The 'look at what I did today' thread

YouTube · Post by **Sailor** » Thu Nov 05, 2015 4:36 pm

Today I spent an hour and a half in the rain clearing out a sewer. Cooking fat and sweetcorn, mostly, is what it looked like.
We're at the end of a run that feeds 8 other houses and there's a turn in our garden ...

And yesterday my nearest Powerflow franchise quoted me £918 for a downpipe-back exhaust system for the Lude. Hmm. It's more than I paid for the car and more than I budgeted for. The question is: how many bodges on bodges can I get away with?

That's ridiculous for an exhaust system.
Just buy one off a breaker on here!

Yep you could get a hell of an exhaust for 900 quid. Even a decent second hand catback and a Hytech rep would be cheaper.

My power flow cat back was £300, admittedly about 8 years ago, still going strong.
I reckon for 900 notes you could probably get one from Solid Fabs

Thanks, chums. Admittedly, the quote I got was for a custom made system built from parts I chose myself from their selection.

I note that the chat is mostly about cat-back. I need to include and start from the parallel pipe in front of the cat.

Down pipe as well, then.
I have 2 used oem ones you could choose from!

I think the down pipe is OK. It's from there back that I'm fiddling with.

But... the pipe in front of the cat is the downpipe?

The system goes:
1. Manifold
2. Downpipe
3. Cat
4. Centre section
etc.

This is a diagram of an SH Exhaust, whatever that is:-

There's a short section of straight bolted to the cat and fixed to the flexi at the other end. I can't remember if it's welded at this point. This straight holds the lamda sensor.

A hole has appeared at about the sensor position, but 90 degrees to it, pointing straight up at the floor. This hole feels as if it was once round but has now been eroded at its edges - almost as if it used to be fitted with a bung of some sort. The quote I got included replacing this length of pipe.

If this pipe is actually part of the flexi, it looks as if the production process adds it as separate piece as part of manufacture.

This picture off Google also shows what I think I've got, or at least nearly:-

There's an odd plate on the top of the straight section, which may be the bit I've lost?

So, what you're suggesting is that the flexi and this bit of pipe are considered to be part of the downpipe. I get it now ...

[PS: I know this the wrong thread, but we started so we may as well etc etc]

Yes. No.7 is all one piece and is the downpipe.
Type SH is the American type S. H22A8 engine, which had a different exhaust to all the other models (lengths of the front sections are different, so individual parts not interchangeable, although you can swap full systems no problem etc.)
