Kaveney Posted February 2, 2016 Posted February 2, 2016 I have the below exhaust set up and it is very good but just a bit rasp on wot at 4000 rpm . It is nice but sounds more angry than exotic at wot . Dc sports 3-1 headers Art pipes ( de cat pipes ) Miltek y pipe Miltek center Miltek rear box I have been reading that a true dual exhaust takes away the rasp ? Is this true and how does this work Quote
Alex350z Posted February 2, 2016 Posted February 2, 2016 Not so sure, but i reckon its the de-cats giving you the rasp Some high flow cats maybe? 1 Quote
RobPhoboS Posted February 2, 2016 Posted February 2, 2016 Can you provide a video clip of what YOU would describe as 'rasp' ? A ridiculously loud Honda sounds 'raspy' to me, and our v6's don't but yeah as Alex said that's possibly the culprit. (although I thought those ART pipes didn't do that). Quote
Kaveney Posted February 2, 2016 Author Posted February 2, 2016 Was the same with hfc that I had on so was thinking the miltek may add to this as this is not a true dual system . Quote
RobPhoboS Posted February 2, 2016 Posted February 2, 2016 Can you sling a video up or find a similar example ? Quote
ZeppoJeff Posted February 2, 2016 Posted February 2, 2016 I've got a true duel and decats and I wouldn't say mine was raspy 1 Quote
Alex350z Posted February 2, 2016 Posted February 2, 2016 Miltek is usually quite a deep tone without rasp 2 Quote
Kaveney Posted February 2, 2016 Author Posted February 2, 2016 It's as soon as I changed the cats to hfc and then to art pipes . This may just be the way the car sounds I will try and get a sound clip . Quote

Jetpilot Posted February 3, 2016 Posted February 3, 2016 I have a true dual and hfc combo and pass Thruxton noise test, the strictest in the country at 90db, but have also done Castle Combe with Andy James, supercharged running full Miltek and it sounds gorgeous, not a hint of rasp. Quote
Kaveney Posted February 3, 2016 Author Posted February 3, 2016 Time to get spending again then Many thanks One last thing is the invidia Gemini true dual over loud as I did like the miltek for it was not over loud . Regards Alan Quote
davey_83 Posted February 3, 2016 Posted February 3, 2016 from clips online, ART decat pipe with the stock Z33 exhaust rasp's a touch. 1 Quote
Kaveney Posted February 3, 2016 Author Posted February 3, 2016 My HFC rasp just as much as the ART pipes do with the Miltek ? Alan Quote
ZeppoJeff Posted February 3, 2016 Posted February 3, 2016 Invidia true dual, invidia 60mm test pipes https://vimeo.com/154042710 Quote
blobbish Posted February 3, 2016 Posted February 3, 2016 My HFC rasp just as much as the ART pipes do with the Miltek ? Alan I have Cobra HFC's (well not for much longer) with the Miltek and I get rasp. It's worse when the car is cold. Doesn't bother me though, guess its a marmite thing. Quote
