Klarius exhausts - are they any good?
 

CarParts4less have got 17% off this weekend.

I'm pondering a cat back Klarius exhaust but I don't know if this is a decent make. Any thoughts?

Centre section - https://www.carparts4less.co.uk/cp4l...7f430ed&000430
Back box - https://www.carparts4less.co.uk/cp4l...bb80cb1&000536

That works out at £88.39 with the 17%.

:shrug:

I've got one on my ZTT..
Seems OK for the money and a decent fit, obviously not the same quality as factory fitted but then that seems general for most parts for these cars now. I suppose that if you are looking for top quality then go custom stainless.
Cheers Ian

Where did you get yours from Ian? CarParts4less?

Yes it was about the same price with free delivery.

My original exhaust back-box lasted 10 years :}. I replaced it with a klarius which lasted about 7 years :}, and have recently replaced that with an unknown brand which I am assured is Timax in disguise :shrug:.
The Klarius was good value for money at the time .

Go for a custom stainless stell, like those of MIJ Exhaust. I've got one, the whole line, it's fantastic & not at all noisy.
A tad more expensive but a no brainer, and that will last at least as long as the car, maybe longer... I prefer to pay once only & drive quiet no limit. :shrug:

Thanks Chris. The Klarius is pretty good value now at £88.

I've actually got a Bosal back box which I never fitted. I'm just wondering whether I should try using it with a new Klarius middle section** - or just buy both Klarius bits and ignore the Bosal. :shrug:

(** The Bosal and Klarius might not join together too well).

It's a question of £££s really. If you don't mind me asking, what did the MIJ stainless cost you?

By "the whole line", do you mean the cat as well?

Bosal is a major muffler manufacturer (not saying it is equal, better or worse than Klarius), so why not just put it on since you have it. If it was meant for your car then the inlet size should match your pipe.

Cheers,
Glenn

Very good value for money.
Besides I agree with you, it's a question of £££ but if you think of it closely not that much for a whole device that should last long & make you happy & quiet.
It's just a question of spending only once maybe a tad less than you might have spent on the long run in 2 or three swaps as it appears within the posts above.
EDIT: I haven't got any shares in the factory...

You're probably right - I'm just a pessimist! (i.e. if it can go wrong, it definitely will :D).

That's less than I was expecting. It does look a bit tasty :drool4:. Wish I hadn't seen it now!

PS. How close to the rear bumper are those twin tail pipes - they don't curl downwards like the ones on the factory back box.

I'm over the moon with it.
Here are two pictures of Lady Carlotta fitted with it:

It's a no-brainer for me ; go for it :}

Very close indeed, but no harm at all.
The evidence is I added the genuine but modified heat shield several weeks later and I didn't see any damage on the bumper.
I should add that with ethanol smoke may be a bit less hot (Coolant is 82°C instead of 90°C and the the upper engine is actually less hot as well).

It certainly is money-wise. I've seen the stainless now though.

Aaargh - can't decide!

Airflow is probably improved without the curly bits - the chunky straights do detract a bit from the overall look of the back end though (IMHO).

Still can't decide!

Btw, Lady C looks pretty rust-free underneath - must be all that fabulous south of France weather. :drool4:

Derestricted air flow indeed along the whole line: that's why I chose MIJ Exhaust, likely sensibly improving the throttle response, with a derestricted air box as well (trumpet off & 7 holes made in the box + K&N filter added to ethanol higher octane value - 105).
You're quite right Simon, my pride & joy lived her first 13 years in the warmest southern area, between Mediterranean sea & Pyrenees mountains, close to Spain.
And since 2017 sleeping in a comfy garage away from rain & moisture if any.
The challenge is: which of both of us will live the longer? :D

If it's an original Bosal (i.e before they went belly-up around 2013) get it fitted! They made the original exhausts for our cars. I'd been hoping Jezza would have had the supply of quiet, stainless, Chinese sourced exhausts sorted by now but I was desperate (MOT next Saturday) and had a GT Exhausts back box fitted last week. It looks like good quality and has a 2 year warranty but it is so boomy at 2k revs that I won't be living with it for long!!!

I bought it in 2013 so it might/might not be original Bosal. It doesn't have the 4 'ribs' (visible on #10 in the diagram here) but it could still be a pre belly-up Bosal.

If it helps I bought a Klarius 705751311 back box in May 2015.
After 4 years it is still fine. ;)
I got mine from ECP (same lot as carparts4less) for £47.99, so I think they are a bargain for what they are. :}

Any rust showing on it yet Bob?

