Horizontal Rear Muffler on 306? - Bennis - 06-04-2013
Hello 306oc,
New member here from Australia.
I have a GTI-6 and the exhaust on it is pretty shagged. It has a horrible metal on metal vibration/ rasp that appears to be coming from inside the cat, and the rear muffler has been swapped to a straight through design and it is shockingly loud.
I plan to build a new system / replace the cat and rear muffler. I want the exhaust to be very quiet, as I enjoy the sound of the intake, not the exhaust.
Although this video is not of a peugoet, it is of a similarly sized motor. This is how I want my peugeot to sound.

The man in the video used a single cat, 2.25" piping, 16" resonator and a 24" horizontal style magnaflow rear muffler.
Imo it sounds great, and I also quite like the horizontal style mufflers you see on the older honda hatches. I was wondering if anyone has done this sort of setup on a 306. Obviously you would have to remove the spare wheel and fab up custom hangars.
Heres some better pics of the muffler setup I am talking about.

Anyone done this before?
Cheers

First off, welcome to the forum.
To be honest, i've never seen anyone do this to a 306 before, but theres always a first time for everything. The only issue i can see, is that you;d have to sack the spare wheel off to achieve this look. Other than that, give it a go! Always good to be different
And don't forget to get some pics up here if/when you do it.

Welcome along,
As Sao haven't seen anyone do it yet, also I'm guessing you'd be using the dtandard routing? If so the back box would go from n/s to o/s? And therefore bumper modifications as your exhaust cut out will be the wrong side

I would be using the standard route and standard bumper exit.
I would get a universal muffler amd have the piping routed like so. (red lines indicate how the piping would route back to the standard system).

Apart from this horizontal muffler idea, has anyone got a really nice, quiet exhaust on their 306 gti6 / rallye? Similar to the noise level in that youtube vid of the civic?
I want mine to be really quiet when im just driving normal. The intake noise is enough to satisfy me.
RE: Horizontal Rear Muffler on 306? - Matt - 06-04-2013
That's a lot of bends to have In an exhaust system, would be restrictive, as you want the gasses to escape as quick as possible
RE: Horizontal Rear Muffler on 306? - Dum-Dum - 06-04-2013
Welcome along ate.
A 6 will never sound like the car in the video cos its a honda and hondas just sound different.
Realistically for power you want as few bends as possible as short a run as possible and as smooth piping as possible (and silencers arent smooth).
If your just going for a certain noise take it to powerflow or whatever the aussie equivalent is and get them to make something to sound exactly how you want.
RE: Horizontal Rear Muffler on 306? - Bennis - 07-04-2013
The intake noise on that honda sounds near identical to my 6's intake noise. I reckon if I piped down the exhaust note it would be similar?
I have it booked into an exhaust place this week for them to look over the horrible rasp noise in my cat, Ill ask them about mufflers then.
I have some ideas I have borrowed from some other car forums as to another exhaust setup too that I will report back on shortly.

Might sound silly.. why not just get a new standard exhaust system? Then all you'll hear is induction
RE: Horizontal Rear Muffler on 306? - cwspellowe - 07-04-2013
+1
Standard exhaust systems sound pornographic. I'd imagine rare as rocking horse shit down under though
RE: Horizontal Rear Muffler on 306? - Bennis - 07-04-2013
I have considered the standard system, but I was under the impression they were pretty noisy from the factory? Has anyone got a video of a standard exhaust?
I only think this because I have heard a standard one in person and it sounded pretty loud but it could have been broken?
RE: Horizontal Rear Muffler on 306? - Piggy - 07-04-2013
the only reason hondas, mitsis etc have that exhaust setup is space...which you have plenty of on ya 6
IMO standard exhaust for what you want.
and hondas sound like that due to the mega high revs and likely vtec
RE: Horizontal Rear Muffler on 306? - Bennis - 07-04-2013
I'll look into standard exhaust. I'll post up a picture of my exhaust system tomorrow. I am not sure whether the centre resonator/muffler is standard or not. A new rear muffler is about $270-$300 it seems.
If anyone has a soundclip of standard exhaust please link, would be forever grateful!
RE: Horizontal Rear Muffler on 306? - cwspellowe - 07-04-2013
Any use?
RE: Horizontal Rear Muffler on 306? - Bennis - 07-04-2013
Does the S16 have the same motor as the GTi6?
The orange one sounds pretty loud, the red one not too bad.
I saw a video of a jetex exhaust and it seems fairly quiet.
RE: Horizontal Rear Muffler on 306? - cwspellowe - 07-04-2013
Jetex ones are pretty tasty to be honest, they did a group buy on gti6.com and a lot of people loved them
The European S16 was the GTI6 rebadged, basically, not to be confused with the UK's S16
RE: Horizontal Rear Muffler on 306? - Bennis - 07-04-2013
Jetex seems to be the quietest non standard option after a quick trawl through the forums. Might have to see if I can get one shipped over here. In the meantime I will see how much it costs to get a custom quiet system made up locally.
RE: Horizontal Rear Muffler on 306? - Piggy - 07-04-2013
what about a later turbodiesel or hdi back box?
they huge silencers
RE: Horizontal Rear Muffler on 306? - Bennis - 07-04-2013
Have found a supplier for Jetex in Australia, a couple hours from me too so thats not too bad. Hopefully they can price up a system. How much is a Jetex worth over in the UK?
RE: Horizontal Rear Muffler on 306? - cwspellowe - 07-04-2013
I think the group buy was around £300+ for a cat-back system ($450 in southern money)
RE: Horizontal Rear Muffler on 306? - Eeyore - 07-04-2013
ive got a decat, and sportex straight through race pipe and standard backbox. Sounds the nuts!
