Mike D'Silva Posted 4November, 2014 Report Share Posted 4November, 2014 Here's where I am with my 964 and exhaust so far... I ended up buying all 3 components... fabspeed cat bypass - pelican parts vertex primary bypass - ebay dansk g pipe (short i think). - pelican parts First step was fitting just the primary bypass pipe... Stock cat and stock secondary muffler... The sound was pretty much the same at first.. but after a while it seemed to get louder. I don't know how that is possible seeing as it is just a straight through pipe.. I must have been on some stellar drugs? Then I fitted the fabspeed cat bypass.. this upped the noise level again.. and is very nice. The note sounds like an old school porsche.. very traditional. But doesnt get exciting till 4000 rpm and in a tiptronic, that only happens in 1st and sometimes 2nd gear... or third if you are going nuts... Last night, i removed the primary bypass and reinstalled the stock primary muffler.. and fitted the Dansk final g pipe... The note is slightly louder again and sounds very different... not as nice as the primary bypass.. but here's the thing.. the car feels like it pulls much harder down low... am I dreaming? I managed to drop the stock primary muffler on my finger and now its about to fall off...(still throbbing a bit) Link to comment Share on other sites More sharing options...
Tit Posted 4November, 2014 Report Share Posted 4November, 2014 An exhaust thread with only a picture of fingers! Do you think there's any issues running a cat-bypass without any ECU mods? Not sure about the O2 sensor arrangements down there....the computer dosen't sense a cat-failure or anything like that? Link to comment Share on other sites More sharing options...
Mike D'Silva Posted 4November, 2014 Author Report Share Posted 4November, 2014 The fabspeed cat bypass still houses the stock O2 sensor so no warnings. My partner is trying to guilt me into putting the stock cat converter back on in the interests of the environment.. and I'm starting to agree...

Tit Posted 4November, 2014 Report Share Posted 4November, 2014 Does the cat bypass make the car smell? Link to comment Share on other sites More sharing options...
Russ Posted 4November, 2014 Report Share Posted 4November, 2014 Cat's normally have a 'lifetime' don't they? so i'd say by now they're not actually doing anything I always thought cat converters smelt worse than without Link to comment Share on other sites More sharing options...
SC 3.2 Posted 4November, 2014 Report Share Posted 4November, 2014 Mike,you may wish to run a small (sterilezed ) drill bit thrun your nail into the flesh to release the build up of pressure under your nail. It may throb all night and keep you awake. This actually does work. Regards Pete. Link to comment Share on other sites More sharing options...

Simonk Posted 4November, 2014 Report Share Posted 4November, 2014 I'm surprised it's not louder but I think it sounds nice Mike, particularly through the tunnel Link to comment Share on other sites More sharing options...
StevepGT3 Posted 5November, 2014 Report Share Posted 5November, 2014 holy shit... really? no i really dont want to do it.. If you set the drill depth so that it just goes through the nail you will only be drilling into the blood blister and you will not feel a thing, I have done it to myself at least six times Link to comment Share on other sites More sharing options...
J.J. Posted 5November, 2014 Report Share Posted 5November, 2014 wouldn't want to get caught without a cat, big big fine and just not worth the 1hp you might get by not having one. car sounds great by the way Link to comment Share on other sites More sharing options...
tazzieman Posted 5November, 2014 Report Share Posted 5November, 2014 My partner is trying to guilt me into putting the stock cat converter back on in the interests of the environment.. and I'm starting to agree... Crazy talk! Start a conversation about "food miles" or similar. Or travel guilt free by turning off your engine in CBD traffic. I'm being serious here. Or plant some trees. Certainly never ever travel by aeroplane Link to comment Share on other sites More sharing options...
chrisheal Posted 5November, 2014 Report Share Posted 5November, 2014 Car sounds great Mike... geez it was only over a year ago you were making me insulting offers on my 70' T and now we have both seen the light and drive tip 964's haha Link to comment Share on other sites More sharing options...
clutch-monkey Posted 5November, 2014 Report Share Posted 5November, 2014 nope- i have the full fabspeed system, and plug one exhaust outlet to stop droning on the motorway. when plugged it has more torque less top end. The note is slightly louder again and sounds very different... not as nice as the primary bypass.. but here's the thing.. the car feels like it pulls much harder down low... am I dreaming?

poli84 Posted 13November, 2014 Report Share Posted 13November, 2014 It's interesting to hear your car at full throttle being a tip. Maybe you are short shifting (?) but listening to it, I am left waiting for it to open up and start screaming. To my ear, there is such a noticeable difference at the shift sound between the two transmissions, the tip leaves me wanting for more. I'm running a Dansk G Pipe, sounds very similar at low to medium high revs, very loud outside of the car but really screams at WOT. Intoxicating, addictive and I love it.

hepkat63 Posted 19November, 2014 Report Share Posted 19November, 2014 Changed mine for the Fabspeed Maxflo dual outlet exhaust along with the pre-muffler catbypass pipe. I am more than happy with it. Quick and dirty youtube clip Link to comment Share on other sites More sharing options...
