Hey I have a powerflow cat back system on my saxo VTS . Iam just wondering what yous guys think of the technical stats from the powerflow website for the saxo VTR which i have posted below? Do you think they are right and what do u think the VTS stats will be? better or worse than the VTR?
''Actual performance gains will vary from vehicle to vehicle. Below is an illustrative example of a test carried out on a Citroen Saxo VTR by 'REVS' magazine. You will notice that Powerflow did not need to remove the catalytic converter from the vehicle to produce the joint - highest power increase. The Powerflow system also produced a better torque improvement than its nearest rival. The rest of the figures speak for themselves. ''
''Brand 'Cat' Removed Power Gain+/Loss- Torque Gain+/Loss-
Powerflow NO +4.4bhp +1.4 ft/lb
Ashley YES +4.4bhp +1.2 ft/lb
Magnex NO +3.2bhp -1.4 ft/lb
Scorpion YES +3.2bhp -0.4 ft/lb
Janspeed NO +2.9bhp -0.5 ft/lb
Devil YES +2.9bhp -0.5 ft/lb
Milltec NO +2.7bhp +1.9 ft/lb
Mongoose NO -1.4bhp +0.3 ft/lb
All figures correct at time of going to press ''

think its all bull tbh.
and pooflow are such a big company you can have an exhaust one week made by someone well then another branch one that is held together with chewing gum

do they use a mandrel to bend the pipes?
haven't seen one up close to determine the quality

Not from what I've seen, crush bends,:n:
I wouldn't go anywhere near Powerflow TBH, very poor quality.

Powerflow IMO are good exhaust, had a custom made twin duplex system on my old VTR, and that thing was quick with the exhaust on, plus it sounded really nice, best sounding saxo ive heard before.
There made by longlife aint they, cos that wat it said on my backboxes :y:

The boxes are fine, its the quality of the work thats the problem.
Some places will do a good job, others not so much.
But when I got my 'lude it had a Powerflow and the tubing was crush bends rather than mandrel, so it had a lot of bottle necks.
And the welding was appalling, if you want to go the Powerflow route research the place that you want to use.

that research was funded by powerflow and given to them so rather biased tbh!

Powerflow do not use mandrel bending machines for making their exhausts, even the main branch in Exeter don't use mandrel bends. Trust me I have been there for the Powerflow training.
You see Powerflow is a franchise, the kind of people who take up these franchises are small businesses that quite often do more than just the exhaust side of things. The reason they are not mandrel bent is because the machines are twice, sometimes three times the price of the hydraulic bending machines that they use. This is what causes the slight crushing of the pipes, it is the way the machine bends the pipe.
Admitedly yes this is a pain in the *ss if you were expecting to jack your car up and expect to see a beautifully crafted exhaust sitting there. It depends where you go, there are places that are an absolute shambles at what they do, as someone who used to work for a Powerflow franchise, i am disgusted at some of the jobs that i have seen. The thing is, if you get someone that doesn't know how to use the machine properly, or they have the welder on the wrong setting then you probably will end up with a f*cked up job. But you do get a lifetime warrenty, so depending on the branch, if there is anything you are not happy with they SHOULD fix it for free.
I hope this clears up a few things for anyone that wanted to know

The old Powerflow boxes were made by longlife, they were another "brand" if you will. The reason your box has longlife on it is because for a while they were using boxes that were cheaper to manufacture.
However luckily they now no longer have anything to do with longlife and everything is now 100% Powerflow
Hope this helps

like i said someone obviously didn't know what they were doin. To be a certified Powerflow fitter you are required to be a qualified welder and you have to go on the training course down in Exeter.
However there are many people that are neither of these, these are the people that give the powerflow brand a good name. I consider myself to be an extremely good Powerflow fitter, i have never had any compliants about my work

I also have a cat-back powerflow system couldnt speak about gains, but it sounds the bizzzness !

The quality of Powerflow depends on what branch you're getting it from, the one in Newcastle (Tyre spot on Scottswood road) is shit and they don't know WTF they're doing!
i had a powerflow exhaust and it was wank, totally crap, Supersprint all the way

my powerflow sounds amazing and that is all that matters to me. as any gains from any exhausts are minimal anyway you may aswell just slate all the manufactuers as they all lie in one way or another. and if the quality of the work worries you then maybe you shouldnt be driving a french car!!!!!!! go german if you want quality

owning a french car doesn't mean that you have to put up with poor quality.
Using parts that are better than o/e means that you can build a better / more focused car than Citroen did themselves.
The whole reason to get a bespoke system is to get something that fits better or where off the shelf systems are not available in a particular style. If done well they should be of good quality.. Performance wise they won't match a race system but they should last longer lol

no thats right kam. i wouldnt change my powerflow for anything as it fits perfectly all the welds are neat all the bends are perfect and it sounds great, it just annoys me how everyone slates them all the time because they heard from someone else who's next door neighbour had one and it was shit. powreflow gave me what they said they would which was the sound i was after and a perfectly fitted ss exhaust.

I think the steel Powerflow use is of a low grade. Hence their systems rust to fuck quickly. If you ever look at a quote for an exhaust the biggest cost by far is the labour. Iirc a £200 back box is something like £120-150 labour so it doesnt fill you with confidence about the quality of the product. The price of a BTB went up to around £600+ due to the price in stainless steel rising but I doubt Powerflow didnt have that problem as they dont used it.
As for the 'lifetime' warranty its only for while you own the car afaik. So the next poor sod will have to fork out for a new system.
V40ER-P - I thought Longlife was better than Powerflow? (in the sense of the quality of steel used).
The only reason I would use them or any custom place is if I wanted a different tail pipe but Im very happy with my Magnex.

Yes Powerflow do use a cheaper grade of stainless, however if you look on their website there are 2 grades available. The grade most dealers use is of a cheaper grade, hence why after about a year the system appers to be rusted. However this doesn't mean your system is 'wack', the main thing is the performance and the sound are still there that is what nearly everyone i fit an exhaust for ask me they want.
And yes just because you mates girlfriends brothers car has a Powerflow system and he doesn't like it shouldn't change peoples opinion considerin there are obviously people out there that DO like their system, otherwise Powerflow wouldn't exist. As the old saying goes "Don't knock it till you've tried it!!!!"

Hmm yes, but varying levels of intelligence among the general population combined with someone having enough money buy a chav-tastically loud exhaust could also be the reason why Powerflow still exists. Along with other products such as Special Brew.
There is also a saying: 'Buy cheap, buy twice'.
Oh and btw, my friend at college had a backbox from Powerflow (and it rusted well within a year) so its not a case of hear say with me.
as said previously, from experience that i have had, i dont rate powerflow.
What concerns me alot is peoples different experiences with them, how can peoples views on powerflow vary so much? obviously is something that powerflow need to look at , as to me it seems some of their garages are crap compared to others...

its because its not straight off the shelf so some places will take there time doin it and some will rush to make a quick buck. at the end of the day they all could be really good if the monkeys who fit them cared about what they are doin.

Powerful = rubbish imo. Ive had one on my 205 and it was awful, loss of acceleration, just felt flat. Had my magnex on, much better :y:. My mate with his older polo g40 had the same situation, except with his the exhaust fell of 5mins down the road, and when he drove it back the guys at the garage said it wasnt their problem as he had driven it whilst it was faulty and therefore wasnt under warranty. Can kind of guess where he told them to go.
As said above though, the figures are based on powerflows 'research', wouldnt trust them at all.
