Better Exhaust/Engine Note

[m1tch]

A suggestion is to look at keeping the exhaust the same but look to fit a different air filter/cone filter behind the battery - you will get the sporty induction noise but not the drone on the motorway etc if you pick an exhaust that is too loud.

I second that. I don't hear my exhaust (TTE) over the roar of my intake when accelerating. I have no idea what my car sounds like from the outside.

The intake definitely brought the smile-inducing noise. I did very much enjoy the rumble of the TTE before that,mind. But if it's a throaty roar you're after, there's nothing like hearing the noise that comes straight from your intake manifold.

Third on the above, similarly to what Shnazzle says, I've no idea what my car sounds like from outside etc. I know others have commented approvingly on group drives but all I hear is growl.
Another thing to think about if not already mentioned is the age/condition of your manifold, cat and backbox. Years worth of carbon and oily deposits can really mute the tone, maybe try some cataclean or similar to see if that makes a difference?

I've no idea what my car sounds like from outside

It, also, sounds nice
(but then you do the whole car park rev thing, and i think "hooligan")

Not true. Dales run. Your car smelled rich. I was getting high. But my ears were pleased. Oh, and Holy Isle run.

Ah! Forgot. I thought mine hadn't come out for a run in yonks.

It will smell rich with half my exhaust not making it to the cat hahaha.

How about cracking the back box open and removing a bit of the fluff inside?

Tbh the cheapest way of improving the sound of your 2 is swapping in a V6.

That only works at high rpm.
V6 sounds good even at idle

Sorry very busy with work and I put my plans on the back burner. It's now on the front burner.

A suggestion is to look at keeping the exhaust the same but look to fit a different air filter/cone filter behind the battery - you will get the sporty induction noise but not the drone on the motorway etc if you pick an exhaust that is too loud.

Interesting. Any suggestions on which? I've generally found it tricky to get things I want near me!

I've removed the stock air box and filter, and fitted a K&N RC2600 universal to a cutout of the airbox section that houses the vanes for the MAF and mates with the intake hose (apologies, worst description ever probably, someone else made the cutout if the air box, I bought it at Ding Day auction.) it sounds nice  . There's a few offerings from K&N, Blitz and AEM, more probably. Bit pricey for my liking though. Many have said though that stock setup better for temperature of intake air, and my particular filter is one which is cleaned and then oil applied periodically and I've read that the oil can eventually coat components like the MAF and lead to some degradation of the part. No expert here, just what I've read.

The K&N  ´oil´ is nor really oil and is should be applied ever so sparingly. If it gets byond the filter there is too much.
The K&N fliter cloth is not the main active part. As strange as it may seem, the meta gauze is. The filter works on electrostatics. Particles are attracted to the metal. The liquid is field enhancing medium. The cñloth collects the parts to large/heavy to be deviated.

The foam/oil filters also do nót work like ´filters´. They are centrifugal filters. The foam is of open structure and the air is forced to go through tight corners, which slings particels to the outside. The oil is meant to leave only a tacky surface retaining them.
So again; apply lightly and let it dry till you draw ´hairs´ upon toutching.

This observed; the OEM set up is the best. A twin layer tacky foam insert would be an improvement but best not mess with the rest unless for a véry specific goal. Even a longer inlet stub will cost more elsewehere than it gains in the higher end of the power curve.

I found tchanging to an open cat back the only way to really change the tune the car sings.
And the drone... ah well, drones are all the fashion :-)
No seriously, my motorcycle not-muffler drones seriously but changing up/down will sort that and I found the aerial more of a nuisance.

Out of interest I see the Remus links from last year are now dead on their site. I wonder what they did with any remaining stock?  Or if they just kept blueprints/jigs just in case of orders?

Even the newest TTE/Remus will be 10+ years old now you'd have thought.  Mine's already had a new flange welded on.

[shnazzle]

I wouldn't want another one. All said and done, yes they sound and look great, but they're quite bad. They're heavy as all hell and flow isn't particularly fantastic. Albeit more than capable for a stock 1zz.

Electricaly ´glue´ a motorbike one to fit and swap fro OEM for MoT

Just be cautious.
I have used the K&N and others gauze/oil or foam like filters in the past.  It seems that on independent tests they have shown to increase the amount of dirt that enters an engine.  I have confirmed this on used oil analysis and therefore stoped using them. 
Another issue with the oil gauze filters is MAF wire contamination with the oil vapor. This contamination will throw off the MAF reading and in time will permanently ruin the MAF. 
This has been widely reported which prompted K&N to respond to the allegations where  they mentioned it was the owners fault for over oiling the filter however it turns out that K&N was supplying the filters over oiled which made their point mute.

Because these filters became a widely known problem other manufactures like AEM and INJEN offered oil less filters that use cellulose material instead of gauze. The trade off was a little more restriction and shorter life before it has to be thrown out however its filtration efficiency is far better and almost as good as the paper. 
There is no free lunch when it comes to filtration and it's a trade off.

So what's your view on the TRD air filter? Same as a k&n?

There is basically no free lunch, period 

Also the OEM compromises in modern cars are só good, só well researched and developed that it is more than a rule of thumb that any inprovement in a specific area comes with more downsizes in others.

That said, I have a double layer foam filter in the OEM intake system. More as a Pavlov thing remaining from dirt bikes; TwinAir, PolyAir....

[Gaz mr-s]

Since this is a running thread I'll ask this.....the oem intake section in the rear wing is wrapped in 'polythene'.
Why?

Isn't the first section inside the inner wing made of some sort of fibrous/fabric material?

I can only imagine the fabric is noise insulation and the plastic is to stop the insulation from rotting
