The XForce cat-back exhaust system for the Nissan 350Z, built for the VQ35DE from 2003 to 2006. It replaces the factory exhaust from the catalytic converters rearward with twin 2.5" mandrel bent premium stainless pipework, an x-pipe, twin hotdog resonators in the centre, a crossover dual muffler rear design and 4" polished stainless angle cut tips. It is designed to bolt directly to the factory exhaust system.
The twin 2.5" sizing is the defining choice here: each pipe is narrow enough to keep gas velocity up through the low and mid range, while the two paths together supply the flow area the engine wants high in the rev range, which is why the gains sit across the range rather than only at the top. Mandrel bending and smooth transitions serve the same end, holding a constant bore through every bend so there is no step or crush to slow the gas. Sound is managed in two stages: the x-pipe ties the two paths together so pressure pulses equalise across them, and the twin hotdog resonators in the centre take frequencies out early, which is what lets the crossover dual muffler at the rear stay high-flow and still deliver a tuned note rather than a coarse one.

- Twin hotdog resonators in the centre
- Unique crossover dual muffler rear design

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!
