Decat sound

[cookiemonster]

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]

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

[cookiemonster]

yea its alittle annoying, where abouts are the heat shields? can only remember them being on the oem cats?

[Ian]

I think Fiddy said they were towards the rear somewhere, sure he will point out where when he sees this

[cookiemonster]

good news, ill pm him if not. Thanks Ian

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.

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?

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.

ive got a decat with a k1 system im finding it overly loud , has your decat made it alot louder ?

[sketch]

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

[Ian]

K1 is way too quiet, not really that much louder than stock

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

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

[TADDY]

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?

[Ian]

yup

[dcash5]

Its a shame we have not washers in the bonnets then you could get some lights in them to get the full 'look' Ian - you chav hahaha

 

init!

[Ian]

Sure i could fit fake ones

[TADDY]

let me know when you come to sell the exhaust then pal, I have decats and a full true dual but if this is louder then i want it

[yokomo]

why dont you just get the mid silencers deleted from your dual ?
