I've just put the Aero in to get it's JT full system fitted after initially planning to do it myself.
I'm being charged per hour - so can anyone share what they have been charged for similar?
The work includes taking off the old system inc. downpipe (the nuts have been well plus-gassed so should come off easily) and fitting the new one.

I thought they should be able to do it in 2hrs? (Its an exhaust 'specialist' as opposed to a Saab one)

Cheers - just the info I needed. It should be ready soon so I'll be on the offensive if they start talking 2hrs +
I'm estimating about 15bhp+ for the catless JT full system on stage1 ecu so the test run will interesting...

Did a dynorun before and after fitting a JT turboback. The car was stage 1 as well. Difference was 19bhp, so gaining 15bhp is realistic. I was surprised to see such a big difference, but the dyno operator said the old cat was probably clogged. The stock cat was used for 240K km's.

Howe Eng., did my JT system and it took them more than 2 hours to do the swap, and they are Saab specialists, and having seen them do it, I would be careful that this exhaust place does it right...
A lot of the time was spent in careful tweeking and adjustments to get the system just right in terms of clearance and alignment. Don't forget to check that they put the sport cat in the right way up, (i.e heat shield upwards), and check they haven't bu99ered up your lamda sensor, which is fitted to the downpipe (easily done when removing from old downpipe).
And yes the extra
is very noticeable..


Doh....just noticed you mentioned catless ...ho hum....

Ok its back

Bad news: The boy spent well over 3hrs trying to fit the exhaust with the downpipe to turbo outlet connection being the bad bit. Even with the nuts as tight as possible, there is an air leak. Looking at it I'd say the exhaust is at slightly the wrong angle as the back nut is not as far down the thread as the front one. (i.e. if you moved the whole exhaust slightly up the car it might correct it)
The rest is OK and they admitted defeat on getting it right - They charged me £30 which isnt too bad and I didnt want them messing around any more..
So it's now booked into Carlssons of Leatherhead for a re-jig. Oh for my own garage..

Good News: Its a only little bit louder but not boomy at all and actually makes a really nice noise with things being much more frantic at higher revs - most entertaining and yet to be fully tested. There's definitely an unleashed feeling about it to say the least..
Also - the annoying low end pull 'thrum' when pulling away in 2nd or 3rd too early has all but gone which is great as moving in traffic I often get caught too slow for 2nd and a bit painful to use 1st.
I also need to lift the base boost too, which might improve low end response even more.

My JT exhaust took over 3 hours to fit,but it is fitted perfectly.It was checked for clearance and centralised and stablised well.It also needed to be cut and flared to make the cat and additional pipe required to fit

My JT System took over 3 hrs to fit - Lots of adjustment needed to get it sat just right.

The 3" Pipe is a tight fit through the engine bay and the oil feed pipes for the turbo had to be adjusted to fit round it. It did fit very well though, with no problems sealing anywhere.

Mac-xpert - shame we didn't get to grovel round the floor fitting it ourselves!!!!, would look better in stainless.

The JT is more of a stealthy exhaust compared to the good old [expletive deleted] and popper I have!!

I am thinking an ecu is easier to fit?

Thanks folks - I think I should have asked here before I put it into the local exhaust place - nevermind.
It will be fixed just before my stage 3 chip arrives...should be highly entertaining.

The JT is finally fitted correctly. I sent it down to Carlssons in Leatherhead who sorted it out very well indeed.
Without the cat, the exhaust is a bit louder than standard in normal driving and you can hear it at tickover quite clearly. It's also much louder than standard when you go for it - but sounds very good, with what I would describe as a softish tone.
Still on stage 1 without adjusting the base boost and it goes very fast indeed - in fact above 3.5k rpm it just keeps going and going to the red line with a nice linear push - not sure what the power is but:
1) Custom airbox/open intake/ITG filter
2) Speedparts stage1 (265bhp)
3) No heatplate
4) Full de-cat JT3"

If I'm lucky I might be just shy of 280bhp?
Looking forward to the stage 3 chip arriving, althought I can detect the clutch is starting to slip ever so slightly

PS - very impressed with Carlssons...proper customer service at last!
