5 reviews for Performance exhaust manifold for TD5 Defender and Discovery

  1. Rob Huntley

    The Discovery TD5 exhaust manifold which I ordered on a Monday arrived in Adelaide, South Australia the following Tuesday,
    very efficient. I have now had the manifold fitted and turbo lag has reduced especially when motor is warm and motor appears smoother. I am assuming and hoping no more warping issues.
    Thank you for your efficient service.

  2. Phill Everall

    A Quality product essential for keeping egt’s low when increasing power output. A smoother free flowing tubular design giving better air flow and eliminating the warping and subsequent stud snapping problems caused by the standard webbed mainfolds. Very recommended.

    A little delay due to covid shutting down the factory but delivery was otherwise faultless.
    Did need to diegrind some relief into the flange for it to miss the cylinder head bung and also had to take material off the underside front stud to allow a socket to fit. Somewhat annoying after having spent £££ extra getting it ceramic coated All fitted fine after this, not warped yet.. but early days and not been at full chat for any length of time to tell for sure.

      Thank you for your feedback Andy.
      Some cylinder head bungs are more proud than others (thanks LR…!) we also find some studs are not entirely straight in the head which can reduce clearance.

    I could tell right away this was a quality product just comparing it to the original , I only really intended to avoid any future warping issues , however as far as a bolt on item this have made the most noticeable difference with power across the board and particularly down low – less turbo lag and smoother . Very impressed

  5. John Rigler (verified owner)

    This is a top quality product. Fitted perfectly and I used the uprated stud kit for fitting. The only problem I had was the bottom front stud is a little tight against the casting preventing the stud spacer being used, but no drama in that. Performs and look so much better than the standard LR product. No hesitation to recommend.
