cookiemonster Posted March 12, 2010 Share Posted March 12, 2010 Got the Decats fitted, and the sound is I know when i fitted the exhaust it had a settling in period, will these be the same? get an almost rattle like sound when its floored at the moment but everything is tight and secure Anyone had that?

Ian Posted March 12, 2010 Share Posted March 12, 2010 It will probably be the heat shields, I need to check mine over when I swap the Japsepeeds over for my new decats My car sounds like theres a rattle snake in the boot from about 1.5-3k RPM but you can only hear it from inside the car, it drives me nuts Quote Link to comment Share on other sites More sharing options...
cookiemonster Posted March 12, 2010 Author Share Posted March 12, 2010 yea its alittle annoying, where abouts are the heat shields? can only remember them being on the oem cats? Quote Link to comment Share on other sites More sharing options...
Ian Posted March 12, 2010 Share Posted March 12, 2010 I think Fiddy said they were towards the rear somewhere, sure he will point out where when he sees this Quote Link to comment Share on other sites More sharing options...
cookiemonster Posted March 12, 2010 Author Share Posted March 12, 2010 good news, ill pm him if not. Thanks Ian Quote Link to comment Share on other sites More sharing options...
dcash5 Posted March 12, 2010 Share Posted March 12, 2010 I think its just a feature of straight decats to be honest. Fiddys car doesnt 'rattle' till 4.5k above so I doubt its a loose heatshield. Regards Dan Quote Link to comment Share on other sites More sharing options...
cookiemonster Posted March 12, 2010 Author Share Posted March 12, 2010 hmm does seem strange that straight pipes would naturally make a rattle sound? surely it cant be the exhaust fumes making that sound through the pipe? Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted March 12, 2010 Share Posted March 12, 2010 i have a rattle with my HFC's after they were fitted, but it only happens at very low revs, i.e if i pull away in too high a gear etc. but apart form that nothing. so i'll check my rear heat shields as thats where the noise is coming from. (i think) don't forget also when swapping over to HFC/decats, most don't have the support that joins the 2 togther, so the exhaust has more flex than usual. i think the Berks were the only one that put a new one back in.

Chadwick Posted March 12, 2010 Share Posted March 12, 2010 ive got a decat with a k1 system im finding it overly loud , has your decat made it alot louder ? Quote Link to comment Share on other sites More sharing options...
sketch Posted March 12, 2010 Share Posted March 12, 2010 the k1 is too loud for most people before the decats... ive got TOPSPEED resonated decats and they dont rattle or rasp, couldnt be happier with them, i have never had or tried the non resonated pipes on a 350 tho Quote Link to comment Share on other sites More sharing options...
Ian Posted March 12, 2010 Share Posted March 12, 2010 K1 is way too quiet, not really that much louder than stock Quote Link to comment Share on other sites More sharing options...

I was thinking that the bracket might be making the difference, might have to custom make something just to protect the flexi's if nothing else Quote Link to comment Share on other sites More sharing options...
TADDY Posted March 13, 2010 Share Posted March 13, 2010 K1 is way too quiet, not really that much louder than stock Ian what system are you running? I want loud Quote Link to comment Share on other sites More sharing options...
Ian Posted March 13, 2010 Share Posted March 13, 2010 K1 is way too quiet, not really that much louder than stock Ian what system are you running? I want loud You sure? Gives you an idea of just how loud it is Setup at the moment is DC Sports headers, Japspeed decats (soon to be removed), Ichiba Y-pipe, GReddy singe exit exhaust with the mid pipe silencer removed. Exhaust & decats will be for sale soon, maybe even the y-pipe aswell Quote Link to comment Share on other sites More sharing options...
TADDY Posted March 13, 2010 Share Posted March 13, 2010 Is it started I LOVE IT!!!!! my cars only driven at weekends so whenever i get in it i want it as loud as possible do you think the single exhaust and decats would be louder than decats and a K1 or true dual?
