The adjustable ones Tegiwa sell on ebay for the civic vti would probably fit or motobuild but they are a tad pricey

Not sure if they are worth fitting to a 120. A few have tried and found it was negative.

You will have to get it frabricated as the downpipe and cat is all one piece on the 120 so the cat doesnt just bolt it so it needs to be cut out and flanges welded on to the downpipe so a decat can be fitted.

I need a new flexi due to being low, So i thought de cat?? but if no good ill just replace the flexi pipe!!

Theres a lot of talk of fitting a decat to the kseries reduces backpressure although seems to be more of an issue with the vvc variants. Although dont expect any gains from decatting the 120. They can sound great, I replaced my flexi with a down pipe from a vvc as it has no precat then fitted a decat as well used to set off car alarms when parking in multistories. :laugh:

Will add gain on a 120 (not sure if it would be noticeable though), it's only the 160 vvc where it is questionable due to excessive back pressure.

Also isn't the ZS system on a 4 pot like the ZR where it has two cats? One in the manifold and then a cat pipe before the centre section that bolts onto the down pipe (manifold and down pipe are in one piece) so a decat pipe can be fitted?

i decated mine and must admit that i didnt notice a huge difference but what a noise! Multistory carparks have never been so much fun. The 120 has another cat at the mani but im hoping to change that soon.
