182 exhaust manifold to fit 172

[205gti6m3clio172]

As title, fitting a 182 exhaust manifold to my 172. What I need to know is what do I need to fit between the manifold and rest of the exhaust system. I'm looking to fit a ktec stealth system at some point and may be open to a decat suggestions. Just curious to see what other people have fitted. Thanks in advance

Ktec do a link pipe. I have also made the original 172 cat fit.

Yeah I have the ktec de-cat pipe.
You could buy a sport's cat but they are expensive.

Yeh don't buy the cheap eBay one. The angles are all wrong and usually leave the exhaust pressed against the shell.

Ah, you managed to get the 172 cat to fit? Is that without any mods/cutting? That'll help with the mot! Ok, so ktec link pipe is the way forward. Cool, thanks

Needs cutting and welding to make it fit, handy to have come mot time.

I used a k-tec decat pipe as a template, then cut the old cat up and re-welded it to fit.

now I can switch from cat to decat / decat to cat quick and easy!

It's worth bearing in mind that in less you modify the cat, fit a sports cat or have a friendly mot guy you will have a absolute mother ****er of a job once a year. Swapping between mani's and fitting and removing 172 cat ain't fun lol.

manifold was a 3 hour job on the driveway.
at least with the 182 manifold, cat swaps are quick and easy.

Cat change on a 172 mani is horrible. If he doesn't get a cat to fit the 182 manifold he will need to change the mani to be able to have a cat in place come mot time.
