack and modify my sidey so exit's out the rear (no extra silencers just use the existing one on the sidey and the rest just 2.5" out the rear)Matt sent me a downpipe for trial fitment.

I can get full 2 1/2" exhaust systems made here easy the problem is posting from Ireland to England, going to try few downpipes first see how it goes and maybe some efi manifolds and f7p/f4r exhaust manifolds as there easy to post. my cousin has a company called just kustoms he builds manifolds and exhaust for motor bikes all over Ireland checkout his Facebook page just kustoms
these need to go in the club shop only, rob can you do 5 to start??
excellent product for the shop we can get 5 and put them in the shop for members only
this is awsum!! get em made. rekon they will fly off the shelf. awsum upgrade
