Quickest pre-cat decat ever...
Discussion
Went over to my preferred garage today to get them to sort my leaky manifolds-to-y-piece and while I was there I said that I was thinking of getting the cats removed ...
"Well your precats are probably out already." came the reply "The cans have been cut open and rewelded ..."
A quick piece of wire shoved up the manifold through the manifold to y piece join later to confirm and bugger me - they're not there.
Oh well ... just thinking of getting the main cat chopped now but have been warned that it'll probably be a bit too loud if I do...

As I understand it, the Y piece and the main pipes/silencer are two separate sections. The Y piece contains the main cat, and removing it makes the noise much louder and rather rough sounding. Instead of removing just the cat, if you remove the Y piece and put a Clive F Y piece, or an ACT one, in its place, you will have more power but only a modest noise increase, so long as you leave the silencer under the car well alone.
Good subject for a chat tomorrow?

That is correct...QBee said:

This is what I'm told - but apparently replacing the cat with an inverted cone removes a lot of the echoey roughness... QBee said:

Much cheaper to pick up a decatted standard y-piece.

No, I meant a chat with someone who DOES know what he is talking about. I wouldn't be able to get more than six words out between coughs at the moment. I am SOOO pissed off with coughing 
LOL - I suspect that the remaining attendees assembled collective of testosterone and clanking nads might be able to string a few words together between us but hey...

You can weld a insert in the original cat ,like a funnel, this will stop that horrible sound .Other than that its clive`s Y piece or the ACT one .
Yup - as I said earlier ..."but apparently replacing the cat with an inverted cone removes a lot of the echoey roughness... "
De catted my manifolds earlier in the month and bugg3r me if it wasn't the nastiest wrist shredding pain in the balls drilling and hammering dust inhaling I wish I hadn't stared this job ever...
If you can get a third party to remove them for you go for it. If not then prepare for grazed wrists ahoy.....!
