KTEC Stealth Exhaust Help...

[P17 TOO]

Had the Supersports version fitted today to replace my twin pipe Janspeed and it seems to be knocking when I hit any bad pot holes or bumps. Have had a play around and it all seems to be secure plus I also had new mounts centre and rear fitted so that shouldn't be the problem?? I've taken some pictures of how it sits if they help and the only possible place I can see that it might be hitting is the 2nd picture below. To me there doesn't seem much of a gap so is this normal?? Never really looked under the car at this point with my old Janspeed system so have nothing to compare this too! The centre pipe does seem to sit lower though but after searching I think this is normal isn't it?? Also looking at how my back box sits it seems lower to some so opinions on that to please...

Also my mounts that were taken off the car for the new ones didn't actually look as bad as thought they would so wondering if they really needed replacing just out of interest?? Everyone seems to say how heavy the stealth system is but it's definatly not as heavy as the Janspeed I had on and the mounts seemed fine with that on!

Thanks

Sitting way too low that matey! Mine knocks on the metal 'square' (outer bit) of the exhaust mount, as when it's sat in the mount, the rubber is so s**t that it sags right down and vibrates on the metal of the mount.

 

[Greeny.]

Mine isnt stealth either mate but its higher than that, to get it higher you will probably have to loosen all of the joints and twist the system. Myself and DannyR fitted mine in around 30 minutes with the car on ramps, my rear box litrally wont go any higher and it still shows and its the heavist thing ever!! Shame I got the fines for the Yozza race as it was a far better system but nevermind! x

 

[P17 TOO]

Thought so but still looks better than what I had on there! Is the only way of sitting it higher to make some type of custom mount that alot of people seem to have or should it be able to go higher with just the standard stuff??

Is the vibration something you worry about as when I heard mine knocking or vibrating I was kind of worried the exhaust might fall off!

 

[Greeny.]

The U bend should be sitting higher than it is as it looks like it might be hitting on the rear beam, but yeah I would put a socket in the rear hanger like most do, I have done the same as the hanger is just dogshit! I also replaced my centre one that ended up making sod all different with the weight of that system on it lol. You running a de-cat? It sounds epic with one

 

[P17 TOO]

No but my cat seems to have a hole in it as I discovered today when I was "playing about"!

Anyone offer advice on my new cat choices while I'm here?? Don't really want a decat due to MOT so obviously a standard cat or possibly KTEC Sports Cat but I've read these can be a bit touch and go when it comes to the MOT?!? Any other choices??

 

[Fred@BTM]

yeah get a phs1 cat = sport cat for peanuts

 

[P17 TOO]

Don't these only have one sensor hole though when I'll need two??

 

[richy22]

Y ktec system sags like a fucker too.

I replaced all the mounts etc yesterday on our 4 poster/drove the 2 miles back to work and the c**t os saving again.

I give up with it TBH

Lol, picture two clearly answers your question.

Suspension compress's, rear beam rises and kerbannngggg, the knock of a K-tec stealth.

Dogs**t exhaust system.

I got a 200 cell Powerflow Sports cat for £170 fitted if that helps?

na the later ones have 2 and are the same fiment as a phs2 cat

After a few tries my local Renault specialist managed to fit my Stealth exhaust very well with all the original rubbers. It failed catastrophically at first, according to them down to the clamps which are not suited for a stainless steel exhaust (stainless steel being harder than ordinary steel), making the whole system twist in the joints. They solved it by just tack welding the joints just so slightly to stop it twisting. It then took a bit of adjustment to make it not foul the rear axle. It does work, it just takes a bit of work.

Instead, my problem now is that original Renault rubbers can not stand the heat from the stainless system (stainless exhausts getting hotter than ordinary steel exhausts), especially when tracking the car, so the mid-rubber has half-snapped off after only one week. I've ordered the uprated rubbers from NWP hoping that it will help.

This exhaust has clearly not been fitted correctly. Slacken both the centre exhaust hanger and rear box band, push the system up higher and re-tighten. As the system rises up the hangers should rotate around the rear box and centre section, then once tightened the system will hang higher. It really is that simple.

Also:

Surround your middle exhaust mount with 2 cable ties around the entire block. This will prevent it getting stretched and warping later. "Pack" your rear exhaust mount by securing something in place under the "X" to stop it also sagging. A spare socket or a peice of pipe cabled tied in is a favorite method.

Honestly getting my Ktec to sit how i wanted took in total 3 trips to various garages and 2 sets of both exhaust mounts. Complete ballache to be fair and i have the recessed version instead.

 

[lemonnobby]

i fitted one of these and had to do some adjustments but as david said it all rotates when people just lift it up and down the doesnt work

 

[Clart]

They are fairly heavy and i had a few ghetto adjustments to make on mine. Socket in the hanger helps, and i've got it sorted with the help of some cable ties. Lift the exhaust with a trolley jack which makes it easier to adjust.

 

[richy22]

I have done what you have Clart...I have the socket only though and the fucker sags on the righthand side where you seem to have put that tie-wrap. No matter how tight I seem to do that band upit still slips after a few days.

