This is completely OFF-TOPIC for this group I think you should read the charter!

Can you believe some people :)

Something in my mild steel exhaust rattles. Is this an excuse to get something shiny do you think?

Yes. It's Jap so there will be all manner of options I should imagine.

Great heavens, a Lithuanian harmonium, they are very rare you know.

Can you play onr yet?

Define "play" or ask his neighbours. ;)

Allegedly it's not meant to be any louder when pootling than a stock one. Of course, if I come into my street 'on song' it might be a bit louder hehe.

Is that a mouth organ?

:)

Oooh ready for the Wet Wang Chippie meet.

When the Saab was serviced, they told me the exhaust was corroded. "Oh goodo" I replied, "I like turbodiesels with less restrictive exhausts."

Might be able to get a diesel injector kit for extra soot too...

I just showed my Missus. She said 'is it some sort of vacuum cleaner?'

I take that as a compliment :D

Indeed it will!

You know it makes sense :-p. What kinda power figures does the simple tweakage give with the Saab? K-Tec claim 5-10bhp from said backbox - now usually I think power claims from an exhaust are c*ck, but at least to be fair to this one, the design is significantly different to the standard back box. See here, the standard box is on the floor as well -

I preferred the other one...

Whether it's less restrictive or not depends what's inside the old one, doesn't it? I know in all likelihood it's a bit of pierced pipe with wadding in, but it *might* be a nice free flowing shaped empty space in there...

I know what you mean: the Elise also has a stainless "performance" exhaust. Quiet at low rpm as the original but it sounds like a bomber on full chat. I am not into "noice art" but the Elise at speed resonating through a tunnel is something special.

What I don't like on your (and most aftermarket) exhausts are the endtips. They are seem very bling to me. I always ask myself if they wanted a bigger endtube why not putting a bigger in from the beginning. I have cut the endcaps off : weight consciencous I am. ;-)

Try and find a Hirsch system if you can.

With the variable VP44 unit I have, it's claimed to go from 115 -> 140 bhp,

192 -> 233 lbsft with the unit at 7/10. I have not put the car onto a rolling road, but it sure as hell makes a huge difference with it tweaked up to 7. It's usually set to 1 - 2 to give a little increase in power but no extra soot: at 7 it soots like a good 'un, which I think is great :-) but I suspect Mr. MOT doesn't.

With the tyres I have on there and the unit at >5 it's no quicker until I'm in fourth gear, it just wheelspins the extra power away...

For exhausts, you get the same changes with a diesel as with a turbo. But the bigger the pipe, the slower the gasses coming out, the more noise. I'd not want any change in the diameter; I use the 9-3 on the motorway most of the time and if I wasn't careful it'd grate very easily.

Besides the 9-3 is supposed to be a safe, boring commuter nail... ;)

You should put the Clio on a rolling road now and then after fitted, eh?

I love driving through tunnels in the SD1. Makes me giggle like a little child!

Agreed. Like this :)

Maybe if they do one for the 2.2 TiD, but it will be £££. And I have an excellent PowerFlow dealer not _too_ far from me. Okay so it's like in Hull, but that's hardly far... :)

LOL! Looks like the 2.2.

That's a Mk2 standard box though, same shape as mine but mine is yucky mild steel, and very much on show :)
