Video: BMW M340i with the M Performance Exhaust sounds terrific!

View Forum Discussion

To be honest, the M340i with the M Performance exhaust now burbles in all modes, especially in the lower rev range.

BHPian karan561 recently shared this with other enthusiasts.

Had ordered the ///M Performance Exhaust (Part No: 18302464492) for my BMW M340i & recently got it fitted at Navnit Motors Andheri workshop. Check the above video for the installation & the exhaust sound.

Some pictures.

The quality was good, but nothing space age.

 ///M Plaque on the side.

The OE exhaust needs to be cut.

So the M Performance can slide over its piping and then clamped.

The End Can has the ///M Performance Logo embossed.

Here's how the underbody looks after the installation.

Ready within 90 minutes.

There's an immediate increase in the Pops/Bangs & Burbles which is good as it sounds all-natural & powerful and not fake stuff which is coded in or achieved via software trickery. This is why I really liked this upgrade as it was a BOLT-ON fitment without any engine/check lights to remove and required no Software/OBD connection & No Coding.

It's a known fact in the M340i Owners Group India that the 1st lot of the M340is was the loudest hence after this MPE upgrade the car is only about 20-25% louder than stock in Sport Plus Mode. Eco Pro Mode was still the quietest however this mode is now marginally louder and burbly than stock.

To be honest the M340i with the M Performance Exhaust now burbles in all modes, especially in the lower rev range. Upshifts Farts have gotten louder where as During downshifts even in comfort mode you get some drama which gets amplified further in sport/+ mode.

Another point to report is that the cold start is significantly louder now. Overall the perfect upgrade which keeps my warranty intact.

Here's what GTO had to say about the matter:

Man, that sounds insane! A wicked car became even more evil and the on-your-face says it all. One of the best parts about driving a fast petrol (vs diesel or EV) is the exhaust note. After my City & Civic free-flow exhausts, I'd told myself that I would never drive a petrol car without an after-market exhaust. But you've taken it to the next level. What a car and what an exhaust note!

This is the best. On long road trips with family, you can tone it down.

How much was the total? And what are you doing with the old exhaust? Am guessing absolutely no effect on warranty since everything is official?
