Was bought this as a gift. Easy install even came with the EGR cap! Sounds amazing gave the exhaust that added rasp I was after. Like others have mentioned if you want to keep the EGR pipe then you'll have to get creative. But for me deleting the EGR was no problem.

It sounds tinny and it rattles against the tunnel beside the gearbox! :(

Doesn't fit my LHD 1.8l mk1 NA miata.1st : had to take off the steering piece between steering rack and steering wheel.2nd : it hits the chassis under driver's side (LHD car) so it can't be mounted correctly on the engine.3rd : EGR solenoid pipe isn't at the good place so I can't plug them together (wrong position and angle). Yeah a big waste lf money for me.

Looks nice but not all that great of a product.Simply does not fit. The E.G.R pick up on this manifold is miles away from where it should be. Only possible to fit if you don't mind removing your E.G.R.Annoying that it doesn't say anything about it coming with a gasket because I went and bought one and now I have 2 sitting around, Although the complimentary gasket is nice Id like to know I can save money by buying here.

I've had mine for over 6 months after finding out about the 97 UK spec cars being 475mm not the normal 440mm so I got this and a cat to help with a full install and its been problem free. downside was that the finish started to fade quite fast but then my car was a daily driver and I clocked over 200 miles a week easy.Installing it was easy but as others have posted the EGR pipe did need a little convincing but nothing major.sadly my MX5 was stolen and torched and while this did make it out of the fire in one peace the hood had melted all over it so when I get my 2nd MX5 I'm going to throw one of these on their asap.

As per usual this arrived very quickly and does look fantastic. It gives a lovely noise and possibly a small increase in power, though I cannot verify this.The only reason this is given a lower score is because the exhaust gas return does not fit with this. From cylinder three the EGR pipe is angled down 15-20 degrees whereas it is level on the stock manifold. As a result the only way I have managed to keep the EGR is to disconnect it from the inlet manifold and use some washer hosing and cable ties to make a \'secure\' fit. Aside from this the only thing I could think of would be reforming the pipe with heat but I really shouldnt have to do that.If it wasn\'t for this it is a top quality product that would\'ve taken five minutes to fit, rather than several hours messing about with one pipe.Editors Note: Sorry to hear you had trouble fitting this item. As we take any issues with our products very seriously, we will certainly be forwarding your comments to the manufacturer for their view on the matter.

well as always the item was with me before i could blink, cant fault the quality and price of the manifold and has made a real difference to the performance along with the stainless exhaust for £183. If your thinking of fitting a performance exhaust you need to fit it along with this manifold,the only advice i would give is to heat wrap all the pipes and air box etc as it does get very warm with no heatshield.

Ok. After 3 years on the car, the stainless steel is still holding up well, but the welds are beginning to crack. I had one of the first adapters made for the Roadster, which succeeded in misaligning the rest of the exhaust, causing bad wear to the PPF. Since then, I have dumped this part, and fitted a 440mm cat. The manifold also causes the exhaust to hang very low, so watch out on lowered cars. Whereas previously, the leading edges of the chassis rails might have caught speedbumps, with this manifold fitted, the exhaust might clip things as well.

I recently purchased and installed the ss manifold. Delivery fantastic. Easy to install. I had to leave off the stabilising bracket to the gearbox as it got in the way of the oxygen sensor. The product is is very well made from heavy duty stainless steel and professionally welded, it looks very nice.You have to address the heat problem as there is no heat shield and it is very close to the air filter. I have a KNN conversion and always wondered what to do with the cold air pipe. I have fitted the air pipe to the underside of the bonnet directly behind the passenger side headlamp. I have modified the trim behind the lamp with a small cutout. The gap behind the lamp is sufficient to allow enough air to flow through the pipe.Fix the pipe to the underside of the bonnet with cable ties. It's easy and only takes a few minutes. Another way is to fix a heat shield around the filter. A little more complex.Overall a nice piece of kit. I notice some improvement in performance...birdseye.

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.

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.

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.
