I liked the sound of mine but I want it too be a little louder but don't want to buy a new system.

Anyone done this in the UK??
How much did it cost you?

Is it legal?
Will it pass the MOT?
How much did it cost?
Where did you get it done?
Will it be TOO loud?

I have watched videos and I cant really judge if it's too loud or not :headbang:
 
I can supply a modded original box that sounds epic.

A backbox delete is way too loud and they drone like hell, my boxes don't..

See my thread here ;

I've done about 80 for forum members now.

I've had mine done. Love the sound. It doesn't drone that bad at all, can hardly hear it at 80mph. But depends on what engine you do, from my understanding n52 drones less than m54.
 
Yep, highly recommended. Mikes modified boxed really crackle and pop. The only trouble is you won’t get as many miles per gallon as you keep wanting to drop it a gear to hear it sing :driving:
 
I had mine deleted, and piped back to slightly larger tips. I’d highly reccomend it to someone that wants to let a bit more sound out. I have an N52 2.5si and it doesn’t drone, it’s just a lot louder when sat at about 3k - but it doesn’t get in your head if that makes any sense at all.

The crackles, pops and bangs are off the chain and people do turn to look what’s coming. It doesn’t sound like a tarted up Corsa.

- yes it’s legal (if you want to track the car I imagine it would fail their own noise limit tests)

-I not Long had an MOT and it passed with no advisories. MOT does not test for noise.

- cost mine was 230 custom machined tips and stainless pipe.

- I got mine done by ‘Hastings Classic Custom exhausts’

- Not too loud for me, although I am a 23 year old who likes tinkering with his car. Many people would frown upon doing anything other than oem. Only you can answer this once fitted and always add a small muffler.

As mentioned above the earlier cars are supposedly more prone to drone due to a different exhaust set up. I’m sure mikes box would be a perfect middle ground if your weary of a full chop out being too loud / droney

[edit] as you have an E86 you would have the quieter back box delete as the E86 has the later engine / exhaust.

Noise - loud but doesn't drone on the motorway.
 
I'd go with Ducklaview's modded back box if I'm honest.

I had this done to mine, and even that was too loud / droned too much for my liking on the motorway. And that's with a teeny inline silencer.

The previous owner of my coupe chopped the backbox off. After picking it up and driving it home i already knew that I'll be putting one back on pretty soon. I must admit it sounded pretty cool for a bout 10 minutes, especially when outside of the car. I had a bit of fun with it for a few weeks until I had a new one fitted. But driving with it was not a good experience at all, especially with daily motorway use - it would drone massively at any speed past 60mph. It was VERY loud, even when at low RPM going five miles an hour and would pop constantly, which was pretty fun at first but got irritating as it would happen under any amount of deceleration. I thought the sound itself was boomy and shapeless - not a particularly nice exhaust note. All in all, it made the car feel 'cheap' to me and actually made it feel slower because there was a whole lotta noise for very little movement.

I recently had an Eisenmann Sport exhaust fitted that sounds fantastic, doesn't drone and has some very nice looking tips too.

In the end it's really up to you and how much/what type of sound you're after. If you have the means, it's definitely worth experimenting with a delete. Just keep the original backbox in case you don't like the result.

jesus cant belive peeps have paid circa 300 quid for a couple of bits of pipe welded in!! that's the cost of a custom fabricated backbox!

up north prices seem so much cheaper than down south lol, literally had quotes from 4 places all around 300 mark :thumbsdown: I knew I was getting done but went with convenience of having the exhaust place next to my work xD
 
I knew as soon as I did my back box chop on my old 3.0si coupe that I'd made a massive mistake. It droned terribly, the boom in the cabin between 2-3k rpm under load was awful, and it popped and banged all the time, which was novel for about 5minutes but just became ridiculous thereafter.

I couldn't get it returned to stock quickly enough!

For my money I'd be doing a ducklake mod, or indeed doing what I ended up with which was a standard rear box and midbox removal - the latter I can confirm was perfect (for my taste) in terms of zero drone, a bit more rasp and a bit more volume without losing tone or being too asbo. In an ideal world I could definitely have gone louder but I just didn't want to risk introducing any more drone. The modbox removal and replacement with straight pipes cost me about £60 at the local exhaust place back in approx 2017-ish from memory.
