Has anyone on here had any experience with these exhausts, I am after a replacement st st exhaust that will hopefully sound better than the stock system but do not want a loud system that's going to drive me mad on a long run. I am being offered a system from the cat back only, my car is 16yrs old with 90k on the clock, 1 owner, I am getting a rattle from the exhaust system which sounds like a baffle is loose which is why I have decided to change the system, but I am unsure as to the need of changing the cat or anything in front of that, any thoughts

have you thought about carrying out the UK mod? I love the sound of mine!

Would not go non Oem,not unless your going high end replacement,for noise/drone reasons.<powerflow is not high end>
Suggest find the rattle as prob the Cat, and if so may ruin your sensor if not fixed.
And as above uk mod,if its your silencer gone get a good second hand one with low prices out there.
^^Thats my next upgrade the uk mod,got the 25mm pipe just need to weld it on ect.,
A Mugen is a little expensive for me.<high end>

You can get a well made custom cheaper than many aftermarkets and better, find someone with a reputation

I had one made locally and I'm well chuffed with it

Also check the cat heat shield, the most common cause of rattle.

Cat heat shield or maybe even the cat. Powerflow in general are not amazingly made in my opinion. I've had a few made in the past and they use a standard pipe bender so you'll have inconsistent diameter pipework and they also use a MIG welded rather than a TIG. Now technically there's nothing wrong with MIG but after seeing the quality you can get out there for similar price i would not considered powerflow.
