Hi guys,

No one seems to have done anything like this yet, so I'll put a video of mine up...

Is this something you’ve had made up? Any pictures of the setup?

Nice mate. How did you deal with thr GPF issues? I am guessing this is a GPF back setup?

 

[Australian Barry]

Yeah, I'll get a photo of it when I can. Shame they took it down from the ramps without taking any.

GPFs are still in place.

It's literally just cut just before it splits to the backboxes either side of the car, and then replaced with custom, much smaller boxes and twin exit pipes on each side.

I now get all the pops and feedback that I was very disappointed I was missing beforehand!

I did the same with my car (without GPF) and feels it to be too loud and boomy from the inside now. Dont you have that kind of problem?

 

[Australian Barry]

It does have some boomy qualities, but only really at a certain rev range, otherwise it's pretty good.

I imagine the GPF dampens things down considerably compared to the pre-GPF cars. After all, they just left the resonator out entirely for the new car.

Im planning of doing the sound deadening myself to the back side of the car, as there are only bare metal and plastic everywhere, no wonders its booming inside.

Yeah that's not a bad idea mate, I might have a look myself.
