You get a lifetime guarantee with them, which is good. You might need it too as the stuff they weld the exhausts together with has a tendency to rot after a while (as its not stainless). Unless different outlets use different welding materials. Ours up here has a bad rep for that. Can do some good work though for one-off stuff.

They're a franchise. Some people rate them some don't it really depends on which one you are going to and what grade of steel they use. The majority use a low grade stainless steel which is thin and doesnt meet british standards for Stainless Steel - not good!

Some pics to put you off here

Do a search on here as there's loads of posts about them

Had mine for 2 years, never had any problems, no signs of rust, apart from the odd bit of surface corrosion (which you'll get on any stainless steel with salt) over winter with all the salt. Bit of polish always shifts it though .

The grade of stainless steel Powerflow supply them to use isn't even stainless steel really. It's cheap crap from South Africa, just like thier baffles and back boxes. If you are paying that sort of money for a custom made stainless steel exhaust it should last until the car dies, thats the point. But then again, Powerflow are cheap and you get what you pay for.

find a Cobra exhausts dealer. much better quality stuff than powerflow. generally powerflow use 409 stainless. ALL cobra exhaust dealers use 304 stainless.

I visited a lot of franchises and manufacturers during my research for the new business (we are doing custom exhausts) and cobra are miles ahead of powerflow.

NO powerflow materials meet british standards for stainless steel and 95% of them are mig welded. Tig welding is far superior for quality of finish.

You can do it, but you use different techniques to do it. Much better off TIGing it.

some of there outlets are crap and some are good. i just look at it that they have a lifetime warrenty so if it goes wrong then u take it back and get a brand new system for free!

my mate runs our local dealer and he doesnt have any problems with the systems that he makes, well hanst sofar but we did have a dealer in needem market who used to mix mild steel wit stainless.

this is the system which my mate made up for my missus car







and here is my backbox which i made myself at powerflow lol (was cheeper that way but still covered under the warrenty :lol
