Catalytic Convertor, Aftermarket, MX5 Mk2

SKU: SI4681

Quality aftermarket replacement catalytic convertor.

This is a quality aftermarket replacement unit for the Mk2 with the one piece cat convertor and centre pipe. The existing pipe will need cutting just after the cat section and this new cat section fitting in its place whilst reusing the old centre pipe. Supplied with all the required fittings and gaskets.

Fits all Mazda MX5 Mk2 models, 1998>2000 5 speed manual transmission only, with a one piece cat and centre pipe.

Please Note: This cat is only suitable for vehicles that were registered BEFORE March 2001. After this they need to be type approved. If you have a vehicle registered after this date, please contact us as we can source them for you.

Fitting tip: Remove the complete centre section fron the car. Offer the new cat up to the old pipe ensuring that the bolted flange ends are level. Mark and cut the old pipe about half way down the straight part of the pipe. Refit using the joining sleeve and clamps provided. Please see the extra photo for a diagram of how it should fit together.

We had the catalytic converter removed from our MX by persons unknown. Bought this as a replacement and fitted straight on. Fortunately they didnÆt cut on the manifold side of the flange and they left enough of the rear of the exhaust to fix onto. Not had the CO levels checked but the fitting was spot on

Works brilliantly, highly recommended! My Mk2 NB 1.8S MX5, 64,000 miles from new and in immaculate condition struggled to pass its MoT for the past 7 years, finally my MoT tester said the high CO2 must be the Catalytic Converter because everything else has been changed over the years and it only failed on CO2. Fitting this replacement cat, that cost ú100 delivered, and immediately the carÆs CO2 emissions readout went from red to green! Perfect, thank you MX5 Parts. Note that I had previously changed the Lamba Sensor because the car was running a little rich which probably helped to kill the old cat over the past few years.

I was skeptical given earlier reviews, but none were recent. My cat died, so replaced with this one a few weeks back.Went through its MOT today:fast idle CO 0.19% HC 93natural idle CO 0.22%So far so good. Assume it will be same story next year.Fit and kit is good.

It does the job. No doubt on it.1°) It fits perfectly with the Centre Pipe, Aftermarket, MX5 Mk2[SI6469]. Combination of both gives you the same length than the Mazda OEM one. Easy to install, you just need joint sealer.2°) Concerning MOT (or Contrôle Technique in French language), at the beginning of the check it does not pass cause cat convertor did not reach high temperature enough to ensure a good burn process. Finally after the inspector accelerated the engine at 5000 rpm during 5 min., second check was OK (Both CO=0% / Lambda=1.030).It did the job :-)

Likewise mine had done less than 1K miles on the car, failed it's MOT on emmisions, changed the cat, instant pass, I also wouldn't recommend this item as a replacement, spend a bit more & get a decent cat as this item just isn't up to the job, PH.

This catalytic convertor had little or no effect on my MX-5 at all.It fitted with no problems, and the exhaust-system was completely airtight, but the CO levels was way too high to get through the MOT test (0,7%).After mounting an original Mazda convertor the CO-levels dropped to 0,002% !I also noted that the original Mazda convertor is almost twice the size of this product...?Thankfully, MX5 Parts made me a full money refund - but even though I like MX-5 Parts and use them a lot, I cannot recommend this catalytic convertor.

Delivery Information - MX5 Parts

We understand that its really important for you to receive your goods in a timely fashion and for a competitive price. To ensure that we can deliver this we have developed a strategic partnership with both the Royal Mail and our courier partner, Think Worldwide.

At the present time, we only offer one delivery option ‘our carrier’. We will dispatch your goods with the most suitable carrier, for main land UK deliveries this is normally Royal Mail 1st class for packages weighing under 1.5kg and Think Worldwide for those that are over.

Our delivery charges are based on the weight of the consignment and the destination address. For UK mainland deliveries they start at £1.97 for a package weighing under 300g and rise to a MAXIMUM of £9.95 for a package weighing 1.5kg or over (EXCEPT very large bulky items that have an additional shipping surcharge added). The exact delivery cost will be clearly displayed at checkout.

Delivery times are estimated at 1-3 working days by Royal Mail, and 1-2 working days by Think Worldwide for mainland UK addresses. If you order before 3pm, Monday to Friday, we will dispatch the same day. If you order after 3pm, we will try to dispatch the same day, but if we cant it will be the next working day. Items ordered after 3pm Friday or over a weekend will be dispatched Monday. Items dispatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be dispatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items. If we have run out of stock and can’t dispatch your order the next working day, we’ll email or phone you with a revised dispatch date. You can then either accept the revised dispatch date or cancel the order, as you wish. Please note, shipping times are an estimate, and can not be guaranteed. Please note that during special offer periods, dispatch of your order may be delayed slightly due to high a volume of orders.

