I got mine off EBay from MTC Motorsport - about £240 good quality and they look fab!

Excellent result Steve. Thanks for posting. I had always been assured the secondary cats would do the job on their own, but it's good to actually have it confirmed

No excuses now for people not to buy and stage 2 map

How much louder is the exhaust when the flaps are open in sport mode?

20% or 30% more louder for example?

Not sure about a percentage but it's noticeable and sounds good!

Took it down to EFI parts dyno this evening (Runcorn).

Pushed out 534BHP and 590 pounds foot torque. Suffered a little bit with with tyre slip.

2014 M4 (not a comp one) MTC catless downpipes and Bootmod3 Stage 2 map. Running on a mix of VPower and Sainsbury's super unleaded fuel.

Defo needs a better intercooler as well.

hmmm thats o n the little low side is it no.. stage 2 is meant to be 500whp which is about 550 ish?

SteveChester · 03-19-2019, 02:48 PM

I was thinking 540ish so not that far off.

Smee · 03-19-2019, 03:07 PM

Post your graph up still. I want to compare mid range

I think there is a dyno mode the M4 needs to be in to prevent wheel slip which I can see if the 2 bumps in the chart???

Yep, you're right, there is a dyno mode for the car. There's a video of how to set it on ProTuningFreaks website.
