I had these made up by a local exhaust fabricator and the cats modded so I can slot them back in to the rest of my system if needed.
The sound is deep and not raspy any more at all like the old system I had. Still fairly loud but very usable day to da, Unlike my old chim where you could not hold a conversation at 70mph. The cerb is nearly silent in 5th, Give it some more RPM and
I am waiting for a new HD Camera to come, when it does arrive I will make a few videos for the sound

Does anyone have a pick of the underside of a SP6 with Cat's on?
I have no idea if mine is decatted, but can only guess it is from the noise and th size of the pipes, but I'm not sure how think the cat's are.
here's mine:
Your cat is still in it is the box at the very front of the engine.I have no idea if mine is decatted, but can only guess it is from the noise and th size of the pipes, but I'm not sure how think the cat's are.

Managed to take a pic when the car was up on the ramps last weekend. 
What decats are they? AJP on decats sounds like it has an entire firework display lodged up it's pipes.
replace with standard pipe, done locally. Now traffic hear me coming 50m in front of me, which
leaves them enough time to move out the way. My mate has a decatted cerb with 3" pipes front
to back, didn't stop him around Spa, and sounded amazing.

Thank you very much Scotty! Learn something new every day
Heaven knows how loud it would be if it were decatted
I am not sure if the sp6 has 2 cats or just one but i know for sure that one up there is a cat. The biggest thing i noticed when i de-catted my AJP was the in cabin heat has reduced so so so so much when stuck in traffic. Heaven knows how loud it would be if it were decatted
I went the silenced de-cat route to make it a little quieter, Still loud but as i said above great on a run not intrusive at all. Jhonno said:
I think I will be having a word with Kevin at Zero Exhausts to make up a system for me.. I'll be honest, I LOVE the noise mine makes, but every time I see an orificer of the law my bumhole does an impression of a rabbit's nose atm..
Just try not to make any police officers feel unwelcome here, they are very knowledgeable and often extremely forthcoming, which is very useful for us all.The current edition of Practical Classics features a 4.5 Cerb and the owner is a retired traffic police officer...
