So I bought this nice 2" stainless system and it looks really well made and over the weekend did some trial fits so I can make up my own 2" stainless downpipe from the turbo elbow (Metro T3) (as the only ones I can find to buy are mild steel) using a 1 3/4" Metro downpipe as a guide.

Got it all worked out but then I noticed the front end of the new 2" link pipe isn't swaged out to fit over a 2" downpipe. The silencer box front pipe is swaged so fits over the 2" link pipe but the link pipe, being un-swaged, would only fit over a 1 7/8" downpipe. It doesn't even fit the Metro 1 3/4" one, being as loose as.... (avoids smutty inuendo).

So I emailed the suppliers back (with photos) and (eventually) got the reply back that the link pipe is fine as it doesn't need to be swaged out to fit over the Y piece of a 2" LCB.....

Does this mean 2" LCBs are really only 1 7/8" or am I missing something.

Even stranger,

My link pipe is clearly meant to go over the Y piece/downpipe/whatever as it is slotted/slitted for the clamp

It just won't go over a 2" pipe and falls off a 1 3/4" one....
Non-swaged link pipe top, swaged silencer pipe bottom.

Because they only advertised mild steel (as do Avonbar) so I'm half way through making my own stainless one. The real issue is my one is 2" OD. The issue is this 2" link pipe isn't flared to go over a 2" downpipe and that's what I don't understand at the moment *frown**frown**frown*

But if they made one, it would have to be 1 7/8" for this 2" link pipe to fit over !!!!

I'm making mine a real 2", so my question is back to basics, are common 2" LCBs and downpipes not really 2" ???

The supplier says their UN-flared 2" pipe should fit a 2" LCB Y piece.....

these things can vary manufacturer to manufacturer in my experience.

I think most 2" lcbs are 2" od and assume that you will be sorting out your own system on a racer.

when i did my down pipe i resorted to using 2" pipe and bends and a mild steel joiner slid over both.

exhaust ala me...

Yes, I assumed most 2" LCBs would actually be 2" OD so expected the link pipe to be swaged out to fit over a 2" OD pipe (whether LCB Y piece or turbo downpipe) but this one isn't so I'll have to resort to an external joint sleeve or a home made "swageing tool" utilising a BFH.

Why is nothing simple.....

I *think* my cheap no name LCB was 1-7/8" OD, I remember buying a 2" clamp to go over the swaged end of the link pipe which would make sense.

hi,
I've made my downpipe out of 2" and my Play Mini system is 2" also.
A 4" length of 2 1/8" and the welder sorted this problem *wink*

Yes Sprocket and Bat, I can get around this easily with a bit of oversize tube (or even a bit of rolled stainless plate) and my TIG set, or some sort of clamped adaptor but..... why the hell should I have to ???

If I buy 2", I expect every bit of 2" to fit to the next, with swaged fittings so one 2" bit fits over the next 2" bit....

Rant over, welder out....

Hi,
It's no good mentioning mental health on here! *Rofl!* *Confused*
My Play Mini system looks the same as your system and fitted fine over the end of the 1 7/8" pipe on the end of my LCB.
Cheers,
Gavin :)
