Shotgun exhaust
I know I have already posted about an exhaust but I seem to get one reply and then nothing lol. So this post should answer my ultimate question.
I have a full stainless 3inch system from turbo back. Two tiny resonators and one big back box. If I get a shot gun exhaust made up, twin pipes with no box will it be mega noisy? Or what is making my sytem so quiet? |

Back box is normally the deciding factor in noise levels. A big back box is probably designed to quieten things down, the resonators certainly are!
I have a Milltek system, non-resonated, the back box is not far off standard system size and is fairly subtle sounding compared to many other systems. If you were to run your car without a back box the noise would be pretty unforgiving! |

The size and type of the back box will determine the noise.

You tube rcm exhaust or that one scoobs world do, they both have no silencers and will show you how loud they are?
Each to there own and all that but why???? No gain there but to be really loud??? |

The bottom rear silencer is a nice, quiet Prodrive silencer that was supplied as part of the Subaru approved PPP. The top back box with a tiny silencer is a Cobrasport, much noisier and sounds great, personally I wouldn't have wanted it any noisier though. People have fitted the RCM team Ice system and then usually regretted it within days. Your current system is probably a lot louder than you think.

I had a vortex extreme for about 3 weeks. Anyone who came to the rolling road day knows how loud it was.

Yeah I also saw that one, did you have a full decat system? Was it continuously loud? Or could you make it abit quieter with low revs and high gear? Lol

Full decat, was too loud in the end, that's why it lasted 3 weeks.

Fair enough haha, it is really bad then? So Thats rulled out the shotgun exhaust! I'll have to have a look around for a decent back box
Thankyou for everyone's help! |

if want the next loudest thing try blitz nur spec there loud , cheaper vortex from scooby world there loud but not OTT

Both of those would do my head in personally.
I followed a classic with a Nur Spec in convoy to Japfest a few years back along the M4. It was getting on my wick by the time we got there, so it must have been much worse for the driver... he only swapped it over for the event and went back to something more sensible afterwards! |

I remember following Graham (Bandit) from Clackett Lane services out to Lydden a few years back when he had an afterburner extreme, gave me a headache and I wasn't even in the same car
I'd personally go no louder than an afterburner vortex, beyond that is just a bit silly imo. |
#14
|
||||
|
||||
that's why i run a H&S sport exhaust as nice and quiet but gives a good flat four sound

And don't forget that most UK trackdays are a 105dB or even 98dB limit! - You may even not get onto the Ring if too loud.
If you don't mind being pulled over and looked at by every perso on the road try on of these! https://www.youtube.com/watch?v=LZSB-Ixqq4w

I've got a mk1 Ninja on mine at the moment. I think it gives a good exhaust note and a nice burble. Its a little on the loud side but is just bearable. I would not want it any louder!
Aesthetically I would probably prefer the afterburner vortex though. The Mk2 Ninja looks nicer too but I've not seen/heard one fitted. |

Ninja 2 then Silly loud Vortex Extreme. Once it was off I put a Afterburner on, was a much better balance.

Yeah that vortex extreme sounds LOUD lol. Is it just one of those exhausts that you can't make be quiet no matter what?

I highly rate the Cobra 3" system with Sports cat only... Plenty Loud enough (other will vouch for this) and performance gains to being 3" and properly mapped.

3" doesn't always mean performance gains. Generally depends on the supporting components, not just the map I believe.

I can't remember the figure but 3' is required over a certain power level - I went 3' straight away on my first re-map of 275Bhp

But having 3" over 2.5" will be a good start for gaining more bhp
