Lightbulb 330D custom exhaust system, advice/answers

Hi


I would like some advice on my 330D 07 plate

It's got a Dpf removal with a remap, I've had it 4 years now and am interested in adding some flavour to my driving. Yes am a old member I do more reading than posting unfortunately.

I would like a custom exhaust setup done, and also some advice on this too.

Is a straight pipe from the Dpf down to the exhaust tips my best option for increase in sound and slight turbo spool? Getting rid of both mid and back box?

Once I have done a straight pipe I would like dual or quad tips at the exit, any recommendations on who to visit to carry out this job in the uk, I am based in London but willing to travel to receive the best work done possible.

Once my exhaust system has been done, will I need another remap regarding back pressure and how will it effect my current setup?

Remap was done by more-bhp ages ago and to be honest I been happy with it since. If another remap is required, any recommendations on performance maps in uk?

I've seen a lot threads like these and general consensus seems to be you'll struggle to do anything to improve the exhaust note of a diesel. Sorry.

Also, you'll probably get the same answers as in the other ten threads you started.

This doesn't sound too bad >>>



Message the guy and ask what he's had done, but it's a diesel, there are limits

Start with a straight pipe.

See what you think of it.

It might be too loud or have a bit of a drone in which case you can have a silencer added in.

Theres a few 330 or 335d's on ebay with aftermarket exhausts and no DPF's and they usually sound pretty good.

Cheers guys appreciate the replys, any recommened places in uk that do good exhaust systems?

And if i put a straight pipe silencers will be deleted meaning this will log an error right? And will require a remap or just a delete on ecu?

Thanks

If your car was mapped with the DPF in place, it will need remapping, other than that it won't need doing again.

As above, the ECU wont care about silencers

So long as the remap has already been done to suit the DPF removal it'll all just work.

I have come up with two options so far,

http://www.styledynamics.co.uk

http://www.fastlanestyling.co.uk

Anybody used these guys before? See I have a good mate who can do the straight pipe for me the ones you buy from ebay decat straight pipe but I want a good finish with the tips such as quad exit so I need a trusted exhaust specialist who can carry out this job.

If you got any other recommendations please add. Thanks

And as a side note, how we'll do the 330D do with stage 2 remaps? It's a manual pre lci, I heard good things about Eco tune on here anybody advice me to visit them for this ?

You've already got a "decat" if the DPF has been removed. The cat is part of the DPF.

The rest of it is just an exhaust.

You'll get somewhere around 300hp with DPF delete and an exhaust with a decent map.

I cant give you any suggestions for where to take it, as i dont live anywhere near you. Just need to find some local places then find some reviews online. Many places will have pics of their work on their website or facebook or will let you see work they're doing if you pop in and enquire.

I just booked an appointment with fast lane style, they quoted me 450 for the exhaust system setup, straight pipe and quad outlet 2 on the left and 2 on the right, am going to see if i can get quad in the middle. But he said their might not be enough room under the boot, and this will obviously cost me abit more since i will require a new defusser.

Going to go with this job and then ill post pics of how it turns out. Thanks for replys guys.

If you buy a 335 boot floor panel, that will give you more room to do the tailpipes the way you want them.

One like this:

Thanks guys for replys, so it seems with my boot space i cant do this custom job, i probz push the quad exhausts to the sides, two, two on each side should be ok, straight pipe from dpf down to exits should hopfully do it.

When you've had the exhaust done post up a vid if you can..

Im considering doing the 335D exhaust but not sure if straight pipes would b to noisy for everyday driving...

Just get the 335 panel, it just bolts in, and gives you all the space you need for 335 or M3 style quad pipes.

If you get the 335 panel, can you fit an OEM 335d exhaust to a 325d / 330d?

Is there any differences with either the panel or the exhaust between the estate and saloon?

yes, you might need to buy and bolt on some extra hangers, and you'll need a reducer right at the front end as the 335 DP is 3" and the 330 is 2.5", but otherwise it'll all fit just fine.

Saloon and Estate exhausts are the same. Coupe and convertible are also the same, but different to the saloon/estate.
