Talk us through the quad conversion Machine monkey

Bit more effort and the cutout could look factory :wink:

Sorry been having some down time today!!!

Well I am not sure what more to add really. The cut out is a pain but I am getting better at it. I would rather you arrive at mine with it done.

The quad I do is a tee off system (so you won't get exactly equal flow from each side) but it's not a fake dummy second back box. It's all made from 316 stainless steel. It has the flexible pipe to make fitting easier but also to help isolate the 2 exhaust boxes. I will also mount the second back box on rubber mounts to avoid vibration through the chassis.

PM me Andy if you want anymore info.

Mat did mine. Deeper note (but no drone) and some fun pops and burbles on lift off. Sounds fab.
