Depends what else you have on the set up?

Think I'm running cat by pass and main silencer and am 104db static....which can get you at Oulton and the likes where they are pretty strict. Driveby is ok.

When I had the cup pipe on also I was 109db!

Some people run cat bypass and cup pipe and seem ok?

[sambaman]

got the main centre box of the car was just thinking of putting the d-cat on...carnt make my mind up

[carreraboy]

Cat by pass and cup pipe should be 105db.....cat by pass on it's own should be about 101db...cat by pass and cup pipe and g-pipe runs in excess 115db glorious....but no 964RS the same drilled airbox worn baffles all add to the mix...

[sambaman]

so Des...do i do it or not ???????..has mel had a word about the 64rs anniversary t-shirts and sticker for me ????said he would get onto you for me ... ;-)

My '64RS seemed to rev that much more keenly after it was de-catted - and it sounds GO FOR IT!

[carreraboy]

Every 964RS Should run cat by pass and cup pipe releases ponies lets the car breathe and sounds great but may restrict some very anal track days...I run straight system for Spa earlier in the year in a Clubsport, pardon what love ....

Out of Shirts and stickers Sambaman.....enough interest will print some shirts, I can let you have a couple stickers off my car, when we meet..

Are you actually going to tack the car? and where? Get the d-cat fitted and get noise test afterwards. Have you tested noise level as it is - johnny must have a tester surely...

thanks jamie....i have actually ordered the D-CAT pipe today..so i will let you know how i get on..already have the cup pipe fitted....may sound too sexy to quieten down ;-)

[anonymous-user]

d cat and cup mmmmm

ah i stand corrected... apparently the red baron's on cat bypass and j pipe with standard centre box to keep dbs down at high revs... sounds glorious but too loud for most circuits

Get em done! I've got the D-Cat and the cup pipe and it sounds great!.....Was running with G-Pipe as well but wife made me remove it as neighbours were giving me funny looks!....Lightwight party poopers!

Keith, it's my understanding that most 964RS are running Cat bypass and rear silencer Cup bypass pipes --- giving around 275-280bhp ?

I am not aware of wholesale rejection on track days due to high noise levels --- infact it's not something I have previously come across.

Both of my cars are so specced, neither sound noisey by comparison to the GT3 standard exhaust ...

But dB without meter readings, I'm not sure if that helps.

Only other option I would suggest is running an e-cut out style valve you can get them from the states for about £100 plus fitting for decent ones, DMH Performance are good and heavily over engineered plus they will allow you to run quiet or silly loud at the flick of a switch, they may add a little weight and you will have to cut part of the exhaust to fit but a decent place will do a good job, either weld it or use some mikalor clamps will be sufficient

i have d- cat, twin exit and sport final box, same as having cup pipe and i was goin to put gpipe as well but was told by german tuner that to get max power from 964 rs was to have both cup and de-cat and sport back box and mine goes great and sounds the dogs...go for it,with a remap 295 bhp,i have hot film as well 305 bhp

[sambaman]

put the D-cat pipe on carnt really hear or feel much differnce to be honest......except its all over the place on idle....took lambda sensor off and replaced it with the part from porscheshop ....off to specialist cars to get it on computer....good old Micky J ..will sort it ;-)