I've just taken a couple of shots for you:

https://live.staticflickr.com/65535/...8a6aa608_c.jpg


As you can see a bit of light surface rust, particularly in the weld area for the tail pipes.

I think it is not in too bad nick for the price and time it has been on.

Thanks for the pics Bob.

Is it worth slapping some high temp exhaust paint on it? Something like this perhaps - https://www.amazon.co.uk/Galvanising.../dp/B019WRX166 (no idea if it works!).

To be honest it looks worse in the pictures than in real life.
To get the paint on the top I would need to remove it and it will probably eventually rot from the inside out anyway.

At the price, I will leave it on until it needs replacement.
I am not expecting it to last 15 years like the original one did. :D

I wish you could still get those!

Was that for your KV6? If so were you reasonably happy with the noise levels inside and outside the car? Looks like what you got hold of in 2015 is still available at approx. +£8-10 more. I want a nice quite ride so if you can assure me that's what you get then I'll be going for a Klarius like your's

Hi John,
Yes it is on my KV6.
I actually had it fitted with the intention of it being a temporary measure, with a plan to get something decent. I could not see that it would be much cop for the price, but needed something quickly as the original one was blowing.

I am pleasantly surprised with it. To me, it doesn't seem to make much more noise than the original.
For the price I can't see how you can go far wrong.

20% off now - code MID20

Klarius backbox I had fitted to a tourer I used to own made a louder noise than the original and not just when accelerating, it was present when cruising. Also the backbox is slightly deeper in profile so is more visible when looking from the rear.

They are cheap to buy though.

Well, I bought the Klarius and I can't get it to fit inside the Bosal without opening out the latter's split section. At the moment the Klarius is roughly half a millimetre too big.

Klarius O/D - 56.92mm
Bosal I/D - 56.37mm

Hmm, not sure what to do. I don't want to open the split and put a kink in it.

:shrug:

Take the new Klarius to an exhaust shop and have them stretch the inlet to the OUTSIDE diameter of the exhaust pipe so that will fit INSIDE the new Klarius.

That's what I would do. Actually, I would buy the exhaust pipe expander tool and a big hammer, cut a couple of slots in the Klarius AWAY from the slots in the pipe and make it bigger myself. It feels really good to hit something with a big hammer sometimes. :D A little muffler cement will then help it fit together and ensure no leaks.

Edit: Hmmm, looks like the newer ones have taken away the hammer fun. https://www.canadiantire.ca/en/pdp/o...-1250045p.html

Cheers,

I don't think the exhaust centres over here would want to do the stretching/expanding work - they'd rather sell me one of their own systems.

That expander tool might work, although it's got some pretty mixed reviews (not strong enough etc) - here it is on Amazon UK https://www.amazon.co.uk/Toolzone-Ex.../dp/B002R33Q9K

Even if it is strong enough, there's a good chance the expander will tear the pipe open. The Klarius has two slots cut into the inlet pipe (similar to the slots visible in this pic). Expanding the pipe by force is likely to cause a tear starting at the closed end of each slot - that will just make matters worse. I found some videos online showing the expander tool in action - none of them show it being used on a pipe with slots. e.g. https://www.youtube.com/watch?v=0ax2UbCst2Q

Edit: Here's one but I can see any difference - https://www.youtube.com/watch?v=CJWtducrohA

Do what the guy in the last video did. It will work. It won't split the pipe. If it doesn't stretch quite enough or easily for your liking maybe heat the pipe with a propane or butane torch and continue.

I need to expand it by 0.55mm plus a bit for clearance - let's say 0.75mm total (0.03 inches). I suppose it's worth a shot. Heating it would definitely help as long as I don't grab hold of the hot bit by mistake - ouch! :eek: (look where his left hand is at 2m 42s).

:D Once burned, twice shy! I predict a successful installation. :}

Cheers,
Glenn

I'm more inclined to the "if it can go wrong it will go wrong" approach. :D

You were right Glenn (much as I hate to admit it :D). The pipe expander worked a treat even without provocation from a blowgun.

I've expanded the Bosal pipe by about 1.0mm - it' would probably go to +1.50mm quite easily but there's enough clearance as it is, so I think I'll leave it there.

Now for this little lot. :eek:

Excellent! Nothing like a happy ending :D .

With the advice of TC and the others I'm sure your next job will go fine, too.
