K-tec exhaust

[Stuartwilkie]

Bought a k-tec un-silenced ultra performance exhaust and de-cat the other week there, but it seems to keep blowing at the join between the de-cat and centre section, anyone else had this problem? Is there some sort of different clamp i should use?

Thanks

That's unusual for them.

Is it a v-band clamp? Check all your exhaust and engine mounts are good then use some RTV sealant on the problem joint.

I just used the clamp that was on it already mate, is that a v band clamp?

Does it have a v-shape to it?

Something similar to this?

the standard olive joint is pretty crap, i sold my decat and bought a sleeved pipe to fit into the center section, much better.

however for your problem when i had the same joint as you i bought some black silicon thats heat resistant and put loads of it around the olive joint and then clamped it up at tight as possible.

dont use that fire putty or whatever its called these days, its crap, set brittle and then as soon as theres some movement it crumbles off.

No mate it doesn't look like that, think it's the standard one from Renault that's on it

Think i will just take it to a local exhaust place and get them to sort it, can't be bothered with the hassle lol

Had the same prob with the ktec clamps the nuts would not fit straight so they would not tighten up , picked up some from uni part
done the job

Black silicone RTV is great for sleaing up exhausts

I always fit new, re-used clamps never work properly as they change shape the first time they're tightened. I also use genuine as for a few quid extra, you get a much better quality part than a motor factor clamp (which usually strip the threads on the bolts before being tight enough)

you have a 172 so you don't have the same join or clamps as the OP.
