any 1 had a power flow exhaust, r they any good thinkin about going to calder racing development to have 1 done .
give me some info on this plz.

 

Calder did a powerflow on my 406 V6 and its fine. I don't think there is any power gain but I never expected one given that its an n/a car and no cats were being removed. It looks neat and gives a nice subtle burble on idle.

For a scooby though you could have it as loud or quiet as you want. Personally though I'd be tempted to pick up a decat centre and decat downpipe from the 'for sale' section and then all you have to worry about it a back box. This is where powerflow could maybe do you something a little bit different or you could go for a scoobysport or hyper or something like that

 

C&C Custom Stainless in Hillington. Do a search on here - no where else to go for a good priced, much higher quality than Powerflow and others system

I had a Powerflow twin exit on my Mondeo. Nice exhaust, nice sound depending what your after. In my experience people go powerflow when getting an s/steel exhaust is not easy for a 'not as popular' car i.e. you'll get exhaust for all sorts if they are fiesta, escorts etc. But since the impreza has well established aftermarket exhaust bits, I'd get something that you know of - either new or second hand - plenty available.
