Recently I have been researching new exhaust ideas thru the forums and thought I would share my findings. You will see I am not an expert by any means but I guess that does not make it less valid...:)

I have a 93 T16 and the exhaust manifold is cracked. So I figured I would get a sports exhaust and filter fitted at the same time as that is changed. Added performance without extra noise were main criteria, also I wanted to be able to buy cheap online and then have the garage fit along with the manifold.
Also, I wanted a original-looking tailpipe - so either nice oval or twin carlsson look.

So which exhaust? Loads of advice online, here is what I found;


1. JT 3"

The ultimate performance option seems to be 3" JT stainless + 3" downpipe, but needs battery moving and thought noisy.
I don't want more noise, or to move the battery yet, so will go for a 2.5 alternative instead and hopefully get it plumbed to 3" downpipe some day.

2. Ferrita
Ferrita offer a sports system with cool twin tailpipes but only for a 900i as far as I could find.

3. Abbot
They have a v expensive model, which their site says they have sold a large number of over the years (so must be good, right?). Now they are offering an alternative £399 stainless jobbie, to be more competitive on price. I am wondering that lower price = lower quality and as they are performance oriented might be noisy. And no
easy tailpipe options.


4. Jetex
Offered by a few places, there is a non-cat full version (61-K) maybe suitable and also a cat half version (61-H2). Jetex are not sure themselves if the 61-K can be used because the 'saab downpipe might have changed'. Anyone know?

The non-cat version seems preferable if possible, because you get the whole thing for not much more money, allows easy replacement of cat, and has cool twin tailpipes. Just shame its not stainless.

5. Powerflow
Generally slated on saab and other forums, but this seems to related more to the quality of the guy building it than the components. I liked the idea of going to our
local place for one of these but agreed with the comment - how can a lego-type of exhaust assembled ad-hoc compete with one performance designed? Another was that these are focussed on look and sound rather than performance. I am not after a turbo-nutter drainpipe so left it there.

6. Janspeed
Don't offer a model for a classic as far as I can see.

My conclusion

So this is where I got to so far, Any comments welcome. Prob I will go for the Jetex, as that is a nice simple web purchase and hopefully can fit the non-cat version.
But would have preferred a stainless option.

The JT gets my vote because of the price and performance and sound, its not loud at idle and under normal driving, its only loud when you boost and its a nice sound.

What year cars got the square ended exhaust pipes? (my old 900 has had one retro fitted). They look good (and are original saab spec too)

I think you might struggle to get a sportier exhaust without getting any extra exhaust noise. That seems to be a side-effect of the 'sports' bit.

A bit of extra noise is nice! :cool: I don't know why you wouldnt want it! ;) I'm not talking boy racer fart can noise!, but a real car should have a nice burble and a bit more of a roar when you open it up!

Well, I am interested in ShadowWorks comments, if the JT is not any noisier at motorway speeds than the standard then it might be a goer. I want to keep the car looking original and sounding subtle.
As the man said, less is more :)

I got my 2.5" catback made for $129 including a chrome tip. I'll post pics once I get my Airflow kit installed :D

Have you considered Longlife?

http://www.exhausts.uk.com/home/?a=1

I had a quote for my 86 T16 of £299, that comes with a standard 2.5 round end and you can choose anything else from their selection if you are prepared to pay a bit more. I am just waiting (still:x ) for my exhaust to fall apart. I then plan to get the JT downpipe (battery has been in the boot for over a year) and get Longlife to do the rest. General opinion of their work is good, several people here have them - try searching (I have one on my Honda Civic also) and they will tweak the silencer to give as much or little noise as you require.

Just thought I'd try and add a little more confusion;)

Thanks Nick. I had considered Longlife briefly, but really preferred the idea of getting something mail order.

Bristol is a couple of hours away, but I could combine a saturday visit there with a sunday Cardiff trip I am doing soon...:) Thanks, I'll ask them for a quote. The option to have the noise level tuned is a real benefit.

I just replaced mine with the oem, and I love the oem burble.....
If anything I'll add a sport cat and JT downpipe later, I dont think I'll ever go over 250 hp anyhoo......

I guess there is also a valid argument for just getting the cat section replaced, for now, then upgrading the whole exhaust later on with the downpipe too. From the info around seems the cat removal improves performance and mpg.

There must be several 'exhaust' specialists within reasonable radius .. Hunt one up and have a 'Bespoke' system made usually much better quality/fit for similar or often much less cost than some Store's heavily Marked up (Price) affair.

I did my full system replacement on the vert. using cheap parts and it seemed fine for the 2000 or so miles that I owned the car for. Moving the battery is the main obstacle to replacement of the downpipe.

The main benefit of the 3" downpipe is that the cast elbow is eliminated from the equation. The cast elbow forces the exhaust through a 90 degree turn at the point when the gasses are travelling fastest (post turbo) If you smooth out that sharp bend your making a big improvment.

What I'd recommend is that you aim to remove that elbow from the top of the exhaust system and keep everything from the downpipe back as standard OEM specification. An ex. c900 performance tuning nut (Pete Tandino - you will find his old posts in the forum) achieved 260bhp with this exhaust setup, although he did remove the center silencer - but for noise concerns I would be tempted to keep that.

The 3" JT downpipe keeps a restriction in the neck where it attaches to the turbo. It is much better than the standard setup but there is still room for improvment. The good thing about the JT is that it's reatively cheap.

Another way to approach the situation would be to get something like PDA's setup. He has had his downpipe built out of 3" section cut and welded into the right shape. This is probably about as good as it gets - http://www.saabcentral.com/forums/showthread.php?t=52587

Thats a very interesting idea, putting the funds towards a battery move, 3" downpipe & losing the cat instead.

Later on, usefully, I could get a Ferrita standard stainless exhaust for the rest, which is off-the-shelf and even has the nice tailpipes I want :D

Longlife just quoted me £449 for a system from the cat back, BTW, even though I specifically asked for a quote for the whole thing ex-cat :confused:

Hey pda, nice pipes ;)

Can I ask you about the battery move to the boot.

You fitted your battery on the right side and it came slightly through the floor. How did you decide this was the best place etc? I was thinking, possible to get the battery into the spare-wheel-hole instead, completely hidden? If so would a sideways/different battery type be needed etc. As you have already gone through the thought and application process...

Wide angle downpipe

I've built myself a 2 1/2" stst wide angle downpipe (yesterday), it worked out @ about £70 for 3 bends and the flange to bolt it to the wastegate, i'll get some pic's tonight to post. It was alot cheaper than the 3" version and it's a bit easier to put together as you have that extra 1/2" to fit it around the side of the engine bay. took 10hrs to take off my manifold & turbo, grind out a crack on the manifold, bake it and weld up, then stick another turbo on, bolt it all back to the engine and then get the zorst pipes cut and welded. I was shattered come 8 o'clock last night when i finished. It looks :cheesy: though, nice long sweeping pipe comming off the wastegate, will be a few days to test it though as i've got a few other bits to sort.

my decision was easy I'm too tight to waste £100+ on a dry cell racing battery :cheesy: :cheesy:
plus I wanted to keep my Spare wheel..I have not lost much boot space if any
