Well, it would be rude not to post a video:



Very happy with the decats!

This is LOUD. The go pro was in a full waterproof case (raining when filmed) so doesnt do the volume justice. I live in a village and would feel guilty taking the car out late at night...

Sounds great!! Slightly going off topic but noticed you have the revolution induction system. Hear people saying it suffers from heat soak etc and wont get optimum power with it. What are your views? Do you notice any issues when the engine has been driven hard for long periods?

I've posted previously about the intake elsewhere. It sure sounds nice, but absolutely does get hot - especially in slow moving traffic or when stationary. It affects power, but by how much I'm not sure.

Really you only get one for the sound and looks - it does nothing for power other than cost you it.

What's it like running along does it drone? Started gutting my pre-cat but could not for life of me get the top nut on drivers side!

How do people reach this nut?

Honestly, there's somehow less drone now with the decat pipes than when I had cats and the cat-back milltek. Don't ask me how but that 2800rpm drone is far reduced.

Mike - I almost bought your tubi remember (in a roundabout kinda way!) and ... maybe that's for when I get bored of this - if I do! I certainly now want to hear one as although this is loud is not "tear your face off loud" like the rumore seems to be :D I love this sound so much. I guess if I could have anything, it'd be a rumore with valves so you could have it quiet if you wanted... Dreams eh!

Anyway - here's another video - this time with the open gopro case. :)
