When the idle drops down you can see all 4 pipes snorting when I pop the throttle. The forum brought this to my attention and I had to make a video.

Just food for thought Resonator delete – cutouts to replace the resonators – I think these cutouts are just after the downpipes, around mid-exhaust area. Makes the exhaust sound great.

Here’s a vid off start up
