Hi all, I have decided to make this post as I'm not aware of many people who have gone down this route - hopefully will provide some help/feedback to anyone who has been considering this. I must stress that this is not a guide on how to install the manifold (how to do that is readily available online), I am just sharing my own experience. I reached out to Mike from TD and ordered the Unequal Length manifold they offer to be shipped to me - it is well known that this manifold produces good results and is highly recommended by others online, but due to work commitments and location, it was not easy for me to commit to a journey to TD in Warrington. My first job was to get an additional gasket and a set of bolts as I did not choose to get an aftermarket overpipe, then I purchased some DEI titanium exhaust wrap and wrapped the "downpipe" section between the manifold and overpipe pieces. With the exhaust wrap applied, removing the OEM manifold was the next job. This was not as hard as anticipated - I bought this 3-IN-ONE Professional High Performance Penetrant Spray from Halfords and sprayed some on all the bolts. I left this to soak in a bit and unplugged the o2 sensors and the bolts came off without much struggle. All in all, the whole DIY removal and installation took about 2 hours. Thoughts so far? Even without a remap (I am booked in to get this done at Abbey soon), the car feels noticeably more responsive. I feel a big improvement in torque around 3-4k RPM. I also love the exhaust note it makes (I am running this manifold with a HKS drop in air filter, Cobra resonated catback exhaust and stock overpipe/frontpipe). I am yet to get the CEL but it has only been a day and I'm sure this will come until I get the remap. All in all I am very very pleased with the outcome and am looking forward to getting the remap. Will post some results as soon as I have them.
