This is the BOFI Racing T2 Low Mount Turbo Manifold for Mazda MX-5 NA and NB- It’s a mouthful to say but boy oh boy is there a lot to say about it.

Designed between BOFI Racing and DaveFab with Quality, Reliability and Cost at its core. We want a product that can put up with the abuse we want to put it through on track and we want to have creature comforts too.

We want to be able to manage the heat in the engine bay as efficiently as possible so we can keep on the track for lap after lap. Because Seat Time is always better than Wrenching Time. 

Seat Time > Wrenching Time. Every time.

What’s in the BOX?

You’ll receive a BOFI Racing, Manufactured by DaveFab, Low Mount T2 Manifold with 3″ downpipe.

  • 3″ Downpipe to 3″ Vband – Note, this is to a point in space, roughly where the cat begins – it is in line with the rest of the exhaust system and your existing exhaust will need to be modified to fit or a custom 3″ system installed back.
  • A 1.6 kit will only work with a 1.6 engine, a 1.8 kit will only work with a 1.8 engine – downpipes are agnostic and will work on all NA or NB cars. They finish at the same position for both engine sizes.

A Quality Oil/Water Kit will also be available for purchase, this will include Oil Feed, Drain and Water Lines.

Manifold Studs are available separately.

We Can Install This For You

We've designed our workshop services to be easy to book and pay for online. To book, you'll need to pick a date and time that suits you and then add the products you want to be installed.

Each workshop product is a labour price only. We've recommended some products on each page, but you can also find other compatible products at the bottom of the page. This way, you know exactly what product you're getting and how much its costing to fit.

Add both the workshop service as well as the product to be installed to your basket and proceed to the checkout. Once there, you can confirm your dates and process the order. Occasionally, some products may require confirmation, when this happens we will make sure we have the stock to fulfil the install and get back to you within 1 working day.

If you have any questions, want a bespoke installation or would prefer to book over the phone, give us a call on +44 (0) 203 795 0515 or send us an email at [email protected]
