lukeaJones Posted August 20, 2015 Posted August 20, 2015 (edited) is there a way i could get my gt ultimate auto with cobra cat back system and k&n typhoon filters to pop and burble? i have tried it with decats and all it did was go really raspy. any help please luke Edited August 20, 2015 by lukeaJones Quote
Alex350z Posted August 20, 2015 Posted August 20, 2015 (edited) Get it really hot? I have a cobra resonated system with standard cats and it pops and burbles. It is a manual though Edited August 20, 2015 by Alex350z Quote
fatrab Posted August 20, 2015 Posted August 20, 2015 (edited) Assuming you want a Scoobie-type burble, you'd need to play about with manifold lengths. Unequal length manifolds into a single pipe. Easy to do on a scoobie, not so much on a V6. Edited August 20, 2015 by fatrab Quote
lukeaJones Posted August 20, 2015 Author Posted August 20, 2015 yeah when its really hot i can just about hear a very quite pop lol the auto seems to kill it any ideas to increase the volume? Quote
Richie94gts Posted August 20, 2015 Posted August 20, 2015 I have a manual, intake and cobra non-res and I don't get any pops or burbles either. I was expecting a decat/hfc would sort that but from your comments it sounds unlikely. Quote
lukeaJones Posted August 21, 2015 Author Posted August 21, 2015 Yeah from what the decats did to my system I wouldn't recommend it but it personal preference. I like my system deep and would love a burble where as the decats made it very raspy. Would stainless headers help? I know they are supposed to be a nightmare to fit though. Quote

Ogman Posted August 21, 2015 Posted August 21, 2015 does the centre pipe have a silencer on it?! maybe try a straight through pipe if it has? Quote
lukeaJones Posted August 21, 2015 Author Posted August 21, 2015 does the centre pipe have a silencer on it?! maybe try a straight through pipe if it has? no there is only the back box on this system. i have previously had decats and short tails and still didn't pop and burble and that was ridiculously loud!!!!

Grundy Posted August 21, 2015 Posted August 21, 2015 Headers don't help, Tried and tested Thats with Decats and a full straight through system Quote
lukeaJones Posted August 21, 2015 Author Posted August 21, 2015 looks like its not going to happen then :-( Quote
dajw Posted August 21, 2015 Posted August 21, 2015 Mine burbles at idle and pops on over-run (even on the auto). I have the Motordyne art pipes and Ark GRiP system. I was told that an auto will never pop on overrun, but the torque tables plus map which errs on the side of richness seems to sort that out. To make mine pop is simple: hot exhaust, hold the revs high (about 3.5k or so) and just lightly go on and off the throttle. Pops every time. I suspect this might have a lot to do with the stiffer shifting from the torque management tables update in UpRev for the supercharger however. Quote
nissanman312 Posted August 21, 2015 Posted August 21, 2015 (edited) My invidia let's out a loud pop on each change when gunning it sounds kind of sounds like someones being shot lol Edited August 21, 2015 by nissanman312 1 Quote
dajw Posted August 21, 2015 Posted August 21, 2015 Nic he's got an auto - I understand it is harder to make them pop. Mine popped on the standard exhaust + decats, it's just better with the posh system. It didn't pop at all before the torque tables were fettled with. Quote
nissanman312 Posted August 21, 2015 Posted August 21, 2015 Ahh yeah I think he has my old cobra? 1 Quote
