I'd agree Ran haha!
But Torque Flow are the only place in the area I've ever used personally and I couldn't fault them to be fair. Exhaust was beautifully made and it was only one bloke renting ramp space within a Mercedes specialists large workshop and he seemed pretty clued up to be fair.
And that was an exhaust for my old Mercedes Sprinter recovery truck of all things. A de-cat and re-map transformed that into something pretty special.
I got them via a Google search and couldn't find a bad word about them, although that was a few years ago now and that was how I read of poor reviews for MIJ.
