You can remove the one peice exhaust by just taking rear bumper off, jacking up the car and removing the dampers, i've done it before.
Thanks guys. Just spoke to K-tech as well and yeah you're right, cut the old one to remove and the new one comes in two pieces to slip over the axle. Gonna be ordering my Janspeed 182 Supersport shortly! Any thoughts on this system?
What's the benefit of stainless steel btw? And what material is the standard Renault one?
