All NewNow supplied as a silenced bypass pipe, in 100% polished 304 Stainless Steel, complete with all fixing bolts and gaskets.100% Stainless steel catalytic convertor by-pass pipe (cat replacement pipe). For the removal of the catalytic convertor from the exhaust system.All Mk1 1989>1998There are three different cats fitted to the Mk1, 1.6 or 1.8 upto 1994. This cat is 370mm in length.1.6 or 1.8 from 1994 to 1996. This cat is 440mm in length.1.6 or 1.8 1996/8. This cat is 475mm in length. A cat replacement pipe is NOT available for this model.The safest way to ensure you order the correct pipe is to measure the distance between the two mounting flanges of your existing cat.Supplied complete with gaskets and bolts.Please 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. We would advise checking with your MOT tester before fitting this pipe if the car is being used on the road.
Even though this is a 'silenced' bypass pipe, the removal of the catalytic convertor WILL result in an increase in exhaust noise! Some like it, others do not. Beware!

Did increase power of car slightly but I can't say the noise was any louder which I was a bit disappointed with.

This is an excellent Mod to free up a few bhp and improve the sound of the MX5 exhaust for a relatively small amount of cash. Mine came the day after I ordered it and I wasted no time in getting it fitted. I was really impressed at the quality of the stainless steel, it looks great!For the first week or so, the car did not sound any different, however, no that the carbon has had a chance to build up inside the decat it sounds quite throaty when you accelerate. I was a bit worried that it would make my exhaust sound loud before I bought it, but it's only marginally louder than the standard Cat. Mid range acceleration is also better.A worthwhile mod, and it would sound even better with a full stainless system!

easy to fit,combined with my mx5 parts stainless system it sounds nice..not too loud and reminds me of a janspeed on an old escort rs 2000.was worried it might be too loud as the stainless sytem is fruity..but its fine. maybe a slight loss of bottom end power (back pressure loss?) but goes better up the rev range. worth getting.

Well worth fitting if the back half of your system needs replacing anyway (as mine did); you may as well free up all those strangled ponies while it's all up in the air. Actually a very straightforward swop, as the part is a perfect fit and superbly well made ... access is the big issue, of course, so if you have a four-poster ramp knocking about at home, then have at it, but otherwise I'd recommend bunging your local independent tyre & exhaust place £20 to do the job for you. They'll have all the kit, and be used to doing exhausts in their sleep ... plus you get to have a good nosy round at the 'hidden' bits of your car.A great addition to my Eunos; fitted at the same time as the single exit SS exhaust (also from MX5Parts), so the car sounded far healthier and pulled noticeably better on the journey home. Only very slightly boomy at motorway speeds, but a world away from the Saxo-with-a-drainpipe image you're probably fearing. Highly recommended, as long as your car's early enough not to need a cat.

I order this part along with the Parts Exhaust for my 1.6 the day before new years eve. Both parts were delivered to the garage i use on monday 4th (the day i arranged for the car to go in). My mechanic said they were absolutely no problem to fit and teamed up with the K+N filter charger i fitted produce a delightful sporty engine note and the car is free revving through 1st to 3rd gear like a dream.Great service and parts.
