Exhaust dilemma

[Cup_Phil]

I had a K-Tec stealth on my car but after fitting the ITB's and the car getting a tendency to spit flames I wanted something that actually stuck out - so I swapped it for an Oreca Group N system (2.25")

I had a 200 cell sports cat made up for it and all was well - passes emissions tests for MOT easily, it's REALLY light and fits/looks good
However - it is actually killing my ears. On track days I'm wearing ear plugs and a helmet. Driving it back from Anglesey for 4hrs on the motorway was hell - had to have headphones in with iPhone on full to drown the noise out
Measured at over 110db inside with windows up
It's also measuring about 103db outside with the 3/4 rev test which is obviously too loud for a lot of track days too

I've also noticed I'm starting to get ringing in my ears the day after track days so obviously I need to sort it out

My dilemma is - do I chop the oreca middle pipe and get another 2.25" bore silencer fitted - like along motorbike style one, OR do I just sell it and get something else
If I mod the oreca to have an extra silencer am I completely ruining any re-sale value it might have?
I've already chopped the tailpipe down on it as it stuck out too far lol

Been looking at the K-Tec recessed system - it looks really nice and doesn't seem too loud but I've got a feeling it's really heavy like the stealth I sold

There really aren't any good options for Clio exhausts
My other issue is that the sports cat was made to fit with the oreca and it all fits perfectly - so I'm worried if I sell it and get something else that it won't just bolt on - the sports cat might be too short or something (I've got a 182 manifold as well btw)

Any recommendations?

Yes imo

Can you not get a silenced center section made up that will fit in?

 

[Cup_Phil]

I could get a silencer made that would clamp on rather than weld on - and then keep a straight through pipe that can be swapped back in - bit pointless though as it's way too loud straight through

Sell the Oreca and get an exhaust made up for your likings. I'd go for 2.5" diametre aswell, especially running on bodies.

 

[Cup_Phil]

The problem with having an exhaust made up is you don't get mandrel bends

Need video clips of flames and 103db noise

LOL I've only got vids from inside on track - I was hoping someone would post some vids of it from trackside but not seen any

 

[Cup_Phil]

I'm kinda considering buying this
http://www.jjcraceandrally.com/race...me-racing-stainless-steel-repackable-silencer

I can chop the exhaust myself and slot that on with some o-clamps.
It's re-packable so in a year when it's too loud again I can just open it up and re-pack it.
It's pretty cheap too!

Btb stealth. Heavy yes, but quiet in a stripped out car. In fact i find mine excellent. Definitely the best choice I made!

 

[Cup_Phil]

I'd love a BTB - but very heavy, very expensive and I don't like stealth exhausts lol

I've bitten the bullet and booked her in tomorrow lunch time to have another silencer fitted to the middle pipe
I know it probably makes the oreca worth less if I ever sell it - but I love the fit of the exhaust, just want it quieter. Hopefully with another silencer I can keep it for another few years

I had the oreca group N on my old 172, I also ran the decat Can't you just have a new middle section made up to fit the oreca backbox an you custom cat? The oreca bacbox is a sleeved fit so will slide over your new section an then all you need is a flange that is compatible welding to the mid section. Saves chopping your oreca middle section too.

 

[Cup_Phil]

Too much work - the oreca middle section is a straight piece of 2.25" pipe - easier to just chop it and weld a silencer in
No point making another middle pipe with the bend and trying to make it join the back box

Was yours stripped out? Cos honestly this thing is deafening lol

Piper

 

[Cup_Phil]

Yeah I know what you're saying mate - and after being in my mates Civic running a piper exhaust I'd kinda agree

But I've run out of time/money lol
Donington next sunday, my car won't pass noise tests and I don't see me selling the oreca and ordering a piper and getting it fitted in under a week

It's one of those things like the Billies that I wish I'd researched more before buying - as I probably would have spax coilies and a piper exhaust now lol
Oh well live and learn

Nah mine weren't stripped matey but it was still loud, next I'll be going for a piper like Danny said. I had a full system on me old Saxo including manifold an decay an it weren't as anti social as the orEva
