Weld in cat

Has anyone ever used one of these on a 1*2? Due to the scarcity of 172 sports cats I was thinking of getting one off Ebay to weld in to a decat.

Not being impatient...ok I am! Has any one any experience of these and whether they will get through more than just the first MOT?

That is exactly the one I have welded in to my clio, not had an mot yet sorry but otherwise running okay and EML off from lambda sensors. Would be interested to know if anyone had passed MOT with this too

I’ve got a decat and asked a local exhaust fabricator if they could cut my decat and weld in some V band flanges on the section cut out and onto the new cat so that I can simply swap them in and out come MOT time. My local tester is very good and haven’t had issues yet but only a matter of time

Yeah I just thought a 200 cell would be the way to go for less restriction

Well, I’ll let you know today (as I’m going to fit one to mine) and I’ll MOT it tomorrow too.

My car is the perfect test for this conundrum. It makes 185 (dyno) on various mods and has a straight through exhaust currently. I’ve never known the car any other way.

Everyone says a cat makes no performance restriction on these cars from what I’ve read. I’m very sensitive to power/feel changes & will report back.

I’ll be annoyed if it loses the low down grunt the car has that’s for sure.

The verdict is?

I got a magnaflow cat, breezed through first MOT, scraped through second time.

If you're keeping one of these cars long term, you'd be bonkers to replace the efficiency of the OEM cat.

Sorry, only drove about a mile or so back home as my head’s been pounding. Almost abandoned fitting but.. MOT tomorrow.

Honestly though (from the brief drive) I’d say below 2krpm it feels a bit more Wooly, not as crisp & snappy.

Best bit about this car is how different it is to my stock car, even from 1500rpm you can snap the throttle and it reacts & at 1800rpm it felt good but now it’s ever so slightly blunted it to the point you don’t want to let it drop that low in the revs (I never would in my stock car). That might sound an odd way to drive it but this car seems really torquey at low revs and I find myself always poking the throttle at 1800rpm as it reminds me of my old 205, it’s nothing like my stock car.

Once it’s got past that initial response part I didn’t really notice any difference in the mid range and as yet I haven’t revved it.

I’ll report back when I’ve had a proper drive.

It’s not much quieter though (sadly)

I cant wait to get my resonated centre section on to (hopefully) lower the low revs drone. I'm half thinking of keeping my original can on for now, I cant see anyone theiving it around here😬

For what it's worth the cheap sports cat quieted down my unresonated ktec a lot, nice tone now compared to before so not bothered with adding silencer back in.

Good luck with the MOT tomorrow @jameswrx , if yours passes emissions with that cat that's good as mines due this month too, one less thing to worry about

I've had a magnaflow fitted to my 182 decat pipe earlier this year. Passed the not fine in September. The year before the same tester said it only scrapped a pass with the original cat in place.

It may well be better for noise on the motorway etc, need to get some more seat time as felt like crap today so couldn’t do it.

Did manage to also bin the LED fog lights for OE and bin the black painted grill for OE. Was quite satisfying snapping that up and stuffing it in the bin.

I suppose the question is, for how many years will they get through an MOT

Here are some actual numbers for comparison.

OEM 182 Cat:

Brand new magnaflow cat -

Fast idle CO Level: 191% increase.

Fast idle HC Level: 98% increase.

I see what your saying but I was assuming that at 20 years old my original cat is probably not long for this world...that and the £500 that's being dangled in front of me to sell it for scrap😆
