Did I mention retune needed? :help:

I do hope you haven't stuffed anything but I would think your tuner should find any issues whilst tuning it though if any major damage is done! Hope all goes well

(thought id add this back in)

I think the only way to guarentee perfect fitment is a custom jobby so in that vein Jamies building me a 4in exhaust. I've put it off for years & years but with few extra revs it should see on the street I wanted some big mufflers under there to quieten things down. I'm really looking foward to the change & to finally freeing everything up to its full potential as all the power we've made has been made on the 3 1/2, so no doubt there will be power gains to be had as well.

Will post vids & pics when it's finished

I made a video of the difference. I'll post it tomorrow when I'm at work. If anyone is curious about sound etc it will be a good vid to watch. I'm getting it dynoed in January and see the power difference. With standard exhaust and a bigger cat it made 361rwkw I'm hoping to get close to 380rwkw with the new nizpro 4" setup.

Fg Systems are dearer because they have an additional muffler, ute systems are dearer than sedan because we make them in-house

ba-bf sedan fitted: 2295

" " ute fitted: 3295

FG sedan fitted: 2695

" ute fitted: 3695

hopefully that clarifies things up

Hey Possum

What about the exhaust flapper for the FG's, we are still waiting for one for Bels G6ET
