Stainless Steel Exhaust Manifold 4-2-1 MX5 Mk3/3.5/3.75 Reviews

Read MX5parts Reviews

I.L.Motorsport has launched a brand new line of Stainless steel headers. This is a fully stainless header with 4 into 2 into 1 pipes is designed so that it delivers maximum HP and a maximum high flow. They have tested numerous designs to get to this special looking finished header. This price for this header is only available as long we have this current stock. These are now supplied with an oxygen sensor relocation kit which is required to fool the ECU into thinking the first cat is still there and stopping the MIL light coming on. You will need to install a bung behind the second cat and using the supplied wiring harness, move the second O2 sensor down, after the secondary cat. Click here for fitting instructions.Fits all Mk3, Mk3.5 & 3.75 models, 2005>2015Please Note: As from January 1st 2012, the UK MOT laws changed regarding catalytic convertors. Any vehicle built after 1992, MUST have a catalytic convertor fitted regardless of whether or not it passes an emissions test. Any car presented without a cat fitted will fail. Effectively, these stainless manifolds remove one of the two convertors fitted to the Mk3, so we have no choice other than to recommend that they are for off road use only. As your car would still pass an emissions test wth one of these manifolds fitted, it is unclear as to whether or not the one remaining cat is sufficient, so we would advise checking with your MOT tester before fitting this manifold if the car is being used on the road.

I have just fitted (by a garage) 'Stainless Steel Exhaust Manifold, 4-2-1, MX5 Mk3' along with the 'Stainless Steel Race Exhaust Rear Silencer, MX5 Mk3' to my 2.0 Convertible...When I went to pick the car up when it was finished, just had to go for a spin... Went over the 'Auckland Harbour Bridge' (via Albany) then to Puhoi, stopping of at Orewa for a pint then returning home to Unsworth Height, North Shore, Auckland, New Zealand...We were really pleased with the results, as this was done to my fiancée Nikita’s MX5 as gift... now all I have to do now is save up some extra cash and repeat the whole process again to my MX5...What an incredible piece of engineering!! Thanks for your help, this MX5 sounds like a true sports car indeed!

I have now run my 2.0 coupe for a week after having been fitted with this manifold ( by a garage) in conjunction with an IL motorsport back box from Mx5 parts and a custom de-cat mid pipe. The result is superb with a perfect deep note, no rasping and no poping. I am very pleased with the result. The garage fitted the supplied o2 tricking sensor without any problems The car ticks over at 900 rpm without hunting using 97 ron fuelThe quality of the manifold and back box is superb. There are loads of threads on forums regarding mk3 exhausts, I did my own thing and thank goodness it paid off.Do not hesitate to buy this product if you want high quality kit without the boy racer "noise"I am happy to talk to any enthusiasts on this subject. contact me at randmpilk@yahoo.co.uk

I think it's a quite good product, but it's not well made as the 4-1.The car is better with it, but it's easy to have a good gain response without the original headers.
