Hey All!
Finally the long awaited video is now live! We put our gutted cats back to back on the dyno against our new test pipes to see which one sounds the best and gives the biggest increase in torque and power!
All parts are available to purchase at mod-stock.co.uk !
Thanks for Velocity Tuning for hosting us on the day! (@Velocitytuning) velocitytuning.uk
This video was filmed and edited by George from the FLOORit youtube channel! check his channel out here / flooritofficial and on instagram @M3_Floor

This is one of the smoother dyno charts I ever saw. Proof that if you know what you are doing you can actually improve efficiency and make car sound better too. Well done Modstock and Tommy

Very good vid. Pretty nice and easy way to understand the upgrades .

@chrisdm23 3 года назад

Perfectly done video . Used the info to determine the direction I wanted to take and I must say knowing the outcome in advance is really helpful . I went with test pipes and tune and boy does it sound amazing . I can feel the difference in when the power comes in for certain . If it’s sound your after then this is the combination . Thanks for taking the time to explain everything in such great detail . Very very well done !

This video answers a lot of questions that e9X M3 owners usually ask (Gutted vs. Test Pipes vs. Stock). Thanks a lot :-)

1.31 multiplier to get to bmws stock hp figures on stock car haha

@gw7514 2 года назад

Power and torque seems low for wheel horse power the it looks like stock wheel horse power was 320hp peak, is that right? Have you changed the spark plugs to see if that makes a difference?

@Stanley_Baby Год назад

Was the muffler and resonator still in the mix with the test pipe or was it lit straight through exhaust?

@mod-stock 7 месяцев назад

Secondary cats and factory resonators still insitu

@MasterSteve_117 27 дней назад

I am confused as a non native speaker. What do you mean by stock exhaust (1.5 mod)? What is a Backbox?On the one hand you say it’s stock and then you say mod? Please elaborate.

@FlagnarBoobz 3 года назад

What was the backbox mod of the car? 1.75?

@mod-stock 3 года назад

Yeah 1.75 👍

@carlmaynewheeler 2 года назад

Chrs is GOD. My M3 is so much better after his mod.

@Mattathias-e9b Год назад

I've actually lost power significantly after gutting my cats, apparently its the empty chamber, no velocity of the gas. its so bad I'm taking the car back tomorrow. Anything that could be done to get my power back without changing to straight pipe?
