The XForce 2.5" performance centre section for the Mazda MX-5 / Miata NC. It is a direct replacement for the restrictive factory centre section between the header and the rear muffler, built from 2.5" mandrel-bent 304 grade stainless steel pipework in a brushed finish, with two 304 stainless hotdog-style resonators integrated into it. It retains the original bowl flange connection to the header and the original ring flange connection to the rear muffler, keeps the factory exhaust hanger locations, and carries factory-style O2 sensor ports for cars fitted with post-catalytic oxygen sensors. It is supplied in two pieces joined by a slip-joint connection.
The mandrel bending matters as much as the 2.5" figure itself, because a mandrel bend holds the bore at full diameter through each curve instead of pinching it where the pipe turns, so the flow path stays the same size at the bends as on the straights. Using 304 stainless for the resonator bodies as well as the pipework means the whole section shares the same corrosion resistance, not just the parts on show. The slip joint between the two halves is the practical detail: the pieces can be slid and rotated against each other on the car, so the bowl flange at the header, the ring flange at the muffler and the factory hanger points can all be brought into line before the joints are secured. That suits an owner after better flow and a deeper tone with the factory rear muffler still in place, or with an upgraded axle-back fitted behind it.
Features
- 2.5" mandrel-bent pipework for smooth, unrestricted exhaust flow
- 304 grade stainless steel construction with a brushed finish
- Dual 304 stainless steel hotdog-style resonators to refine the exhaust note
- Retains the factory bowl flange to the header and ring flange to the rear muffler
- Factory-style O2 sensor ports for vehicles with post-catalytic sensors
- Two-piece slip-joint design, factory exhaust hanger locations retained
Fitment
Mazda MX-5 / Miata NC. Replaces the factory centre section and runs with either the factory rear muffler or an upgraded axle-back system. Cars fitted with post-catalytic oxygen sensors are covered by the factory-style O2 sensor ports. If you are not sure whether your car is covered, message us with your year, trim and engine and we will confirm the fit before you order.
Let customers speak for us
Solid shipping ,good communication ,great product 5stars all the way
First let's preface I have tried three other tuners. Not bad mounting or name dropping as they all were solid tunes. But Daniel just has that magic touch when tuning the 1.6 platform.
The car has a buttery smooth power band making the car feel like a larger displacement six cylinder over a turbo charged car. Plenty of fun to be had at any speed or RPM range.
He will take the time to get you dialed in perfectly for your car. No canned tunes here folks. And if you are a EK1 user three tunes for the price of one simply can't be neat.
I received the Stage 2 tune. Here are my thoughts:
- The shifts are buttery smooth
- I love the auto shift @2000rpm when cruising around town; saves me an extra 2-3mpg overall
- Driving in traffic is a dream now, much better than stock. I don't even hear that annoying shifting fork anymore, lol
- Any and all DCT slips are gone
- The increase in torque limit! This opened up my N75 Stage 3 ECU tune; I can feel the difference. The last time I dynoed, I got 289 lb-ft of torque. But it feels much more substantial than that!
- The clamping force is unreal. I did a run from a dig, and it hooked and slammed through the gears all the way to 7k rpm in each gear. Amazing.
Conclusion: This TCU tune is a must-have. If you have an N75 ECU tune, it is an absolute game-changer! Especially with the Redline MT-LV fluid that I'm running. I can't wait to get my retune with water meth injection. Daniel and the rest of the N75 team are the best!
Works like suppose to be fast delivery after installation 5 minutes drive TPMS sensors lights off everything is normal like from factory 👍👍👍

Product was very easy to install and what a difference in shifting also n75 was super awesome to deal with will shop here again
After using the N75 tune for a couple of months, I can confidently say that it offers the best value for your money on the market. I've tried SXTH and LAP3 tunes before, but since switching to N75, I won't look back. With top-notch customer support, it ensures your car performs better, turning heads at every car meet.
Been running stage 2 off that bat and had some problems here and their regarding fueling. Daniel has been with me the whole way, answering questions and adjusting tunes while adding revisions whenever asked. He answers every question I ask even when they don’t relate to tuning.
Highly highly recommend N75!
Daniel's tuning and customer service makes this product a 10 out of 10. I'm new to tuning and he made the process a breeze. I literally laughed out loud when I first drove the car after installing the stage 2 tune. I still can't believe the difference.
Love the intake, fitment is superb, instal was easy and best of all n75’s customer support is stellar and way above average!
