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!

As ever, perfect service. Looked lovely - fitted no bother.Sounds lovely, a light "chuffing" at low revs, growing to a rasp in the midrange, topped off by nastiness at full chat. Marry this to a 4:2:1 stainless manifold and a twin-exit silencer...pure filth really :).

There's a lot of speculation whether or not the decat makes a difference. Firstly I had the mx5 parts exhaust already fitted and after fitting the decat I noticed that the sound was slightly deeper but not any louder or raspy. I have a 1.6 Eunos auto and as every one knows they're a bit slow off the mark, well I can happily say fitting the decat has made it a lot more lively and responsive. After I've done the 14 degree timing mod I'll report back for all of you with autos to let you know if it's made more difference. All in all great product, fast delivery, great service as always and would recommend this art as well as the mx5parts exhaust.

A pleasure to recieve shuch a nice and well made part, had to take it next door to show a neighbour it looked so nice.Easy to fit but I needed a grinder as others have mentioned. I cut the two front easily then dropped the rear off the rubber mounts for easy access. You cant even fit it the wrong way round as the hole spacing is different.Exhasut note excellent, I dont find it noiser, power band between 5k and 7 k smoother.Many thanks.

Received this item the next day from ordering within the allocated hour slot from the courier !! - what can i say? well, the finish and fit are both superb (fitting took about 20 mins) after a squirt of oil on the existing bolts.i put a blob of gungum on the gasket, while the car was up in the air and bolted it all home.sound-wise it has a nice throaty roar on half/full chat, while idling and cruising isn't compromised. (great for roof down high street blats, echoing off all the buildings !)power-wise, - a bit more response and deffo another notch up on the grin factor.value-wise - worth twice its money, for sure.A highly recommended product and supplier in summary.

Easy to fit once the old cat was removed ( having soaked the rusty nuts and bolts in Plusgas for a couple of hours)I'm using it with the standard backbox so no real increase in noise levels. Bit smelly on cold startup, subjective seat of the pants driving feels like more top end and less torque between 2500 and 4000rpm.

Looks great. Feels solid and well made on the outside.However...Lasted about 6 months before the perforated internal sleeve started sounding like a doorbell.Now intolerable.This makes me sad.Editors Note: Sorry to hear you have experienced problems with this item. As with any issues you may get, please contact our customer services team in the first instance as this part is well within its warranty period so we would be more than happy to replace it for you.
