Hi guys- looking to get a second hand sports/race cat(100/200cpi). I have read that the standard bore on the ST is 2.5? Is that right?
If it is right does that limit what sports/race cat I can buy, i.e. do I need a sports cat that is 2.5 too or can i go for say a 3?

Cheers in advance
Ps. if anyone is selling one too- let me know

as far as im aware mate they will all fit, the flanges where the bolts go through are all the same.

Also- at the moment im a bit concerned of the potential nightmare fitting a decat pipe- having read all about snapped bolts, and bolts in the turbo etc. Im therefore a bit concerned about getting a downpipe and may just setlle with a race or sports cat. I have read people saying dont bother doing one and not the other- but surely a race cat will provide some benefit even if i dont go down the downpipe route....

All help welcome

cheers

From what iv read the downpipe is one of the best things to do, although to see the full benefit you'll be better off fitting a sports cat at the same time to allow the air to flow freely etc etc

I guess fitting issues comes down to who does it, iv got mine booked in at TOTD on thursday and iv read good things about them and fitting downpipes.

If i was to go ahead and buy a 100 cell cat- surely i would experience some gain in power/response and or noise wouldnt i?
Who does the best value 100 cell or 200 cell cats? pduk? Or am i best waiting for one to come up second hand??

On that note is anyone selling a sports/race cat?????????

Is it 100 or 200 cell mate? I may be tempted but just a bit out of price range i was semi relying on one popping up second hand...
You know or anyone know of a second hand one for sale- i see they pop up from time to time?

Cheers