A signature is required for ALL orders delivered by Think Worldwide. Someone must be at your delivery address to sign for your parcel between 8am and 6pm on a working day. Please send it somewhere it can be reliably signed for, like your place of work, a neighbour, or perhaps your grans. We can (but we don’t like to) ask the courier to leave your parcel without a signature. If we do this, it will be YOUR responsibility if the parcel is lost or damaged. If you want it left, you need to give us your express instructions in the ‘additional information’ box at the end of the checkout process. It would be helpful if you could also indicate exactly where the package should be left.

If you need to change your delivery address, for any packages that have been dispatched with Think Worldwide, there will be an additional charge of £9.95 if the package has already been dispatched.

Please remember, even with Royal Mail deliveries, that any items which are too large to fit through your letter box will need someone to be available to receive the delivery. If the item cannot be delivered, you will be carded and given the option of either a re-delivery or you can collect your parcel from your local post office depot.

Orders sent to countries outside the UK will be sent VAT free, however please note that on all international shipments, the recipient is responsible for any local VAT, import duty and other clearance fees that may be charged.

Our Guarantee - MX5 Parts

We guarantee that you’ll be satisfied with mx5parts!

We are an independant, family company, run by a dedicated team. We aim to be the kind of company that we’d like to deal with if we were you. You have our absolute commitment as fellow MX-5 owners, car nuts, internet users and hard-working people that you’ll be satisfied with mx5parts. If you’re not, let us know and we’ll sort it out!

We guarantee “always fair prices”

MX5parts maintains an everyday savings pricing policy. We watch other retailers closely and maintain competitive pricing. The internet being the beast it is means that any Tom, Dick or Henrietta can set up a website in their back room and charge bargain basement/off the back of a lorry (guv) prices. Often they will have no stock, no returns policy, questionable security, no guarantees and of course poor customer service. MX5parts strives to be open and honest, so we will never inflate our prices to set up an artificial ‘sale’ (a common – and illegal – retail practice).

It is inevitable in an open market like the internet that there will be some individuals selling some items cheaper than we do, and some selling them for more than we do, just as in the high street. We take great pride in offering a fast, efficient, friendly and secure shopping experience, with great products at fair prices. We encourage our customers to shop around, but are very pleased to welcome them back again and again.

We guarantee to despatch your order when we say we will

If you order before 3pm, Monday to Friday and we have your items in stock , we’ll despatch the same day . If you order after 3pm, we’ll still try to despatch that day but, if we can’t, we’ll despatch the following day. Items ordered after 3pm Friday or over a weekend will be despatched Monday. Items despatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be despatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items. If we have run out of stock and can’t despatch your order the next working day, we’ll email or phone you with a revised despatch date. You can then either accept the revised dispatch date or cancel the order, as you wish. Please note that during special offer periods, dispatch of your order may be delayed slightly due to high a volume of orders.

We guarantee to replace any goods which aren’t suitable

We guarantee to accept back any goods that you do not want, are not suitable, have changed your mind about, infact, for ANY reason, provided the goods reach us within 30 days of dispatch from us, in their original condition and packaging. Please tell us why you are returning the items, just for our records. The original purchase price of the goods will be refunded on to the card that was used for their purchase. Sorry, but we can not refund the carriage costs.

We guarantee to sort out any problem with your order

Just contact us if you have any problems with an order from mx5parts. We’ll tell you exactly what steps we’re going to take to rectify the problem.

We guarantee full warranty support on all items

Just contact us if you have a warranty problem. All goods supplied by mx5parts are from official sources and are covered by the normal manufacturers warranty.

We guarantee that we will only charge your credit/switch card when your goods are dispatched

This is your right under UK law and, if we do anything else, it’s illegal!

(Please note: This doesn’t apply however if you have chosen to pay via PayPal. Due to the way PayPal works, you are effectively sending the money to us rather than us asking for it so in this instance we will have received payment at the time the order was placed and not when it is ready for dispatch).

We guarantee that we won’t pass your email details on to anyone else

Absolutely not. All your details are treated as strictly confidential. We’re internet users, too, and we know how annoying unsolicited email can be. We wouldn’t risk annoying you by being the cause of it.

We guarantee that shopping with us is safe

Our website uses the very latest secure server hardware and software, and is certified secure by COMODOs hackerguardian facility ensuring we are continuously PCI DSS Compliant.
