https://www.n54tuning.com/vrsf-3-cast-s ... -35is.html

I contacted Mike directly and he sorted out a deal for me. I think the website calculates shipping incorrectly. He also declared the item at wholesale value for customs so the duty was around £20. They come with the fitting kit included and also a replacement engine mount bolt to help with clearance during fitting.

Took less than a week to arrive too. Ordered on the Friday, they arrived the next Wednesday.

Good idea. however the decatted downpipes from VRSF l bought dont look at all like the OEMs, so not sure how the gas flows in comparison - anyone?

Pretty sure the VRSF have a wider diameter, and more optimised flow through the entirety of the pipe.

How did you get the cat material out of your downpipes and was it easy or hard work?
