Powerflow, Longlife or Janspeed decat pipe

I got mine from here.

I get various things from them like pads etc. Very good company.

Powerflow do a 3" bore. I am going to have a custom powerflow exhaust made up at some point but isnt a 2.5" bore and above going to be too freeflowing, ie too little backpressure?

Ah must have just been my local one then, I tried to have a center section made up for my ZR and said they could only do it in 2.25". Few years back mind.

I rate Powerflow, had a slight knock underneath, from my cat back derv ss exhaust ?250. On its first yearly check for the lifetime guarantee, the guy stripped it all down and rebuilt it. Pushed the tail pipe out an extra inch as well.

As some one said, only as good as the guy bending and welding.

My Coupe Turbo one started blowing so I popped in to see my local franchise to say about it and they fixed it for me there and then.

Powerflow added ?30 to my bill for adding a decat!
And that was last weekend!

Anyone with and grinder and welder could knock one up in 20 mins. Really dont see how they can charge ?150ish for them!!! I got a custom one made for my 120 from janspeed as I lived 5 mins from their HQ cost hardly anything!