Will get it back on the ramps soon and have another play though.

 

[.Kev.]

Who fitted that?

In your first picture you had the exhaust clamp pointing at 9 oclock. No doubt thats knocking the heat shield an sounding like a bag of nails. It would also give you another inch or so to play with so you can lift it up a bit, if you rotated it to 6 oclock.

Its s**t that you have to bodge and feck about with cable ties and other house hold equipment in order to get the stealth to sit right. The Renault one seems to sit fine without.

 

[TimR26]

Ktec fitted my stealth and it sits perfectly.

 

[.Kev.]

They also fitted mine, still had to use cable ties though.

 

[*Wilson*]

i got one about 2 years ago still got it, but mine bags on something always has. they dont fit the car very well im selling mine for a yozzasport exhaust or a supersprint exhaust

 

[P17 TOO]

Thanks for all the help, especially to David at Ktec for the little description that I printed off and gave to the garage

As you can see from the pic below the exhaust now sits higher and I'm pleased to say there aren't any knocks/vibrations anymore! I know it's not as high as some but I think without doing some customising to the rubber mount this might be as high as it's going, and to be honest it still looks 100% better than what I did have on the car!

On the cat issue while the bloke at the garage was sorting the stealth got him to look at the cat and it was found to have a 5cm crack so at the mo rather than buy a new cat it's been welded for the time being until it blows again/falls off!

Thanks again!

P.s...I know it might seem dumb but Ktec maybe you could supply some really fool proof fitting instructions or something with the exhausts as it seems alot of places have trouble fitting them...you probably find it so easy because after all you do make them

 

[TOGUSA]

just fintted the super sport stealth today and i couldnt belive how heavy that back box is, i managed to get it to about the same as above but it took some doing, i havnt adjusted any mounts yet but really had to fine tune it with the mid section.
just wondered how did you find the noise? i think its too loud to be fair

get a decat!!!! then just have the weilded up cat for when mot is due and you will save your self a few quid!! also the supersports sounds mental with a decat, well i like mine lol

 

[Cup_Phil]

Mine has started knocking

On track at FCS it knocked like mad around right hand bends - it does also sit quite low even with brand new mounts all round

That's still not fitted right you shouldn't be able to see the exhaust and hence why its called a 'stealth'.

 

[Clart]

I agree. The exhaust should not be visible. Get it jacked up and cable tied!

 

[Cup_Phil]

Mines visible - I'm not cable tying it - that's a proper bodge
It's started knocking on the beam going over bumps this morning too

It should fit properly with the standard mounts - not with cable ties too
I'll cut and weld the K-Tec brackets to make it sit higher before I start throwing cable ties on an exhaust lol

 

[P17 TOO]

I agree fuzzy you shouldn't need to cable tie it or put a socket in the mount to get it sitting right as after all it is made to fit with the standard mounts! Just out of interest how does one sit if it's fitted by Ktec who I'm guessing wouldn't use cable ties or a socket in the mount...is mine much different??

Like I said though I'm much happier with how it is now compared to when I first had it fitted and I don't think I'll be wasting any more time to get it sitting that extra bit higher...

TOGUSA yes to be fair it is louder than I expected but I ain't bothered as I like abit of noise! My problem might be when the wife starts complaining about it, but then again I could just floor it and drown her out with the noise it will make

As for decating I think that would even be too much for me!

 

[K-Tec Racing]

You should not need to cable tie or cut and weld any brackets to fit the system correctly. It will need a simple adjustment and thats all. Simply slacken the bolts in the centre and rear hanger, push the bolt up you have just slackened and the system will go up with it. Tightent the bolts and job done.

Cable ties are often used to reduce side to side movement, not to hold an exhaust up. For a start they would not be able to handle the weight of a system.

If anyone is struggling to get their system to sit up I will gladly have one of the guys here fit it correctly for free in around 20 minutes.

David.

 

[ForceIndia]

That's jacked up, touching the base of the car. Words fail me.

 

[K-Tec Racing]

If the centre section is not fitted correctly it will throw out the alignment of the rear box.

We have never had one leave us fitted that low.

Regardless, if the top of the backbox is touching the car, how exactly could it go any higher? Really?

Mine sits exactly how yours does in that picture but is hidden abit more due to having the ph-2 rear bumper, although I do have about an inch gap above the back box. Not entirely sure why some sit differently than others :S

 

[K-Tec Racing]

They all come out of the same jig and having sold literally hundreds of these we do not seem to get many fitting issues. The ones we do see that are hanging down have simply been fitted wrong and need a simple bit of adjusting.

This is exactly what happened when I had the damn thing. At the time I asked how it can possibly go any higher (given that it's touching!!) and you declined to answer!!!!!!!!

 

[K-Tec Racing]

If someone has an issue with one of our parts we will look into the problem. If you did not receive an answer I can only assume I did not receive or see the question. How long ago was this exactly?

If the centre is not fitted right the rear of the box could sit high (in your case touch the underside of the car) and this could point the other end of the box down, making it look like it was sitting too low.
