Exhaust tips

[utb]

Hi guys! Okay, right upfront probably make sense to declare I am rubbish with cars… I love them, drive them and spend money for other people to repair them; otherwise I haven’t a clue…

I have noticed the exhaust tips on my 2011 23i are pitted and looking like they need to go to exhaust-tip-heaven! So, I have a couple of questions: how are they connected and what’s the best place to get a (aftermarket) replacement.

Thanking you lovely folks in advance for all your wonderful advice and help.

Hi, have you tried cleaning them up with metal polish?

Yes, they often do polish up well with something like Solvol Autosol.

Had a stage 1 detail today (bloke was recommended by a buddy and, I have to say, did a great job)… chap had a go at them but said they’re too far gone and he’d just strip them down.

So, I’m thinking to replace.

As I say, I’m a hopeless romantic when it comes to cars, so need some help!

Ah, that’s the sort of thing I was thinking of getting!!

Do the old ones just pop off? Or are they spot-welded?

Thanks, that’s very helpful. Even as a car-diy dis-enthusiast, I am suitably motivated to give that a go…. Wish me luck

Technically they just slide off but there may be years worth of gunk making that tricky so you may need a bit of a persuader.. i used a dead blow hammer at the back of the tips which also requires a bit of arsing around on the floor but its easy enough

Yep a good spray of WD40 and a bit of persuasion from behind with a bolster and a 10lb tapometer and it flew off

I used an oil filter wrench to remove my exhaust tips, something like this - https://www.amazon.co.uk/gp/product/B003AMVZWC/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

I then fitted these - https://www.amazon.co.uk/gp/product/B083R4RT9Q/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Ah they're not bad for that price. I was hesitant to get the carbon tips as I wasn't sure of the right inlet vs outlet measurements to go for (don't have an accurate way of measuring and nobody seems to know).

My tips came off with a good firm yank, no welds or screws. Its a 20i... the 35i tips are welded on.

This is the way I removed mine,slight twist and their off

 

[ajguk]

2009 30i here - are these welded on or will they come off with a mallet/filter wrench?

They should be removable like the 23i ones

Hey Jamie, looking at getting some similar tips myself. Just to check, did you go for 63mm in, 76mm out?
Cheers!

This is a revelation!! I assumed the tips were a permanent part of the exhaust and to replace would need a new back box. I’ve tried polishing our 23i tips but they haven’t gleamed as I’d have liked so will look to replace. Will give a good at ‘persuading’ them off… like the polished look but also taken by those carbon-esque ones too (will also hold on to originals, once off they may polish up better

Be careful... buy local not direct from China, so you can return if necessary :lol:
I measured the exhaust at 61mm, so I ordered the closest size which I thought would work, 63mm inlet, 76mm outside.
On Aliexpress I found these: various sizes available, so I did indeed order 63/76mm




Shipping painfully slow, but they finally arrived, and at first glance look pretty good, until........ da fuq?



Check the measurements I thought, indeed the inlet was 63mm, BUT... the bloody things won't go on as there is an internal step in the bore.
The stupid thing is that either side of that step, the bore is 63mm or 61mm towards the outlet. Absolutely dumb design, make sure the internal bore is the same along the length of the part before you buy.



Can't be arsed to return them, I'll redesign and reconstruct using the materials, so not a complete waste.
By the way, I was able to twist the original tips of by hand, eat an extra weetabix

I pulled one of the tips out on the 23i back in November.
It wasn't difficult, just came off by hand with a firm pull.

After:







Those edges are a bit of a problem to get into.
I need to pull them both out and use the dremel on them.

I took mine to a local metal polishers, worth salvaging. Ive got a cheap set on at present, £20 off amazon, easy to pull off and clean up with metal polish
